preparation example Construction

[0030] The preparation method of the novel concrete environmental protection brick includes the following steps:

[0031] S1: Preparation of hollow brick

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

[0033] S2: Preparation of cement foam material

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

[0035] S22: Combine calcium carbonate, calcium silicate, limestone, magnesium borate, wheat straw powder, AR glass fiber, carboxymethyl cellulose, water reducing agent, foaming agent, foaming regulator, catalyst, crosslinking agent and foam stabilizer The agent is stirred at a speed of 60-100r / min for 2-3h to obtain a foam liquid;

[0036] S23: adding the foam liquid prepared in step S22 to the slurry prepared in step S21, and stirring uniformly at a rotation speed of 150-200 r / min to prepare a new cement foam material;

[0037] S3: Preparation of insulation brick...

Abstract

The invention discloses a novel cement foam material. The novel cement foam material is prepared from, by weight, 23-42 parts of cement, 2-3 parts of calcium carbonate, 2-3 parts of calcium silicate, 2-3 parts of limestone, 1-2 parts of magnesium borate, 1-2 parts of wheat straw powder, 0.6-1 part of AR glass fibers, 0.4-0.8 part of carboxymethylcellulose, 1.5-2.5 parts of a water reducing agent, 0.2-0.8 part of a foaming agent, 0.2-0.6 part of a foaming regulator, 0.1-0.3 part of a catalyst, 0.3-0.6 part of a crosslinking agent, 0.1-0.5 part of a foam stabilizer, 20-30 parts of glyoxal and 240-300 parts of water. An environment-friendly concrete brick made of the novel cement foam material has the advantages of being good in heat preservation and heat insulation performance and sound insulation effect, light, resistant to pressure and the like.

Description

Technical field [0001] The invention belongs to the technical field of building material preparation, and specifically relates to a new type of cement foam material. Background technique [0002] With the promotion of building energy saving and people's increasing demand for the comfort of living environment, thermal insulation materials have received more and more attention from people. The existing thermal insulation composite bricks or blocks mainly have various forms such as inlaid thermal insulation materials, thermal insulation interlayers or thermal insulation holes and trenches. As one of the house thermal insulation materials, the room temperature non-fired foam bricks are more and more popular because of their thermal insulation, sound insulation, fire resistance, and strength superior to traditional thermal insulation materials. However, the existing foam materials on the market have disadvantages such as poor impact resistance and relatively poor durability. Summary...
