One, definition 1, Epoxy resin(Epoxy Resin) it is generally refer to contain two or oxygen of two above annulus base, with adipose a group of things with common features, fat annulus a group of things with common features or the organic compound such as scent a group of things with common features is framework and can carry ring the high polymer that reaction of oxygen radical group forms useful hot solidify production is low get together body (Oligomer) . It is zero hour when N of degree of polymerization, the oxidation is annulus that say closes matter, abbreviation annulus oxide (Epoxide) . Although colophony of these quality of small opposite element do not satisfy strict definition completely but because have the major attribute of epoxy resin,also do not add discriminative ground a general designation to be epoxy resin when appellation. Typical epoxy resin structure is as follows type. 2, annulus oxygen base the character that is epoxy resin base round, more or less is its content this kind of colophony attachs most importance to wanted quota. Describe annulus oxygen radical content has the following kinds of different notation: Equivalent of ⑴ annulus oxygen: It is to point to the mass that contains 1mol epoxy resin, quality of small opposite element (the element is measured) the annulus oxygen equivalent of epoxy resin is 175 ～ 200g/mol, increase annulus as what the element measures Duan Yue grows the catenary between oxygen radical, the annulus oxygen equivalent that so high polymer measures epoxy resin is corresponding tall. ⑵ annulus oxygen is worth: The place in every 100g colophony contains annulus the quantity of the material of oxygen radical (rub Er) . This kind states what the method is helpful for solidify agent dosage is metric the expression with dosage. Because the meaning of solidify agent dosage is the affiliation of agent of the solidify in every 100g epoxy resin,measure (abbreviate of Part Perhundred Of Resin becomes Phr) . Our country uses annulus oxygen to be worth this one physical quantity. Oxygen of annulus of =100/ of annulus oxygen equivalent is worth 3, the definition viscosity of viscosity: When the liquid is flowing, arise between its element inside the property of attrition, call liquid stickiness, the size of stickiness indicates with viscosity, it is to use the obstruction factor related token liquid property. Viscosity unit has two kinds: 1, li berth (second of handkerchief of Cps) 2, fine long hair (M·pas) 1 li berth (Cps) second of handkerchief of = 1 fine long hair (M·pas) 2, sort and function 1, double phenolic A epoxy resin: Double phenolic A (namely 2 phenol base propane) model epoxy resin namely 2 phenol base aether of propane shrink glycerine.
