Problems solved by technology

Asphalt and its fumes are irritating to the skin and mucous membranes, which will increase the sensitivity of the human body to sunlight and cause acute damage reactions on the skin surface. Long-term exposure to asphalt and its fumes will also lead to the incidence of cancer among workers increased
During the processing of asphalt, asphalt fume will not only threaten the life and health of workers, but also seriously pollute the surrounding environment
[0004] At present, there are few waterproof adhesives on the market that use epoxy resin and epoxy curing agent as the main raw materials, and no waterproof adhesives that are prepared with epoxy resin and epoxy curing agent as the main raw materials and used in the field of building waterproofing have been found.

Abstract

The invention, which relates to the field of building materials, discloses a high-elasticity aging-resistant waterproof adhesive and a preparation method thereof. The waterproof adhesive is prepared by mixing a component A and a component B according to a weight ratio of 1: 1. The component A is prepared from 1200 to 2000 parts of bisphenol A type epoxy resin, 150 parts of reactive diluent, 120 to190 parts of non-reactive diluent, 45 to 80 parts of toughening agent and 120 to 140 parts of fumed silica; and the component B comprises 1200-2000 parts of modified phenolic aldehyde amine, 45-90 parts of a silane coupling agent, 2-6 parts of a defoaming agent, 24-30 parts of a flow stopping agent and 80-190 parts of fumed silica. The waterproof adhesive can reduce the thermal expansion coefficient and the shrinkage rate of a cured product, improve the surface hardness and the compression strength, reduce the heat release temperature in the curing process and play a thickening role, and canbe used in vertical wall surfaces, inclined roofs, ceilings and the like; and the mechanical strength, the elasticity modulus, the thermal aging performance and the weather resistance after curing areoptimized.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a high-elastic anti-aging waterproof glue and a preparation method thereof. Background technique [0002] At present, in roofing membrane waterproofing projects, most projects use asphalt glue as the bonding material for bonding the membrane waterproofing layer. However, many asphalt adhesives on the market have poor heat resistance and toughness, which makes them easy to be melted by heat in summer, and the adhesive force is weakened, which will cause the accident of the coiled material slipping down and flowing, and more seriously, it will cause the entire roofing coiled material to disintegrate; In winter, it is easy to be cold and brittle, so that the roofing membrane will be damaged and cracked under mechanical action, resulting in the loss of waterproof performance. [0003] During the preparation of asphalt rubber, asphalt, the main raw material, needs to be heated and m...
