Polyolefin nano-alloy multifunctional self-adhesive waterproof coiled material capable of reflecting, insulating, purifying air and homogenizing

Abstract

The invention relates to a polyolefin nano-alloy multifunctional self-adhesive waterproof coiled material capable of reflecting, insulating, purifying air and homogenizing, and aims to solve the problems of no environmental protection and no durability, and the coiled material is prepared from the following materials: chlorinated polyethylene powder, low-density polyethylene, polypropylene, high-density polyethylene, metallocene polyethylene, ethylene propylene diene monomer and polyurethane. The preparation method comprises the following steps: mixing, granulating, mixing, casting, and coating the bottom surface with glue and film. In the step of mixing, the chlorinated polyethylene powder, the low-density polyethylene and the polypropylene are mixed by a preheating mixer, the uniformly mixed surface activation modifier and the nano photocatalyst are added for mixing, other auxiliaries except the plasticizer are added for mixing, and finally the plasticizer is added for mixing; and the mixing step is to mix the granules prepared by granulation with high density polyethylene, metallocene polyethylene, ethylene propylene diene monomer, polyurethane and ethylene-vinyl acetate copolymer by using a mixing machine. The waterproof, reflective, heat-insulating, air-purifying, self-adhesive, durable and comprehensive properties are good, and particularly, the waterproof, reflective, heat-insulating, air-purifying, reflective and heat-insulating coiled material is light and convenient to construct, and the durable property can well meet the requirements of modern buildings.

Description

technical field [0001] The invention relates to a self-adhesive waterproof coiled material, in particular to a multifunctional self-adhesive waterproof coiled material with polyolefin nano-alloy reflection, heat insulation, air purification and homogeneity. Background technique [0002] Building waterproofing is an important industry related to the national economy and people's livelihood. Building waterproofing is related to building safety and life, and it is related to people's livelihood and well-being. At present, my country's waterproof membranes are still based on asphalt-based or modified asphalt, with a single waterproof function. However, asphalt is a brown-black organic gelatinous substance, including natural asphalt, petroleum asphalt, shale asphalt and coal tar asphalt. The main components are asphaltene and resin, followed by high boiling point mineral oil and a small amount of oxygen, sulfur and chlorine compounds. Glossy, liquid, semi-solid or solid state, ...

AI Technical Summary

Problems solved by technology

However, there are problems with polymer waterproof membranes: the function of the product is simplistic, and it can only be waterproof; the multi-functional membrane is multi-layer composite, not homogeneous; most waterproof materials are welded, and welding will pollute the air, and once damaged, it will Flooding water; basically no function to purify the air, etc.

However, in terms of comprehensive performance such as waterproof, reflection, heat insulation, air purification, self-adhesive, durability, etc., especially in terms of air purification reflection, heat insulation and convenient construction and durability, it cannot meet the needs of modern buildings.
