preparation example Construction

[0036] The preparation method of the novel insulating brick comprises the following steps:

[0037] S1: Preparation of hollow bricks

[0038] Mix cement, shale ore, ceramsite, lime, and pumice, and stir evenly at a speed of 200-400r / min to make hollow bricks;

[0039] S2: Preparation of cement foam material

[0040] S21: Stir cement, glyoxal and water evenly at a speed of 100-300r / min to prepare a slurry;

[0041] S22: Calcium carbonate, barium sulfate, bentonite, magnesium borate, rice straw powder, AR glass fiber, carboxymethyl cellulose, water reducer, foaming agent, foam regulator, catalyst, crosslinking agent and stabilizer The foaming agent is stirred for 2-3 hours at a speed of 60-100r / min to obtain a foam liquid;

[0042] S23: Add the foam liquid prepared in step S22 to the slurry prepared in step S21, and stir evenly at a rotating speed of 150-200r / min to obtain a cement foam material;

[0043] S3: Preparation of insulation bricks

[0044] Fill the cement foam ma...

Abstract

The invention discloses a new type of thermal insulation brick, which comprises a hollow brick as the outer shell of the brick body and cement foam material filled in the cavity of the brick body. The hollow brick includes the following raw materials: cement, shale ore, ceramsite, lime, pumice The cement foaming material includes the following raw materials: cement, calcium carbonate, barium sulfate, bentonite, magnesium borate, rice straw powder, AR glass fiber, carboxymethyl cellulose, water reducer, foaming agent, foam Foam regulator, catalyst, crosslinking agent, foam stabilizer, glyoxal, water. The novel thermal insulation brick of the present invention has the advantages of excellent thermal insulation, sound insulation effect, light weight and pressure resistance, etc.; the method for preparing the novel thermal insulation brick does not require autoclaving and maintenance, and the equipment investment is small, the process is simple, the operation is simple, and it is easy to popularize. And the quality of the products produced is stable.

Description

【Technical field】 [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a novel thermal insulation brick. 【Background technique】 [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. Existing thermal insulation composite bricks or blocks mainly include multiple forms such as inlaying thermal insulation materials, setting thermal insulation interlayers, thermal insulation holes, and trenches. As one of the thermal insulation materials for houses, non-fired foamed bricks at room temperature are more and more popular because of their thermal insulation, sound insulation, fire prevention, and strength superior to traditional thermal insulation materials. However, the foamed bricks in the existing market have disadvantages such as poor impact resist...
