Embodiment Construction

[0004] The preparation process of the preferred embodiment of the present invention will be described in detail below. First pour 200KG of gray cement into the feed port, turn on the switch of the hoist, so that the cement automatically enters the mixer, and then add 40KG of vinyl acetate / ethylene copolymer powder, 2.5KG of methyl cellulose and 1.25KG of polyethylene Alcohol is thrown in, then when 150KG gray cement, 150KG dry fine sand and 450KG quartz sand are added to the mixer, the mixer is started at the same time, and 10KG gray cement is weighed and put into it. Stir for another 5 minutes after the feeding is completed, and the stirring time is 10-15 minutes in total, then take a sample, and pack it after passing the preliminary test. Among them, vinyl acetate / ethylene copolymer rubber powder is a product of Weikai Company. It has anti-saponification performance, can be redispersed in water, and can improve adhesion, flexural strength, plasticity, wear resistance, crack ...

Abstract

A multifunctional flexible powder adhesive is prepared from cement No.525, dried fine sand, quartz sand, copolymer and methyl cellulose. Its advantages are high elasticity and high antiageing performance.

Description

Technical field: [0001] The invention relates to an adhesive, in particular to an adhesive used for painting, plastering and interface treatment of various material interfaces in construction engineering. Background technique: [0002] At present, in the reconstruction of old buildings and new buildings, the combination of various deformation materials is often encountered, such as the paste of rigid concrete facilities and thermal insulation materials with large deformation, and the rigid ceramic tiles are pasted on the surface of fiberboard, such as using organic adhesives. Paste, easy to age and brittle. There will be more and more problems like this with the development of the construction market, and there is an urgent desire for good materials to come out. Invention content: [0003] The technical problem to be solved by the invention is to provide a multifunctional flexible powder adhesive that can effectively overcome the above defects and has fire resistance, hig...
