CN103043964A - Method for preparing clay baking-free brick - Google Patents

Abstract

The invention discloses a method for preparing a clay baking-free brick, belonging to construction material. The preparation method comprises the following steps: uniformly mixing 8% by weight of clay, 79% by weight of stone flour, 8% by weight of coagulation material, and 5% by weight of water, compacting and forming under high pressure, stewing with the temperature no less than 5 DEG C for 10-28 days. The method of the invention has the advantages of small floor space, baking-free manner, environmental protection preparation process. The method thoroughly eliminates the combustion harm to the environment and the human body, and reduces the production cost of the enterprises.

Description

The preparation method that a kind of clay is non-burning brick

Technical field

The invention belongs to material of construction, relate to brick, be specifically related to the non-burning brick preparation method of a kind of clay.

Background technology

Brick is artificial small-sized bulk for building, minute vitrified brick (mainly referring to clay brick) and no-firing brick (Dinas brickes, flyash brick etc.).Clay brick forms through pug processing, moulding, drying and roasting take clay as main raw material, and clay brick is gathered materials on the spot, and low price is durable in use, also has the advantages such as fire prevention, heat insulation, sound insulation, the moisture absorption, uses extensively in civil construction project.Flyash brick mixes the consolidating materials such as colliery powder or clay take flyash as main raw material, forms through batching, moulding, drying and roasting.

High speed development along with Building Trade in China, the demand of clay brick strengthens year by year, but existing clay brick will take very large land area when making, and then builds large-scale brickkiln and come heat-agglomerating, so not only increase production cost, and can cause serious pollution to environment.

In order to reduce the production cost of enterprise, dwindle usable floor area, reduce and pollute, be necessary to research and develop the novel preparation technology of a cover.

Summary of the invention

The purpose of this invention is to provide the non-burning brick preparation method of a kind of clay.

The present invention is achieved by the following technical solutions:

The preparation method that a kind of clay is non-burning brick may further comprise the steps:

At first be to be respectively 8% clay, 79% stone flour, 8% coagulated material with mass ratio, 5% water stirs, then then under high pressure compression moulding deposited under 〉=5 ℃ temperature condition 10-28 days, avoids direct sunlight between staging life, the watering moisturizing, and get final product.

Further, described coagulated material is silicate cement.

Described high pressure is 25MPa.

Will be non-burning brick through measuring according to the clay that the inventive method makes, it is withstand voltage, folding, waterproof, acid-proof alkaline all are better than existing clay brick.

The present invention is take clay as main raw material, add simultaneously a certain amount of stone flour, it is the discarded pin material of building stones Building Materials Factory, with low cost, when making, required land area is little, get product without sintering, the making processes environmental protection has thoroughly been eliminated the harm that burning causes environment and human body, and has been reduced the manufacturing cost of enterprise.
