Problems solved by technology

[0002] Building exterior wall insulation is a technology that benefits the country and the people vigorously advocated by the country. It can save energy and reduce consumption, and reduce energy waste; the existing technology of exterior wall insulation mainly includes spraying insulation materials on exterior walls and pasting insulation boards on exterior walls. etc., the insulation materials used are not the same, but these technologies either have the problem of not obvious insulation effect, or the problem of unreliable pasting, or increase the thickness of the outer wall, resulting in a bloated and unsightly appearance of the building.

Embodiment 1

[0031] Such as figure 1 As shown, a polyurethane external wall thermal insulation brick includes a brick body 1, characterized in that: the brick body 1 is provided with a core material cavity, and the core material cavity is filled with polyurethane 2;

[0032] The external dimensions of the thermal insulation brick refer to the current specifications of external wall tiles or veneer bricks;

[0033] The thickness of the core material (polyurethane) can be determined according to the requirements of different regions or users with reference to "Technical Guidelines for External Thermal Insulation Engineering of Polyurethane Hard Foam External Walls".

[0034] The brick body 1 is made by solidification of cement mortar. Generally, 1 part of cement and 3 parts of sand are used to make cement mortar, and 1 part of white cement and 3 parts of white quartz sand can also be used to make cement mortar.

[0035] In order to increase the appearance, a decorative layer 3 is provided on th...

Embodiment 2

[0058] Based on the above structure, the difference from the first embodiment is that a polyurethane filling port is provided on the brick body, and the polyurethane filling port communicates with the core material cavity.

[0059] The brick body design of this structure is mainly for the convenience of production. Usually, the current production line for producing exterior wall tiles or exterior walls can be used to produce the above-mentioned thermal insulation tiles with a little technical modification. When forming, add a layer of plastic plate coated with a release agent in the middle of the embryo. The original size of the plastic plate is determined according to the design. After drying and forming, the plastic plate is drawn out and fired into a hollow tile or tile. Then, Then insert the polyurethane rigid foam board to obtain the finished product.

Abstract

The invention provides a method for making polyurethane exterior wall insulation bricks, comprising the following steps: preparing a polyurethane material board; preparing cement mortar; immersing the polyurethane material board in the mixed cement mortar, coating it evenly, removing it, coagulating it, and then Immerse in cement mortar, and then coat evenly, take out, condense, and repeat this many times until the brick body is made; trim the outer surface of the above brick body; construct the finishing layer; condense, and the finished product is obtained. The insulation brick has a simple production method and is easy to process and produce. It utilizes the excellent insulation performance of polyurethane to greatly improve the insulation effect of buildings using this brick. At the same time, the brick structure produced by this method is exquisite in design and reliable in quality. Use decorative bricks or anti-corrosion bricks.

Description

Technical field [0001] The invention relates to a manufacturing method of thermal insulation bricks for buildings, in particular to a manufacturing method of polyurethane external wall thermal insulation bricks, and belongs to the field of building materials. Background technique [0002] Building exterior wall insulation is a technology that is strongly advocated by the country to benefit the country and the people. It can save energy and reduce consumption and reduce energy waste. The existing technology of exterior wall insulation technology mainly includes exterior wall spray insulation materials and exterior wall paste insulation boards. Etc., the thermal insulation materials used are not the same, but these technologies either have the problem of insignificant thermal insulation effect, or the problem of insecure bonding, or increase the thickness of the outer wall, resulting in a bloated and unsightly building appearance. [0003] In order to solve the above problems, peop...
