High-temperature resistant environment-friendly glue powder

Abstract

The invention discloses high-temperature resistant environment-friendly glue powder which consists of the following components in parts by weight: 40-60 parts of hydroxymethyl cellulose, 5-10 parts of corn starch, 1-5 parts of nano calcium carbonate, 5-10 parts of latex powder, 10-20 parts of shell powder, 15-20 parts of fly ash, 5-10 parts of viscose reinforcing agent and 3-5 parts of sodium benzoate. After the glue powder disclosed by the invention is dissolved in water, the high-molecular material and auxiliary thereof are adhered to the light calcium carbonate to form a high-performance glue binder; and the coating prepared from the glue powder has the advantages of convenience in construction, no urinary stream, good leveling property, no rolling and fast film formation and avoids the phenomena of rolling and falling in a high-temperature state.

Description

technical field [0001] The invention relates to a high-temperature-resistant environment-friendly glue powder. Background technique [0002] The glue used in the construction industry is different from ordinary glue, which requires high adhesion and a long enough sticky time. There are two production methods for construction glue currently used in the market. One is that the manufacturer directly packs the liquid produced by chemical materials such as polyvinyl alcohol and acrylamide and puts it on the market; the other is that the manufacturer puts PVA, EVA, CMC, etc. High molecular polymer rubber powder is processed into construction glue and put on the market after packaging. The packaging required by these two production methods is large and not energy-saving enough; the cost of storage and transportation on the market is high and not economical; the products produced are inconvenient to use; the glue produced by them contains toxic substances such as formaldehyde, ammo...

Problems solved by technology

But the construction glue powder (solid glue) of prior art, except that its adhesion ability is different, also generally has the shortcoming of polluting the environment, and some long-term contact can cause damage to the health of construction workers.
