Embodiment 1
[0038] According to the proportioning in parts by mass, get 51 parts of bisphenol A type epoxy resin, 15 parts of methacrylic acid, 33 parts of styrene, 0.85 part of benzoquinone, 0.15 part of benzyldimethylamine; Bisphenol A epoxy resin, Put benzyldimethylamine and hydroquinone into the reaction kettle, vacuumize, stir and heat up, and control the temperature at 120°C to 140°C for 3 hours until the acid value drops below 20mgKOH / g; cool the reaction product to Below 110°C, add styrene to dilute, lower the temperature to room temperature, filter and stir evenly to obtain vinyl ester resin. Take 50 parts of p-phenylene unsaturated polyester resin and 50 parts of vinyl ester resin and stir evenly to prepare vinyl ester resin mixed resin for later use. Used in Examples 2-4 below.
[0057] N, N-diethylaniline: 0.3% Aluminum hydroxide: 30%
[0058] Organic bentonite: 1.6%
[0059] Aluminum hydroxide: 40%

Abstract
The invention discloses a vinylester resin stone adhesive and a preparation method thereof. The adhesive consists of a component A and a component B, and can be used by simply mixing the component A and the component B in a mass ratio of 100:2-3, wherein the component A consists of a mixed resin of vinylester resin, a filler, a thickener, a pigment, a defoaming agent, a coupling agent, a promoter and a polymerization inhibitor; and the component B consists of a hyperoxide curing agent, a plasticizer and a filler. The adhesive is suitable for adhering stone for high-rise buildings and metal, or paving stone materials such as marble and ceramic tile, making patterns with stone materials, jointing the stone materials and stopping holes in the stone materials. The production cost of the adhesive is low, and the adhesion force of the adhesive is higher than that of common marble adhesive; the cured shrinkage and deformation rate of the adhesive is low, the heat resistance and corrosion resistance of the adhesive are high; the manufacturability of the operation of the method is high, the gelation time and setting time of the adhesive in a low-temperature and water-containing environment are short, and the adhesive can be used in some damp and highly-corrosive environments. The adhesive is an upgraded substitute for marble adhesive and can replace part of substituted double-component epoxy adhesive.
Description
technical field [0001] The invention relates to a vinyl ester resin stone adhesive and a preparation method thereof, which is mainly used for bonding and fixing stone and metal, or laying, docking, mosaicing and repairing broken stones such as ceramic tiles and marble. Background technique [0002] High-rise buildings have high space utilization and strong visual impact. They are an important building type in people's lives, and fully reflect the impact of building materials on people's living standards. Therefore, people pay more attention to the development of the high-rise building industry, and the application of main decoration materials such as adhesives has always been the focus of research and discussion. [0003] High-rise building stone adhesives mainly include marble adhesives and two-component epoxy adhesives. The cost of marble glue is low and the price is cheap; the curing time is short, which can play the role of rapid positioning, repair and bonding, without...
