A kind of straw ash thermal insulation mortar and the method of using it to prepare thermal insulation board

Abstract

The invention discloses straw ash insulating mortar. The mortar comprises the following components in parts by weight: 70-130 parts of straw ash, 10-130 parts of coal ash, 150-170 parts of cement, 1-2 parts of a water reducing agent, 2-4 parts of HPMC, 10-16 parts of gelatin powder, 1-3 parts of polypropylene chopped fiber, 2-4 parts of wood fibers and 0-60 parts of calcined coal gangue. The invention also discloses a method for preparing a straw ash insulating plate, which comprises the steps of mixing and stirring the components in the straw ash insulating mortar; and making a plate and forming by virtue of a plate making die and a forming press.

Description

technical field [0001] The invention relates to a straw ash thermal insulation mortar; the invention also relates to a method for preparing a thermal insulation board by utilizing the straw ash thermal insulation mortar, which belongs to the application of building materials. Background technique [0002] At present, the cause of building energy conservation is developing rapidly, and external wall insulation technology has begun to be widely used. However, the existing external wall insulation materials have more or less certain defects, such as: polypropylene particles, EPS (XPS) insulation boards are flammable, vitrified beads, cement foam boards, etc. are prone to cracking, falling off, cracks, etc. and other quality issues. Moreover, the existing external wall insulation materials have complicated technological process, high labor intensity and high project cost during engineering construction. [0003] Therefore, a new technical solution is needed to solve the above ...
