Abstract

The invention relates to the technical field of macromolecules, in particular to vinyl resin easily adhered with concrete. The vinyl resin is prepared from the following components in parts by weight: 38 to 41 parts of bisphenol A formaldehyde epoxy resin, 5 to 7 parts of polyurethane modified epoxy resin, 6 to 9 parts of butylated melamine-formaldehyde resin, 5 to 8 parts of methacrylic acid, 16 to 18 parts of acrylic acid, 12 to 15 parts of fumaric acid, 16 to 20 parts of maleic anhydride, 0.5 to 1 part of ethyl triphenyl phosphonium bromide, 0.6 to 0.9 part of hydroquinone, 48 to 50 parts of styrene, 13 to 15 parts of itaconic anhydride, and 3 to 8 parts of viscosity modifier. The prepared vinyl resin has the advantages that the mechanical property is excellent; compared with the traditional vinyl resin, the tensile strength, bending strength and elongation at break are better; after constructing on the concrete surface, the vinyl resin can be adhered with the concrete through the self toughness, and be bonded with silicon oxygen bonds of the concrete after curing, so as to improve the viscosity to the concrete.

Description

technical field [0001] The invention relates to the technical field of macromolecules, in particular to a vinyl resin which is easy to bond with concrete. Background technique [0002] Unsaturated polyester resin is generally a linear polymer compound with ester bonds and unsaturated double bonds formed by polycondensation of unsaturated dibasic acid diols or saturated dibasic acid diols. Usually, the polyesterification and polycondensation reaction is carried out at 190-220°C until the desired acid value (or viscosity) is reached. After the polyesterification and condensation reaction is completed, a certain amount of vinyl monomer is added while it is hot to form a viscous Such a polymer solution is called an unsaturated polyester resin. [0003] So far, the unsaturated polyester (resin) matrix used as composite material matrix at home and abroad is basically phthalic acid type (referred to as orthophthalic type), isophthalic acid type (abbreviated as isophthalic type), b...
