Background technology
Unsaturated polyester resin, is usually contracted by unsaturated dibasic acid dihydroxylic alcohols or monounsaturated dicarboxylic acid unsaturation dihydroxylic alcohols
The poly- chain macromolecule compound with ester bond and unsaturated double-bond.Generally, polyesterification polycondensation reaction be 190~
220 DEG C are carried out, until reaching expected acid number (or viscosity), after polyesterification contracting reaction terminates, a certain amount of second are added while hot
Alkenyl monomer, is made into sticky liquid, and such polymer solution is referred to as unsaturated polyester resin.
So far, unsaturated polyester (UP) (resin) matrix as matrices of composite material is substantially O-phthalic acid type both at home and abroad
(referred to as adjacent benzene-type), M-phthalic acid type (abbreviation metaphenylene), bisphenol A-type and vinyl ester type, halo unsaturated polyester resin
Deng.
Vinylite is vinyl ester resin, is a kind of epoxy resin and a kind of unsaturated monoacid containing ethylene linkage
Addition reaction product, and diluted through a kind of reactive monomer.Vinylite has good decay resistance, has asphalt mixtures modified by epoxy resin concurrently
The excellent mechanical property of fat and the good characteristic of unsaturated polyester resin normal temperature cure.The resin base made of vinylite is combined
Material, is widely used at aspects such as chemical anticorrosion, flue gas desulfurization, communications and transportation, electronic apparatus.
Traditional vinylite is when with concrete combination, and durability is poor, and firmness is not enough, ultimately results in life-span drop
It is low.
