Solid gum

Abstract

The invention discloses solid gum, which is composed of the following components in parts by weight: 50-70 parts of light nano calcium carbonate, 10-15 parts of hydroxypropyl methyl cellulose, 4-7 parts of ethylene-vinyl acetate copolymerized gum powder, 5-10 parts of fly ash, 10-15 parts of acrylamide, 1-2 parts of calcium formate, 1-2 parts of polycarboxylic acid high-performance water reducing agent, 1-2 parts of lignin, 4-6 parts of silyl water repellent, 3-5 parts of vermiculite powder, 1-3 parts of titanium white powder and 3-5 parts of nano silicon dioxide. The solid gum is prepared in a way that the light nano calcium carbonate is used as a carrier and the hydroxypropyl methyl cellulose, the ethylene-vinyl acetate copolymerized gum powder, the calcium formate, the water reducing agent, the water repellent, the lignin, polyacrylamide, the fly ash and the like are fused to form white powder. The gum powder provided by the invention has the characteristics of no toxicity, no pollution, no odors, no radioactivity and no alkalinity. An applicable temperature range of the solid gum is wide. A paint prepared by the solid gum has the advantages of convenience for construction, no line wetting, good leveling property, no skin curling and fast film formation.

Description

technical field [0001] The invention relates to the field of architectural coatings, in particular to a solid glue. 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...

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.
