Problems solved by technology

[0003] In order to solve the problem that the existing two types of waterproof coiled materials for bridge engineering basically use high-pressure polyethylene to modify chlorinated polyethylene as the base of the waterproof coiled material, which cannot fully meet the performance indicators of the product
If thermoplastic rubber SBS or thermoplastic elastomer TPE is used as the main material, the formula cost is too high, and a modified chlorinated polyethylene waterproof membrane and its preparation method are provided.

Abstract

The invention relates to a waterproof product containing chlorinated polyethylene, in particular to a waterproof roll sheet containing chlorinated polyethylene and a preparation method, which solve the problem that the waterproof roll sheet in the prior art has low performance index and high formula cost. The waterproof product containing chlorinated polyethylene is prepared by the following steps: mixing and stirring an ethylene-octylene copolymer, the chlorinated polyethylene, linear high-pressure polyethylene, a filler intensifier, a soften plasticizer, phenol antioxidants, a heat stabilizer, a lubricating agent and light stabilizer; pelleting the raw materials with a plastics processing mill, a double-roller mill and a pelleter in sequence; feeding granules into a single screw extruder for extruding and forming by a die; and feeding formed materials into a three-roller cooling coining mill for rolling to form the waterproof roll sheet. The invention not only retains unique softness, extensibility and rebound elasticity of rubber, but also retains high tensile breaking strength of LLDPE (Linear Low Density Polyethylene); the whole sheet has good softness, glancing flatness and planeness; performance indexes exceed the national standard and relative standard of ministry of railways; the ageing resisting performance, physical performance and processing performance are excellent; and the production cost is low.

Description

technical field [0001] The invention relates to a waterproof product containing chlorinated polyethylene, in particular to a waterproof coiled material containing chlorinated polyethylene and a preparation method thereof. Background technique [0002] At present, the N-type (non-composite layer membrane) and L-type (double-sided composite non-woven fabric) waterproof membranes for bridges produced by various manufacturers basically use high-pressure polyethylene or linear high-pressure polyethylene to modify chlorinated polyethylene. Do waterproof membrane substrate. Although the formulas and processes of various manufacturers are different, there are great defects; (1) if high-pressure polyethylene or linear high-pressure polyethylene is used as the main body, although various mechanical properties can reach the relevant standards of the Ministry of Railways, but, The softness, flatness and resilience of the product are far from meeting the requirements of construction. B...
