Abstract

A water-soluble high-molecular adhesive powder is proportionally prepared from polyvinyl alcohol, vinyl polyoxide and hydroxypropyl methylcellulose through proportional mixing. It is applied by dissolving it in water in ratio of 1:300 to obtain liquid adhesive. Its advantages are high solubility and dissolving speed, high viscosity and stability.

Description

technical field [0001] The invention belongs to concrete admixtures, in particular to concrete bonding admixtures. Background technique [0002] The traditional concrete bonding admixture mainly uses 107 glue, because 107 glue will volatilize formaldehyde when used, which seriously damages human health, and 107 glue is very inconvenient to carry and transport as a liquid, which affects the scope of use. Contents of the invention [0003] The object of the present invention is to provide a polymer water-soluble rubber powder that does not contain formaldehyde and is convenient to carry and transport. [0004] The invention is composed of 1 part of polyvinyl alcohol, 1-5 parts of polyethylene oxide and 5 parts of hydroxypropyl methylcellulose. During production, it is mixed evenly and packaged by a closed mixer. [0005] The above-mentioned polymer water-soluble rubber powder is white, non-toxic and tasteless, and does not contain any volatile harmful substances. It is an ...
