Embodiment Construction

[0289] The present invention is described in detail below in conjunction with embodiment

[0290] (1) The specific components and weight percentages of component A are as follows:

[0291]

[0292]

[0293] The modified unsaturated polyester resin is prepared by the following method: 1) maleic anhydride is hydrolyzed to generate maleic acid; 2) dicyclopentadiene is mixed with maleic acid at 110-140°C Addition reaction occurs at the carboxyl group to generate dicyclopentadiene-maleic acid monoester; 3) dicyclopentadiene-maleic acid monoester is esterified as monobasic unsaturated acid and propylene glycol under esterification catalyst Polycondensation reaction to obtain dicyclopentadiene-terminated polyester; 4) dicyclopentadiene-terminated polyester, diluted with methyl methacrylate, to obtain dicyclopentadiene-modified unsaturated polyester resin;

[0294] Wherein step 3) dicyclopentadiene is used as a monobasic unsaturated acid and propylene glycol under the methanesu...

Abstract

The invention discloses a polymer emulsion interfacial agent for treating a building wall and a preparation method of the polymer emulsion interfacial agent. The polymer emulsion interfacial agent comprises a component A and a component B, which are mixed at the weight ratio of 1:1 during use, wherein the component A comprises the concrete components as follows: hydroxyethyl cellulose, a dispersing agent, quartz powder, a styrene-acrylate polymer emulsion, rare-earth nanometer Ce-ATO modified acrylic resin, an anticorrosive agent, a mildewproof agent, a multifunctional additive, a thickening agent, a defoaming agent and a coalescing agent, water and unsaturated polyester resin; and the component B comprises the following components: wollastonite powder, quartz powder, quartz sand, cerium phosphate, a titanate coupling agent, cobalt naphthenate and methyl ethyl ketone peroxide. The polymer emulsion interfacial agent has the characteristics of simple preparation process, high adhesive force, wear resistance, good sealing property and the like and can be well used on a smooth-surface substrate.

Description

technical field [0001] The invention relates to a polymer emulsion interface agent for building wall surface treatment and a preparation method thereof. Background technique [0002] One: the single-component product composition of prior art: [0003] Product composition: single component (powder); product ingredients: black cement additives, a small amount of redispersible latex powder, quartz sand; production process: pour the powder in the product ingredients into a dry powder mixer and stir evenly. Product color: gray or black; construction method: add water to the product, disperse it evenly with a hand-held disperser, and apply it on the substrate in batches; main purpose: scrape the surface of the external wall insulation brick together to form the interface It is easy to bond the external wall putty. Product Weaknesses: 1) Poor adhesion, can not be used on smooth surface substrates. 2) poor sealing. [0004] Two: the two-component product composition of prior art...
