Problems solved by technology

But existing polystyrene board thermal insulation system and polyurethane thermal insulation system are used in building maintenance structure to have following defect: one, no matter be polystyrene board and polyurethane, its synthetic raw material all is to extract from petroleum as main energy source
The preparation of them needs to consume a large amount of limited and non-renewable energy resources-petroleum; second, the main material of the building maintenance structure is an inorganic silicate system, while the main material of the insulation system represented by polystyrene board and polyurethane

Example

[0019] Examples 1-34

[0020] The embodiments of the present invention all consist of the following steps:

[0021] a. Weigh the fibers, toughening materials and surfactants listed in the table below and dissolve them in water to form a polymer emulsion;

[0022] b. Separately weigh the inorganic cementing materials, lightweight aggregates and fibers listed in the following table, put them in a mixer and mix them evenly to obtain a dry powder mixture;

[0023] c. Add the dry powder mixture of step b to the polymer emulsion of step a, stir and disperse to obtain a slurry;

[0024] d. Add the air-entraining agent listed in the following table to the slurry of step c, stir and disperse evenly, pour it into the film cavity, dry it completely, and then cut it.

[0025] The thermal conductivity test results of the plates prepared by each implementation are shown in the last column of the table. The test result shows that the heat preservation effect of the board of the invention is good...

Abstract

This invention discloses a method for preparing heat-insulating and sound-absorbing board material, which comprises: inorganic gelation material 10-95 parts, lightweight aggregate 5-90 parts, fibers 0.1-10 parts, air entraining agent 1-20 parts, surfactant 0.1-10 parts, toughening material 0.1-10 parts, and water 60-300 parts. The toughening material is one or more of latex nanopowder, poly (vinyl alcohol) and poly (acrylic acid). The board material has such advantages as good heat insulation, good sound absorbency, long service life, no pollution, and saved resources.

Description

technical field [0001] The invention relates to a thermal insulation and sound absorption board, in particular to an ecological thermal insulation and sound absorption board and a preparation method thereof. Background technique [0002] In order to achieve building energy saving and consumption reduction, the strategy currently adopted in my country is mainly to treat the building maintenance structure to reduce the heat transfer coefficient of the wall and roof. The specific way is to increase the laying of thermal insulation materials in the building maintenance structure. The existing technology mainly uses polystyrene board insulation system and polyurethane insulation system made of polystyrene pellets or polyurethane pellets as the main material, and their thermal conductivity can reach 0.045W / m respectively 2 .K and 0.026W / m 2 .K. It has a low thermal conductivity and can improve the thermal insulation effect when used in building maintenance structures. But exist...
