Problems solved by technology

[0004] At present, there are many heat-proof and thermal insulation materials based on polyphenylene particles in the domestic market, but most of them do not have waterproof and moisture-proof functions and must be used in conjunction with other waterproof materials. This will not only increase the cost, but also increase the complexity of construction. sex

Abstract

An insulation material consists of A composition and B composition as A composition is a mixed paste prepared from hydrophobic processed packing, polyolefin sort, acrylic acid series, polyurethane series, 1-4 type of high polymer gelled material of epoxy series and assistants as well as B composition is prepared from cement foamed polystyrene, foamed polyurethane and one any type of granule material from polyolefin series. A composition is mixed with B composition as per ratio of 45-70 / 50-20 by weight with adding certain amount of water under agitation when they are to be used.

Description

technical field [0001] The invention relates to building materials, in particular to a waterproof heat-insulating material mainly used on the outside or inside of building enclosure structures. Background technique [0002] General heat insulation materials use expanded polystyrene or other porous materials, which do not have waterproof function, and their heat insulation effect will drop sharply after absorbing water and moisture, because their own compressive strength and shrinkage resistance are not enough Therefore, under the changing natural environment, it will not be able to resist the deformation of the wall and the cracks caused by the shrinkage of the mortar itself over time, which will greatly reduce its heat insulation effect. [0003] Although the traditional heat insulation materials in the domestic market have good heat insulation effect, they are easy to absorb moisture and water because they do not have waterproof function. ,polluted environment.
