Problems solved by technology

[0002] At present, the existing waterproof roll materials use tire adhesives and hot-melt pasting methods. The existing pasting methods all have the defects of not being densely pasted and easy to hollow, which affects the quality of waterproofing, and the construction work is intensive and costly. It is hot-melt paste and there are safety hazards, and the construction is quite inconvenient

Abstract

An adhesive powder with large adhesive strength and good toughness and for pasting waterproof coils belongs to the technical field of building materials. The adhesive powder comprises 110-120 parts of re-dispersible latex powder, 10-50 parts of water, 5-15 parts of hydroxypropyl methyl cellulose, 0.07-0.10 parts of an antifoaming agent, 5-8 parts of a filler, 0.05-0.15 parts of a bactericide, 5-15 parts of quartz powder and 0.2-0.6 parts of a vinyl acetate-ethylene copolymer. The adhesive powder has the advantages of high pasting strength, high adhesion, good water retention property, good water prevention performance, non-toxicity, tastelessness, greenness and environmental protection, use in pasting of various polymeric waterproof coils, simplicity in construction, and comprehensive cost reduction.

Description

technical field [0001] The invention relates to a component of coiled material rubber powder, in particular to a rubber powder with high bonding strength and good toughness for pasting waterproof coiled materials, and belongs to the technical field of building materials. Background technique [0002] At present, the existing waterproof roll materials use tire adhesives and hot-melt pasting methods. The existing pasting methods all have the defects of not being densely pasted and easy to hollow, which affects the quality of waterproofing, and the construction work is intensive and costly. It is hot-melt paste and there are potential safety hazards, and the construction is quite inconvenient. Contents of the invention [0003] The object of the present invention is to address the above-mentioned deficiencies in the prior art, and provide a glue powder with high adhesive strength and good toughness, which is convenient for construction, and is used for pasting waterproof coil...
