Problems solved by technology

[0002] There are several types of asphalt waterproofing membranes on the market, among which non-self-adhesive modified bitumen waterproofing membranes require additional steps when used in construction, while self-adhesive modified bitumen waterproofing membranes can be more easily applied on the required On waterproof walls, at present in China, the construction technical characteristics of self-adhesive cold construction waterproof membranes have been highly recognized, but due to the shortcomings of its materials, this material has been widely promoted in the market and created resistance, specifically shown in : In order to achieve the self-adhesive performance of the material, some performance indicators of the material itself have to be lowered, such as the heat resistance index, which makes the material cannot be used in high temperature environments, such as exposed roofs in high temperature areas. Secondly, the existing The manufacturing process of self-adhesive modified bitumen waterproofing membrane is relatively high, which is not conducive to market competition. Moreover, its material technical indicators are single, which cannot meet the multi-faceted requirements of the construction industry for waterproofing materials.

Embodiment 1

[0014] (1) Preparation of raw materials: Select suitable tire base for later use, and prepare 90 parts of No. 90 asphalt, 10 parts of No. 10 asphalt, 15 parts of silica gel, 5 parts of PSBR, modified 30 parts of plasticizer, 10 parts of modified PP powder, 8 parts of filler.

[0015] (2) Preparation of modified asphalt waterproof membrane mixture: first heat the No. 90 asphalt and No. 10 asphalt, then mix the raw materials into it according to the proportion and stir for 2.5 hours, then grind for 50 minutes with a colloid mill, and finally stop heating.

[0016] (3) Coating self-adhesive film and isolation film: the self-adhesive film is coated on the upper and lower surfaces of the modified asphalt waterproof coil material mixture by a coating machine, and then the surface of the self-adhesive film is Apply the barrier film.

[0017] (4) Packaging the finished product: the modified asphalt waterproof membrane mixture coated with the self-adhesive film and the isolation film...

Abstract

The invention discloses a manufacturing process of a modified asphalt waterproof coiled material, and relates to the technical field of building material preparation. The manufacturing process comprises four processing steps including preparation of raw materials, preparation of modified asphalt waterproof coiled material mixing materials, coating of a self-sticking rubber film and finished product packaging. The manufacturing process of the modified asphalt waterproof coiled material has the advantages that the produced modified asphalt waterproof coiled material has good self-sticking characteristics; meanwhile, the defects of high manufacturing cost and single technical index in the existing manufacturing technology are overcome; the manufacturing process is applicable to large-scale production; the modified asphalt waterproof coiled material is suitable for being used at high temperature; the multiaspect requirements of the building industry on the waterproof material is better met.
