Embodiment 1

[0007] Embodiment 1, an acid rain-resistant CPE waterproof membrane is made of the following raw materials in weight ratio: chlorinated polyethylene 50%, light calcium carbonate 25%, silicon dioxide 7%, talcum powder 6%, carbon black 4%.

[0008] The production adopts a high-efficiency conical twin-screw extruder and introduces a microcomputer control system, which can scientifically and accurately control the process temperature and roller speed, so that the appearance quality of the product can achieve the best effect, and at the same time greatly improve the physical and mechanical performance indicators of the product. It overcomes the problems of air bubbles, scars and cavities in the coil produced by the previous equipment.

Embodiment 2

[0009] Embodiment 2, an acid rain resistant CPE waterproof membrane is made of the following raw materials in weight ratio: chlorinated polyethylene 70%, light calcium carbonate 15%, silicon dioxide 12%, talcum powder 2%, carbon black 7%.

Embodiment 3

[0010] Embodiment 3, an acid rain resistant CPE waterproof membrane is made of the following raw materials in weight ratio: chlorinated polyethylene 60%, light calcium carbonate 20%, silicon dioxide 10%, talcum powder 5%, carbon black 5%.

Abstract

The invention relates to a waterproof material, in particular to an acid rain resistant CPE waterproof coiled material. The material solves the waterproof problem of buildings in an acid rain environment. The material is prepared from raw materials with the following proportions by weight: 50-70 percent of chlorinated polyethylene, 15-25 percent of light calcium carbonate, 7-12 percent of silicon dioxide, 2-6 percent of talcum powder and 4-7 percent of carbon black. The relative change rate of tensile strength is -5 percent in vertical direction and -4 percent in horizontal direction and the relative change rate of elongation at break is +2 percent in vertical direction and +2 percent in horizontal direction. Compared with domestic similar products, the coiled material has the advantages of high strength, corrosion resistance, acid-base resistance, high and low temperature resistance, environmental protection, no pollution, convenience for construction, wide application range and the like.

Description

technical field [0001] The invention relates to a waterproof material, in particular to an acid rain-resistant CPE waterproof coiled material. Background technique [0002] Waterproofing is one of the important functions of all kinds of buildings. Therefore, appropriate waterproofing technology should be adopted in building construction to ensure the waterproof performance of buildings. Therefore, the quality of waterproof materials directly determines the waterproof effect of buildings. At present, there are many problems in waterproofing in my country's construction industry, and the problem of building leakage is quite serious. Especially in recent years due to rapid industrial development and serious air pollution, acid rain has become more and more frequent in some areas. Acid rain has caused serious corrosion to buildings, bridges and other facilities, and traditional waterproof measures are difficult to completely solve this problem. At present, more than 80% of t...
