Abstract

The invention discloses an insulation board, which is prepared from the following components by mass percentage: 20-30% of straw fragments, 20-25% of inorganic thermal insulation particles and 45-60%of waste plastic. The preparation method of the insulation board is specifically limited. The invention also discloses the preparation method and application of the insulation board. According to theinvention, the straw fragments, inorganic thermal insulation particles and waste plastic are prepared into the insulation board according to a specific ratio and a preparation process; the insulationboard only needs the three raw materials, the straw fragments and the inorganic thermal insulation particles are used for filling and thermal insulation, and the waste plastic is used as a gelatinizing agent besides the thermal insulation effect, and the prepared insulation board has the advantages of light weight, good thermal insulation performance, high structural strength and the like.

Description

technical field [0001] The invention relates to the technical field of thermal insulation boards, in particular to a thermal insulation board prepared from straw, waste plastics and inorganic thermal insulation particles, a preparation method and application thereof. Background technique [0002] Green buildings have become an important part of my country's ecological civilization construction. The goal of my country's green building is vividly defined as "four sections and one environmental protection", that is, energy saving, water saving, land saving, material saving and environmental protection. Energy saving, water saving, land saving, material saving and environmental protection have differences and emphases, and they are interrelated. Among them, material saving contributes the most to environmental protection. Material saving not only requires building materials to have a long service life, but also requires building materials to save resources and reduce environme...
