Problems solved by technology

[0004] In order to solve the problem that the existing waterproof adhesive will deform with the deformation of the base material, and then produce cracks, causing the waterproof failure of the deformed part
It can absorb the stress transmitted by the base material and prevent the waterproof layer from cracking. When the base material deforms and stretches the waterproof layer, the creep material absorbs the stress from the base layer and deforms with the deformation of

Abstract

The invention discloses a high-performance asphalt sealing waterproof anti-corrosion adhesive and a preparation method thereof, belongs to the technical field of chemical engineering, and solves the problem that an existing waterproof adhesive deforms along with the deformation of a base material to generate cracks to cause a deformed part is invalid in waterproofing. The high-performance asphaltsealing waterproof anti-corrosion adhesive is prepared from the following components in parts by weight: 30-60 parts of petroleum asphalt, 20-30 parts of a modifier, 5-10 parts of a softener, 3-5 parts of a cross-linking agent, 1-2 parts of a catalyst, 3-6 parts of a solubilizer and 20-40 parts of a micro-expansion filler. Compared with a traditional waterproof adhesive, the high-performance asphalt sealing waterproof anti-corrosion adhesive is prepared by using the modifier, the cross-linking agent and the catalyst for crosslinking modification of the petroleum asphalt, the melting temperature is increased while the glass transition temperature is reduced, therefore construction can be carried out at normal temperature, and in a temperature range of 30-80 DEG C, the high-performance asphalt sealing waterproof anti-corrosion adhesive can keep good flexible working performance, high bonding property, high anti-permeability, and good creep property, and has aging-resistance, acid and alkali resistance and excellent self-repairing function.

Description

technical field [0001] The invention relates to the technical field of chemical industry, and more specifically relates to a high-performance asphalt sealing, waterproof and anti-corrosion adhesive and a preparation method thereof. Background technique [0002] Waterproof adhesives are frequently used in municipal engineering, subway tunnels, dams, pools, road bridges, roofs, toilets, underground and other parts for waterproofing and joint filling and bonding. [0003] However, the existing waterproof adhesive will deform along with the deformation of the base material, and then generate cracks, resulting in the problem of waterproof failure of the deformed part. At the same time, the production process of the existing sealing and waterproof adhesive is complicated, and it is difficult to simultaneously improve the high temperature resistance, low temperature flexibility and tear strength. Contents of the invention [0004] In order to solve the problem that the existing ...
