Embodiment 1

[0054] A building exterior wall thermal insulation material, which is prepared into thermal insulation blocks according to the components indicated in Table 1. The preparation process is: the cementitious material, thermal insulation lightweight aggregate and solid modified additives are put into the slurry mixer Add water and stir evenly, inject it into the mold to form. After the initial setting, the mold can be removed and cured. After reaching a certain strength, it can be cut into blocks according to the design size requirements.

Embodiment 2

[0056] A thermal insulation material for building exterior walls, prepared into thermal insulation blocks according to the components indicated in Table 1, and the preparation process is as in Example 1.

Embodiment 3

[0058] A thermal insulation material for building exterior walls, prepared into thermal insulation blocks according to the components indicated in Table 1, and the preparation process is as in Example 1.

Abstract

The invention discloses a building exterior wall thermal insulation material. The building exterior wall thermal insulation material is formed by mixing a binding material, thermal insulation lightweight aggregate and a property-modifying additive according to the weight ratio of (40-85): (10-55):5. The building exterior wall thermal insulation material disclosed by the invention can be manufactured into wall thermal insulation mortar, thermal insulation blocks and thermal insulation boards, can be applied to different parts of a building, so as to ensure that the energy conservation index of the building meets the national mandatory standard, the fire rating can reach level A, and the drying shrinkage is low. A preparation process of the building exterior wall thermal insulation material is energy-saving, meanwhile, the recycling problem of industrial waste gypsum is solved, and the pollution of the industrial waste gypsum to the environment is avoided.

Description

technical field [0001] The invention relates to a thermal insulation material for building. Background technique [0002] First, after the public security department puts forward requirements on the fire protection grade of thermal insulation materials, building wall thermal insulation materials are mainly divided into three categories: ① thermal insulation mortar. There are mainly cement-based lightweight aggregate thermal insulation mortar and gypsum-based lightweight aggregate thermal insulation mortar; ② thermal insulation blocks. There are mainly concrete composite material insulation blocks filled with insulation materials in concrete hollow blocks and aerated concrete blocks, etc., which are used for non-load-bearing wall blocks of energy-saving building exterior walls; ③ insulation boards. There are mainly foamed cement insulation boards, composite material insulation boards, rock wool board insulation boards and other material insulation boards. ①③Types of insulat...
