Adhesive powder for sticking waterproof rolls

Abstract

The invention discloses adhesive powder for sticking waterproof rolls. The adhesive powder is prepared from the following components in parts by weight: 90-100 parts of redispersible latex powder, 1-2 parts of cellulose ether, 2-3 parts of a water repellent, 0.05-0.15 part of defoaming powder, 0.05-0.15 part of a dispersing agent and 1.5-2.5 parts of a filling agent. The invention further discloses a construction method of the adhesive powder for sticking waterproof rolls. The adhesive powder is mixed with water and cement according to a ratio of 1:40:50, and the mixture can be directly coated on concrete or base layers to directly stick waterproof rolls. The adhesive powder disclosed by the invention has the advantages of high sticking strength, good adhesive force and good water retention and water resistance performance, is non-toxic and odorless, is environment-friendly, can be used for sticking various macromolecule waterproof rolls and is simple and convenient in construction, and the comprehensive cost is reduced.

Description

technical field [0001] The invention relates to the technical field of coiled material rubber powder, in particular to a paste waterproof coiled material rubber powder, which belongs to the technical field of building materials. Background technique [0002] At present, the existing PVC, EPDM and other waterproof membranes are all pasted with tire adhesives; the modified asphalt waterproof membranes are pasted by hot melt: use liquefied gas to pass through the spray gun, and heat the reverse side of the membrane for 110°C. Temperature ~ 130 degrees, let the coiled material melt and stick to the base layer. [0003] The above methods all have the defects that the paste is not dense and easy to hollow, which affects the waterproof quality. Moreover, the work intensity of the construction is high and the cost is high. Especially the hot-melt paste has hidden safety hazards, and the construction is quite inconvenient. Contents of the invention [0004] The purpose of the pres...
