Cohesive glue for flexible decorative tile and manufacturing method thereof

Abstract

The invention relates to cohesive glue for a flexible decorative tile and a manufacturing method thereof; the cohesive glue is composed of the following raw materials by weight proportion: 0.3-1.5 percent of water-retaining agents, 28-48 percent of water, 0.3-2 percent of thickeners, 48-68 percent of polymer latex, 0-0.35 percent of ultra-violet absorber, 0-0.42 percent of antioxidant, and 0.7-4.2 percent of film-forming additives; the manufacturing method is that: 1-3 percent of the water-retaining agents, 93-97 percent of water and 1-4 percent of the thickeners are mixed to prepare water-holding thickening liquid for spare, and then 94-98 percent of the polymer latex, 0-0.5 percent of the ultra-violet absorber, 0-0.6 percent of the antioxidant and 1-6 percent of the film-forming additives are mixed to prepare polymer film-formation weather-proofing modified liquid for spare, and 30-50 percent of the water-holding thickening liquid and the polymer film-formation weather-proofing modified liquid are formulated to prepare the cohesive glue for the flexible decorative tile. The cohesive glue has the advantages of no taste, no toxicity, high first sticking intensity, low volume weight and rapid construction speed.

Description

Technical field [0001] The invention relates to a bonding glue and a manufacturing method thereof, in particular to a bonding glue used for bonding flexible decorative surface tiles of building exterior walls and a manufacturing method thereof. Background technique [0002] Traditional external wall flexible decorative tile adhesives are made of cement mortar or polymer cement mortar, and they often have the following common problems when applied to external walls: [0003] 1. The initial bonding strength is low, and it is easy to fall off; 2. The bonding mortar will pollute the facing tiles during construction and affect the appearance; 3. The construction speed of tiling is slow, which increases the construction cost; 4. Because of the large capacity of the bonding material , A large amount (dosage 4Kg / m 2 ), thus adding the load of the gravitational moment to the external wall insulation material; 5. The bonding material is a rigid material, and the temperature change coefficien...

Problems solved by technology

[0003] 1. The initial adhesive strength is low, and it is easy to fall off; 2. The adhesive mortar will pollute the facing brick during construction and affect the appearance; 3. The construction speed of tiling is slow, thereby increasing the construction cost; 4. Due to the large volume of the adhesive material , more dosage (dosage 4Kg / m 2 ), thus increasing the load of the gravitational moment to the external thermal insulation material of the exterior wall; 5. The bonding material is a rigid material, and the temperature variation coefficient of the material is very different from that of the flexible decorative brick, and its bonding interface is prone to occur under frequent temperature changes. Displacement, causing the flexible decorative tiles to fall off
