Description

Sintered permeable brick which is not easy to block and preparation method thereof

Technical field

The invention relates to the technical field of permeable bricks, in particular to a sintered water permeable brick which is not easy to be blocked and a preparation method thereof.

Background technique

The permeable brick is a new century-old environmental protection building material that was born to alleviate the urban shackles while maintaining moisture and maintaining the ecological balance of the city. It uses solid waste materials such as waste ceramic tiles (waste polished tiles, waste polished glazed tiles, waste tiles, etc.), stone scraps, slag, etc. as the main raw materials, with molding aids, adding appropriate amount of binder, and forming twice by fabric. , high temperature firing, is a green product.

Permeable bricks can consume a large amount of waste ceramic tiles (solid waste such as stone scrap or slag), which not only solves the problem of solid waste disposal at present, but also greatly reduces environmental pollution. The ceramic permeable bricks produced can be directly used in urban construction and turned into waste. Therefore, it has obvious social significance.

The permeable bricks are divided into sintered permeable bricks and concrete permeable bricks, wherein the sintered permeable bricks need to be fired at a high temperature, and the concrete permeable bricks do not need to be fired at a high temperature.

Prior Art 1 is an invention patent disclosed in CN 101955349 B, which discloses a water permeable brick which uses ceramic waste powder, waste glass powder, waste porcelain powder, municipal base waste powder, and oxidation. Calcium, calcium sulphate, bentonite, talc powder, waste ash powder, waste plant powder and water are used as raw materials, stirred in a wet state, and then mechanically vibrated and extruded into a permeable brick lower layer brick, and then used a secondary cloth machine in the permeable water The upper part of the brick under the brick is evenly covered with a layer of fine fabric (the main component is waste ceramic chip powder, bentonite, water), and then it is made into a ceramic waste slag sintered water-permeable green brick under the pressure of 25-30 MPa for natural drying. Then, the ceramic slag permeable and environmentally-friendly bricks which have been naturally dried are sent to a tunnel kiln for roasting, and the temperature is controlled to be fired in the range of 1150 to 1200 °C. In the above scheme, the municipal base waste sludge fine powder and bentonite are binders. In the prior art 1, the waste ceramic chip powder is added in an amount of 20-30 parts, the bentonite is added in an amount of 5-8 parts, and the municipal base waste mud powder is added in an amount of 20-30 parts, that is, waste. The ceramic chip powder is added in an amount of about 20 to 30 parts, and the binder is added in an amount of about 25 to 38 parts. The waste ceramic chip powder is added in a small amount, the binder is used in a large amount, and the ultimate load of the binder is low, resulting in low strength of the green body after molding.

The raw material of the permeable brick disclosed in prior art 2 is mainly waste polished brick, and the raw material is formulated as: 10-40 parts of waste ceramic tile and 66-130 parts of binder, wherein the binder comprises 60-90 parts of bentonite, frit (glass powder, etc.) 5-20 parts, sodium carboxymethyl cellulose 1-20 parts.
