Abstract

The invention relates to a polymer cement waterproof adhesive applicable for roof, underground building, joint, sealing and bonding. 48kg cements and 52kg quartz sand are added in a mixer in sequence, stirred for 5-10 min and discharged to get 100kg cement color powders; 68kg vinyl acetate-ethylene copolymer emulsion, 14kg methyl methacrylate, 18.5kg water, 0.12kg sodium polycarboxylic acid and 0.13kg poly (dimethylsiloxane) are sequentially put into a reactor with the reaction temperature being 63-68 DEG C, stirred for 1h and discharged and 100kg ivory white liquor material is produced; the powders are poured into the liquor material according to 1:1 weight ratio and the adhesive is obtained after the mixture is evenly stirred. The invention has the advantages of low cost, less application devices, easy operation, no danger, innocuity, excellent adhesion, waterproof property and permeability and being capable of construction in wet base.

Description

technical field [0001] The invention relates to a polymer cement type waterproof adhesive suitable for joints, sealing and bonding of roofs and underground buildings. Background technique [0002] Roof waterproof materials include asphalt and linoleum. Boiling asphalt during construction pollutes the environment. Asphalt is flammable and unsafe, so it is not easy to construct in winter; emulsified asphalt waterproof coatings will break when frozen, deteriorate and fail, and the waterproof effect is poor; PVC waterproof ointment, It needs to be heated when used, and it is easy to catch fire; polyurethane waterproof coating cannot be used on a wet base surface, and its anti-aging performance is poor. Contents of the invention [0003] The object of the present invention is to overcome above-mentioned defect, provide a kind of polymer cement type waterproof adhesive suitable for roofing, underground construction, seam, sealing, bonding. [0004] The technical solution of the...
