However, problems such as leakage, water permeability, bonding and sealing of buildings have always been the bottlenecks that plague the development of prefabricated buildings.
Although high-end and mid-range sealing materials occupy a relatively high market share, there are more or less problems in their application in prefabricated buildings: 1) Silicone and modified silicone sealing products have good bonding and sealing performance, elasticity and elasticity Good recovery rate, excellent construction performance, strong durability and weather resistance
When the product type is not selected properly, it is easy to cause the problem of poor quality of the prefabricated building, and even cause safety hazards

Abstract
The invention discloses a water-based environment-friendly sealing paste, which relates to the technical field of building waterproofing. Its components include latex, plasticizer and toughening agent, nano functional filler, crystallization masterbatch, glass flakes, bentonite microspheres and water. The product of the present invention has the following comprehensive characteristics: 1) It has the functions of anti-seepage, sealing, waterproof, anti-vibration, sound insulation and heat insulation; 2) Low sag, good construction performance of embedded filling, extrusion injection, scraping coating, and stable storage ; 3) Low permeability to liquid, gas and other media; 4) Can withstand joint displacement and deformation with expansion and contraction movement, and can fully restore its performance and shape after undergoing repeated deformation in the joint; 5) Have sufficient strength , can withstand stress; 6) Stable bonding with different material joint base surfaces, no peeling and degumming, water channeling resistance, and no pollution of substrates; 7) Not excessively softening at high temperatures, not brittle at low temperatures, weather-resistant, No pulverization, cracking or excessive shrinkage; 8) Environmental protection, mildew resistance, and long enough service life.
Description
technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a water-based environment-friendly sealing paste and a production process thereof. Background technique [0002] In today's world, prefabricated buildings are developing rapidly. According to statistics, the proportion of industrialized housing accounts for 80% in Sweden, and more than 70% in the United Kingdom, the United States, and Japan. Domestic prefabricated buildings have entered a period of rapid development. However, problems such as leakage, water permeability, bonding and sealing of buildings have always been the bottlenecks that plague the development of prefabricated buildings. [0003] At present, the sealing paste (glue) products that can be used for prefabricated buildings at home and abroad have formed three series of high-grade sealing materials: silicone and modified silicone, polyurethane, and polysulfide. Sealing materials, as well as the pa...
