preparation example Construction

[0030] The preparation method of the environmental protection brick comprises the following steps:

[0031] S1: Preparation of hollow bricks

[0032] Mix cement, shale ore, fly ash, tailings sand, and kaolin, and stir evenly at a speed of 200-400r / min to make hollow bricks;

[0033] S2: Preparation of new foam materials

[0034] S21: Stir cement, glyoxal and water evenly at a speed of 100-300r / min to prepare a slurry;

[0035] S22: Calcium silicate, calcium sulfate, bentonite, magnesium borate, corn stalk powder, AR glass fiber, carbon fiber, water reducer, foaming agent, foam regulator, catalyst, crosslinking agent and foam stabilizer Stir for 2-3 hours at a rotational speed of 60-100r / min to obtain a foam solution;

[0036] 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 prepare a new foam material;

[0037] S3: Preparation of insulation bricks

Abstract

The invention discloses a novel foaming material which is prepared from, by weight, 25-45 parts of cement, 2-4 parts of calcium metasilicate, 2-3 parts of calcium sulfate, 2-3 parts of bentonite, 1-2 parts of magnesium borate, 1.5-2 parts of corn straw powder, 0.6-1.2 parts of AR glass fiber, 0.4-0.6 part of carbon fiber, 1.5-2.5 parts of water reducing agent, 0.2-0.8 part of foaming agent, 0.2-0.6 part of foaming adjusting agent, 0.1-0.3 part of catalyst, 0.3-0.6 part of cross-linking agent, 0.1-0.5 part of foam stabilizer, 20-30 parts of glyoxal and 240-300 parts of water. Concrete environment-friendly bricks prepared from the environment-friendly cement foaming material has the advantages of being good in heat insulation property and sound isolation effect, low in weight, resistant to press and the like.

Description

technical field [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a novel foaming material. 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 foaming materials currently on the market have disadvantages such as poor impact resistance an...
