Inferior person achieve can science and technology (Urumqi) limited company, inferior person lacquer (Shanghai) limited company invents patent “ at was being made public jointly on January 31, 2023 alkyd of ability in swimming of a kind of biology radical and its preparation method and applied ” . The summary shows, the design that adopts preparation raw material and technology reachs his mutual answer match, make what narrate alkyd of biology radical ability in swimming not only more green environmental protection, and promoted stability significantly, have be able to bear or endure exceedingly goodly ability in swimming, corrosion resistance, tenacity and intensity, integral performance is good. Coating has the currents and other characteristics of a river that includes place to narrate alkyd of biology radical ability in swimming to store exceedingly goodly stability and application property, paint film holds a superior adherent force concurrently, be able to bear or endure ability in swimming and corrosion resistance, suitable scope is wide.

Oil is belonged to blame but renewable resources, as oil natural resources in short supply those who reach its price is ceaseless rise, on the market to using but renewable resources replaces a tradition the voice of oil radical resource is louder and louder. In addition, the paint that is raw material with oil / coating and printing ink not only drain valuable oil resource, and the volatile organic matter that discharges enlarge amount to the middle of air (VOC) , bring the issue that the environment pollutes. Accordingly, development environment is friendly model coating becomes Chongzhongzhi to weigh, especially coating of ability in swimming, basically develop way with respect to what make coating.

Alkyd holds larger proportion in coating, have raw material cheap the glossiness of easy, paint film and plump degree of good, adherent force is good, right painty wetability can be good wait for an advantage, wide application receives in the domain such as carpentry lacquer, industry lacquer, building lacquer. As the rapid development of coating of ability in swimming, the ability in swimming of alkyd is changed imperative also.

One of methods that alkyd ability in swimming changes are to use exterior activator alkyd emulsification, get moisture comes loose model alkyd. The bead diameter of the latex of alcoholic acid of ability in swimming of existing patent preparation distributings even, sexual price is higher, have good application in varnish and paint respect. But, the adds initiate to affect coating performance becoming film of a large number of emulsifying agent in the latex, and of paint film be able to bear or endure ability in swimming and adornment sex not beautiful, lost alkyd originally performance dominant position.

Another kind of method that alkyd ability in swimming changes is to use contain hydrophily base round monomer preparation alkyd, form water below the action that helps solvent then but dilute alkyd. The water of the patent preparation that although have,does not pass but alkyd need not use attenuant sex many emulsifying agent, but latex viscosity is taller, influence application property, and of paint film be able to bear or endure ability in swimming is poorer.

The method that at present relatively commonly used alkyd ability in swimming changes is the law that become salt, in introducing the carboxyl of excessive alcoholic acid element, recycle counteracts agent and carboxyl to counteract salt, get water-solubility alkyd. The sex becoming film of the alkyd of ability in swimming that gets into saline law and coating is passable, but its store stability is poor, bring about coating to appear extremely easily sedimentation, the problem that agglomerate, bring very great construction difficulty, and the endurance of paint film also exists to be not worth apparently.

Will look at present, blemish is narrated before alkyd of ability in swimming exists besides function besides, still put in particular environmental protection problem. Alcoholic acid of ability in swimming and coating of ability in swimming still make monomer of oil of in order to is the synthetic latex of raw material, search it is more and more important to replace the raw material origin that other natural resources regards petrolic as material of synthetic high polymer to become, get traditional petroleum products has important sense to environmental protection and managing oil natural resources replacing. And, certain dissolvent still needs in coating of common ability in swimming, useless paint film cannot biology degradation, bring environmental pollution and the risk that damage human body health thereby. Accordingly, develop a kind of integral performance exceedingly good and the colophony that accords with environmental protection requirement and coating, it is the problem that competence region solves urgently.

Be aimed at the inadequacy of existing technology, the purpose of this invention depends on providing alkyd of ability in swimming of a kind of biology radical and its preparation method and application, the design that carries preparation raw material and answer match, make what narrate alkyd of biology radical ability in swimming not only green environmental protection, reduce environmental pollution, and have excellent stability and integral performance, its regard ability in swimming as the material becoming film of coating, make paint film holds a superior adherent force concurrently, be able to bear or endure ability in swimming and corrosion resistance.

Opposite at having a technology, this invention has the following and beneficial effect: 1) the live thing that this invention offers base in alkyd of ability in swimming, the design that carries preparation raw material reachs his mutual answer match, especially will specific live thing base oligomer and constituent of oily etc of certain herbaceous plants with big flowers undertake conpatibility of medicines, have not only but second birth sex, decrease to be depended on to oil natural resources, more green environmental protection, and the stability that promoted place to narrate alkyd of biology radical ability in swimming significantly, make its can satisfy the requirement that long-term stability stores, have be able to bear or endure exceedingly goodly ability in swimming, corrosion resistance, tenacity and intensity, integral performance is good.

2) the craft preparation that narrates alkyd of biology radical ability in swimming to use “ to divide footwork ” gets, the control difficulty of reaction craft is small, reduce pair of reaction happening, maneuverability is good, make the stability of the product and integral performance promote significantly.

3) coating has the currents and other characteristics of a river that includes place to narrate alkyd of biology radical ability in swimming to store exceedingly goodly stability, store for a long time won't happen statified, sedimentation, agglomerate or the phenomenon of knot skin, application property is admirable, it is good that paint film adds exert oneself, can reach 0 level, be able to bear or endure briny sex ≥96h, be able to bear or endure ≥120h of ability in swimming, hold concurrently be able to bear or endure exceedingly goodly ability in swimming, be able to bear or endure salt and corrosion resistance, have good tenacity and strength, its serve as work oneself model the dry time ≤2.5h of priming paint, dry rate is rapid, can rise to fight salt very well, fight alkaline with anticorrosive action, suitable scope is wide, have avirulent, low VOC and the advantage that do not contain heavy metal.

The data shows, inferior person only then built 1998, hand in place at was in 2017 advocate board appear on the market, already built heat preservation of body of wall of coating of a function building, building to decorate unifinication material, building at present energy-saving insulation material, waterproof and its use a system 4 greatly advocate business Wu and inferior person SOK, inferior person new retail the business that mode of Wu of two great undertaking expands in coordination. Current, the group is built in the whole nation 10 produce base greatly.
