Abstract

The invention relates to a waterproof material for a construction field, in particular to an inorganic waterproof and temperature preservation material with composite layers; the invention solves the problems of poor weather resistance , poor waterproof performance, easy aging, short service life, simple function and others in the prior inorganic waterproof material; the invention comprises material A as a waterproof and temperature preservation layers and material B as a cushion layers; material A comprises cement, waterproof powders and expansive agent, and material B comprises cement, vermiculite, waste plastic and glass fibers; material B is added with water, stirred into mud and coated on the surface of an object; then material A is added with proper amount of water, stirred into mud, and coated on the cushion layers. The inorganic waterproof material integrates waterproof, temperature preservation and heat insulation, with excellent waterproof effect and temperature preservation; the invention has the advantages of strong bond force, good anti-permeability performance, high temperature resistance, low temperature resistance, strong weather resistance, etc.; each performance index of the material exceeds the national standard, and the service life up to 50 years; more importantly, the waste plastic is utilized to realize the targets of pollution treatment, environment protection and cost saving.

Description

technical field [0001] The invention relates to a waterproof material used in the construction field, in particular to a composite layer inorganic waterproof and thermal insulation material. Background technique [0002] It is known that asphalt paper or asphalt is used for waterproofing of industrial and civil buildings directly on the surface to be waterproofed. Cracks lead to problems such as poor waterproofness and short life. Subsequently, people developed a variety of new waterproof materials, such as asphalt-based waterproof materials, polymer-modified asphalt-based waterproof materials, polyurethane waterproof materials and other organic waterproof materials. It has a greater impact, so it is not very ideal in terms of weather resistance, mechanical properties, waterproof performance and durability; second, it is easy to age, has a short service life, is not easy to decompose, pollutes the environment, and has a high cost; third, it has a single function. It only h...
