Method for preparing water permeable brick with vitrified tile waste and product obtained

Abstract

The invention relates to a method for preparing a water permeable brick with vitrified tile waste and a product obtained. The method comprises the followings steps: taking industrial waste (the vitrified tile waste) as an aggregate; adding a small amount of following mineral raw materials and chemical raw materials in weight percentages: 73-78% of the vitrified tile waste, 3-4% of clay, 9-13% of feldspar, 10% of water glass, 0-5% of calcium carbonate and 0-5% of aluminum hydroxide; blending, mixing, forming at the forming pressure of 20MPa, drying in the air for 1-2 days, firing at the firing temperature of 800-1100 DEG C for 2 hours and keeping for 0.5h heat preservation to obtain the product. The water permeable brick has the advantages of simple preparation process, easy control, low firing temperature, low production cost and excellent product performance, and can be widely applied to ground laying of public places such as walkways, parking areas, squares and the like which require rain penetration.

Description

technical field [0001] The invention belongs to the field of inorganic materials, and in particular relates to a production method of permeable bricks. The products prepared by the method are suitable for laying on the ground of public places such as sidewalks, parking lots and squares that must permeate rainwater. Background technique [0002] With the development of society, the ground surface of modern cities is gradually covered by water-blocking materials such as buildings and concrete, and the hardened ground is increasing year by year. The traditional ground decoration materials are mainly stone, cement and ceramic square tiles, etc. A common feature of these materials is that they are impermeable, which has caused a lot of trouble, such as in the rainy season, it will cause inconvenience to pedestrians and traffic. In order to solve the above problems, various permeable bricks have emerged as the times require. Chinese patent (publication number CN1336349) discloses...

AI Technical Summary

Problems solved by technology

Because there are many types of wall and floor tiles (including porcelain, pottery, and stoneware), the permeable bricks produced by this method have certain shortcomings, that is, the preparation process is not easy to control due to the different raw materials used in actual production. The performance of the product changes greatly; at the same time, wood chips are used as a pore-forming agent in the production process, which makes the production process more complicated, the hollowing effect is not obvious, and the firing temperature is relatively high (1300 ° C), so the production cost is high
