Problems solved by technology

[0003] The existing asphalt composite waterproof membrane is used in a high temperature environment. Due to its poor high temperature resistance, its performance is reduced, and it will be exposed to light during use. Under the light condition, the asphalt composite waterproof membrane will undergo photochemical reactions. , so that its own performance is reduced, which in turn reduces the service life

Abstract

The invention discloses a high-temperature-resistant asphalt composite waterproof coiled material and a preparation method thereof. The asphalt composite waterproof coiled material is prepared from the following raw materials in parts by weight: 40-50 parts of matrix asphalt, 10-13 parts of base oil, 10-15 parts of heat-resistant rubber and 20-30 parts of an anti-aging filler. The heat-resistant rubber and the anti-aging filler are prepared in the preparation process, and the heat-resistant rubber is crosslinked with asphalt, so the heat resistance of the heat-resistant rubber is greatly improved, and when the composite material is prepared from the heat-resistant rubber and the asphalt, the heat resistance of the asphalt is greatly improved, and the asphalt cannot be separated from the body along with the use of the waterproof coiled material; the anti-aging filler can shield ultraviolet rays, so the waterproof coiled material does not generate photochemical reaction under illumination, carboxyl and hydroxyl on the modified carbon fibers enable crosslinking of the modified carbon fibers and asphalt to be firmer, and the situation that after the waterproof coiled material is used for a long time, the anti-aging filler is separated from a body, and the anti-aging effect cannot be achieved is prevented; and due to the use of the carbon fibers, the service life of the waterproof roll is prolonged.

Description

technical field [0001] The invention belongs to the technical field of waterproof material preparation, and in particular relates to a high-temperature-resistant asphalt composite waterproof coiled material and a preparation method thereof. Background technique [0002] The existing waterproof membrane products on the market are mainly composed of three series, modified bitumen waterproof material, polymer plastic waterproof sheet and synthetic rubber waterproof membrane. The modified asphalt waterproofing membrane is made of rubber modified petroleum asphalt as the impregnated covering layer, made of polyester fiber non-woven fabric, jute cloth, glass fiber mat, etc. , ingredients, co-melting, impregnation, composite molding, curling and other processes. Modified bitumen waterproof membrane can be divided into two categories according to the tire base: polyester tire and glass fiber tire; modified bitumen waterproof membrane is widely used It is suitable for waterproofing ...
