Abstract

The invention discloses a preparation method of a modified inorganic penetrant polystyrene insulation board. The method comprises the following steps: 1, pretreating and foaming a polystyrene insulation board; 2, preparing inorganic penetrant slurry; 3, penetrating the pre-foamed polystyrene insulation board with the inorganic slurry; 4, airing or drying the polystyrene insulation board. By addingpart of calcium oxide to replace part of magnesium oxide, cost is saved and product stability is improved; by means of an added silicone water repellent, waterproof performance of the product can reach 100%, low-alkali glass fiber is taken as a grid structure, combined with vitrified glass beads and applied to the insulation board, thereby being capable of serving as a grid structure of the insulation board and an insulation fireproof layer, and the polystyrene insulation board has the characteristics of being anticorrosive, high in strength, waterproof, anti-radiation, insulating, light in weight, anticracking, stable in size, prolonged in service life and easy to construct. Compatibility between the inorganic penetrant slurry and polystyrene is improved by added acrylate, and penetranteffect is improved.

Description

technical field [0001] The invention relates to the technical field of energy-saving and thermal insulation of building exterior walls, in particular to a preparation method of a modified inorganic permeable polystyrene thermal insulation board. Background technique [0002] At present, the mainstream inorganic permeable thermal insulation boards use permeable materials that are expensive, and the penetration is not uniform enough, and the material stability is poor; the mainstream thermal insulation boards use metal as a grid structure, which is heavy and thermally conductive, and will break after a long time; A modified thermal insulation board molded, although good in fire resistance, has high thermal conductivity and heavy weight, making it difficult to construct. Contents of the invention [0003] The invention proposes a thermal insulation board with environmental protection and energy saving, uniform penetration, light weight, excellent fireproof and thermal insulat...
