Embodiment approach

[0019]

[0020] The weight of each composition of table 1 embodiment 1-4

[0021] Wherein, the expanded particles are expanded perlite.

[0022] The cotton fiber is asbestos or rock wool.

[0023] Described foaming agent is AC foaming agent.

[0024] According to the components of each embodiment in Table 1 and the weight of each component to make heat-insulating magnesium oxide board, the steps are: magnesium oxide, magnesium chloride, expanded particles, aluminum silicate fiber, cotton fiber, foaming agent, The reinforcing agent and water are added to the mixing equipment according to the above ratio, and after being uniformly stirred for 20 minutes, the base material is made; the base material is introduced into the mold, extruded after being extruded by the extrusion equipment, air-dried, and made into a heat-insulating Insulated magnesium oxide board.

Abstract

The invention discloses a heat insulation magnesium oxide board, which is formed by mixing the following raw materials in parts by weight: 70-100 parts of magnesium oxide, 50-75 parts of magnesium chloride, 35-50 parts of expanded granules, 20-30 parts of calcium silicate, 20-30 parts of aluminum silicate fiber, 10-20 parts of cotton fiber, 2-5 parts of foaming agent and 10-20 parts of water. In the heat insulation magnesium oxide board, the expanded perlite, calcium silicate and the aluminum silicate fiber all have excellent heat insulation performance; and with the foaming agent, combination among the expanded perlite, calcium silicate and the aluminum silicate fiber is facilitated, so that the heat insulation performance of the heat insulation magnesium oxide board is enhanced.

Description

technical field [0001] The invention relates to a magnesium oxide board, in particular to a heat-insulating and heat-insulating magnesium oxide board. The invention also relates to a manufacturing method of the heat-insulating and heat-insulating magnesium oxide board. Background technique [0002] In the field of construction, magnesium oxide board is a new type of multi-functional building material. Because it has the light flexibility and reprocessing performance of wood-like organic boards, and has the fire resistance and water resistance of inorganic boards, it is widely used in walls, ceilings and ceilings. , floor liners and other decorations with fire protection requirements. Traditional insulation boards are made of polystyrene foam boards, polyurethane foam boards, etc. These materials have general thermal insulation performance and poor thermal insulation performance, which cannot meet the needs of the modern construction industry.
