Abstract
The invention discloses a novel environmental-protection adhesive for buildings, which is mainly characterized in that vinyl acetate is used as a polymerization monomer; crylic acid, butyl acrylate and styrene are used as functional monomers; polyvinyl alcohol (PVA) and vinyl acetateethylene emulsion (VAE) are used as protective colloids; nano silicon micro powder is used as an anti-caking agent; and ethyl benzoate and 0# colloid crystal are used as modifiers. The main monomer and the functional monomers are prepared into emulsion through multi-element copolymerization; the protective colloids, the anti-caking agent and the modifiers are added to prepare powder through spray drying. The raw material formula comprises the following components: 8-10 percent of polyvinyl alcohol, 0.3-0.5 percent of polyoxyethylene octylphenol ether-10 (OP-10) emulsifying agent, 0.1-0.15 percent of ammonium persulfate, 25-30 percent of vinyl acetate, 0.05-0.1 percent of sodium hydroxide, 20-25 percent of vinyl versatate, 2-2.5 percent of butyl acrylate, 3-5 percent of ethyl acrylate, 0.05-0.15 percent of silicone, 3-5 percent of styrene, 30-40 percent of ethyl acrylate-acetic acid copolymerization emulsion, 8-12 percent of ethyl benzoate, 10-15 percent of silicon micro powder and 5-10 percent of 0# colloid crystal. The novel environmental-protection adhesive for the buildings is added to interior and exterior wall putty powder proportionally, and thereby, the characteristic of the putty powder can be improved. The novel environmental-protection adhesive for the buildings mainly has obvious effects of improving anti-caking performance, bonding force, waterproofness, improving low-temperature service performance, enhancing hardness and preventing hollowing, cracking and dropping.
Description
technical field [0001] The invention relates to a construction adhesive formula and a preparation method thereof, in particular to a novel environmentally friendly construction adhesive added to interior wall or exterior wall putty powder and a preparation method thereof. Background technique [0002] With the rapid development of the construction industry, various building decoration materials have sprung up to meet the consumption needs of consumers at different levels. Putty powder is a necessary material for home decoration. Ordinary putty powder has many disadvantages such as easy to fall off, not resistant to water, poor adhesion, poor crack resistance, etc., which cannot achieve the construction effect and has a small scope of application. Contents of the invention [0003] The object of the present invention is to provide a novel environmentally friendly construction adhesive for improving and increasing the performance of ordinary putty powder and its production m...
