Abstract

The invention discloses a temperature-selfadjusting phase transition composite high temperature wall body manufacturing method, comprising: coating the wall body with temperature selfadjusting phase transition mortar, coating heat preservation putty and then coating elastic putty, and finally coating heat insulating paint, where the said temperature selfadjusting phase transition mortar is composed in weight percent of: temperature selfadjusting phase transition material 10-40%, hollow fiber material 5-35%, dispersible glue powder 8-38%, cement 12-42%, and lightweight aggregate 35-65%. And the invention provides a temperature-selfadjusting phase transition composite heat preservation wall body manufacturing method and the product. And the product has features of better heat preservation effect, high antifire performance, low wall body foundation requirements, high fastness of heat preservation layer, good decorative effect, no pollution, long service life, able to make large-area spreading and application, etc.

Description

Technical field [0001] The invention relates to a thermal insulation wall in the construction field, in particular to a manufacturing method of a self-temperature-regulating phase-change thermal insulation wall and a product thereof. Background technique [0002] To save energy, it is necessary to maintain the indoor temperature, and the insulation of the wall is very important to save energy, especially in the north. At present, a thermal insulation wall is realized by bonding expanded polystyrene foam board or high-density polystyrene extruded board on the outside of the wall, then thinly smearing cotton mortar on the outside of the wall, and coating the exterior wall paint. Although the external wall of this structure has a good thermal insulation effect, because the thermal insulation materials used are mainly expanded polystyrene foam board or high-density polystyrene extruded board, it has poor fire resistance and is not conducive to the foundation of the wall. Many d...

AI Technical Summary

Problems solved by technology

Although the external wall of this structure has a good thermal insulation effect, since the thermal insulation materials used mainly include expanded polystyrene foam board or high-density polystyrene extruded board, the fire performance is very poor, and the wall foundation Due to many defects such as high requirements, low insulation layer firmness and short service life, in engineering applications, there are often phenomena such as weak adhesion and large-area cracking, hollowing, falling off and / or cracks in the plastering mortar.

Generally, after three years, there will be serious water seepage problems, resulting in mildew and hair growth on the walls of the house, which is difficult to deal with

[0003] Another kind of thermal insulation wall is to coat polystyrene particle thermal insulation mortar on the outside of the wall. This kind of polystyrene particle thermal insulation mortar has a high thermal conductivity, and the effect of indoor thermal insulation is poor, which is far from meeting the requirement of 65% energy saving.

[0004] The third type of thermal insulation wall is to cover the outer layer of the polyurethane foam layer outside the wall. The polyurethane foam layer has a good thermal insulation effect and high firmness, which can better solve the problems of the two types of walls mentioned above. However, since the polyurethane foam layer can only be produced by combining two components, it has the disadvantages of high construction cost and poor decorative effect, especially serious environmental pollution. In today's era where people's awareness of environmental protection is increasing , it is difficult to promote the use of large-scale
