Novel environmentally-friendly ceramic permeable brick and preparation method thereof

Abstract

The invention discloses a technology of a novel environmentally-friendly ceramic permeable brick. In the method, ceramic slag is taken as the raw material which is sintered at 800 DEG C and the method comprises the following steps: adding cement as the binder, and vibrating and pressurizing to prepare and mould the finished product. In the method, ceramic slag is used as the raw material, wherein the fragments and slag of the vitrified tile are sintered at 1100-1250 DEG C, the Moth's hardness is no less than 7 and is more than the hardness of granite; and the compressive strength of the permeable brick prepared from the raw material is more than 30MPa, the flexural strength is more than 3MPa and the water permeability is more than or equal to 3*10<-2>cm / s. Sand blasting treatment is performed on the surface of the product to ensure that the natural color of ceramic is outstanding, the color of the product can be more gorgeous and long-lasting, and the high water permeability and skid resistance can be maintained. By adopting the new environmentally-friendly ceramic permeable brick, environmental pollutions and resource wastes can be reduced, cyclic utilization can be realized and the product has high compressive strength, flexural strength and permeability effect, thus rain and snow water can fast penetrate the underground to supplement the groundwater, the urban heat island effect can be reduced, the municipal drainage load can be lowered, ecological balance can be maintained and the ground settlements and noises can be reduced. The product has rich color and good landscape effect.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a novel environment-friendly ceramic permeable brick. Background technique [0002] As the world's largest ceramic producer, China has a large amount of ceramic waste slag that is discarded as garbage every day. At present, there is no successful technology for producing environmentally friendly ceramic permeable bricks from ceramic waste in China. Among them, 1. The Chinese patent application number is ： 99104294.8， The name is the manufacturing method of permeable bricks, and the patent application date was September 18, 2002. It involves a kind of production of ceramic permeable bricks by using ceramic waste residue. The products of this process are sintered at 1150°C---1250°C. Energy consumption, high pollution, and no environmental protection concept value; coupled with the high-temperature sintering process of the product, the internal pores stick and shrink, and the wate...

AI Technical Summary

Problems solved by technology

The product produced by this method has the following deficiencies: 1. a large number of chemical products based on styrene-acrylic emulsion, pure acrylic emulsion, styrene-butadiene emulsion and epoxy resin are used as the bonding material additive, and the cost rises sharply more than 50%, and the chemical raw material contains Carcinogenic substances, the finished products produced are toxic, and rainwater penetrates into the ground through this product, causing artificial pollution

②The color of the finished product is extremely single, and has no cultural landscape value

③The product needs to be maintained for 28 days before it can be released from the mold. It cannot be mass-produced and has no actual production value.

3. Patent application number: 200810072064.7, the name is a new type of permeable brick, and the public date is May 13, 2009. The product produced by this method, ①The production process does not use vibration and pressure technology, so that the compressive strength of the finished product is only 10- 20MPa, did not meet the national industry standard ≥ 30MPa requirements, the product is unqualified

If you want to increase the strength of the product, you can only increase the amount of cement, which will make the water permeability of the product poor, and finally fail to meet the requirements of the national industry standard; Soil; ③Due to the use of pigment dyeing, the color of the product is very easy to fade and change when it is outdoors, which will affect the landscape effect
