Method for preparing photocatalyst ecological bricks

Abstract

The invention relates to a building material preparation process, in particular to a preparation process for brick substrates such as pervious bricks or floor bricks or concrete building blocks and the like. A method for preparing photocatalyst ecological bricks comprises the following steps that: A, waste ceramic impurities are crushed into crushed ceramic materials after being cleaned; B, wastefilter materials with main ingredients of diatomite and expanded perlite are dried, and then, rough filter material regenerated materials and fine filter material regenerated materials are sieved; C,the crushed ceramic materials and the rough filter material regenerated materials which are obtained in the steps A and B are mixed with ordinary portland cement and water and are stirred into dry concrete according to certain mass parts, the dry concrete is made into brick substrates, then, the fine filter regenerated materials, sand or stone dust, mineral pigment, white cement, nanometer titanium dioxide powder and water are mixed and stirred to be made into plus materials of the brick substrates, and the plus materials and the brick substrates are simultaneously pressed and formed; and D, the photocatalyst ecological bricks obtained in the step C are cured until the design strength is reached.

Description

technical field [0001] The invention relates to a preparation process of building materials, in particular to a preparation process of permeable bricks or floor bricks or concrete blocks and similar brick substrates. Background technique [0002] Question 1: Ceramics are consumables widely used in the field of production and life. In recent years, the pollution of waste ceramics produced in the production of building ceramics to the environment has become increasingly serious. According to statistics, since 1997, waste ceramics has been increasing at a rate of 12%-20% every year. For example, take Jinjiang City as an example. It is a major ceramic production area. In 2008, the local average daily output reached more than 200 tons. Waste ceramics cannot be effectively used and dumped everywhere, which has seriously damaged the appearance of the local town and hindered local construction. .

Problems solved by technology

[0002] Question 1: Ceramics are consumables widely used in the field of production and life

For example, take Jinjiang City as an example. It is a major ceramic production area. In 2008, the local average daily output reached more than 200 tons. Waste ceramics cannot be effectively used and dumped everywhere, which has seriously damaged the appearance of the local town and hindered local construction.

[0003] Question 2: The filter material mainly composed of diatomite (a large amount) and expanded perlite (a small amount) is widely used in the filtration process of food production and processing enterprises, and it is also a large amount of consumables

Waste filter materials in food factories also have environmental pollution problems

[0004] Question 3: Although some brick substrates such as permeable bricks or some colored floor tiles or microporous concrete blocks have the functions of water permeability and moisturizing through the dense microporous structure in the brick substrate, their water absorption and moisturizing effects to be further improved

[0005] Problem 4: Since the urban ground is covered by a large amount of concrete pavement or brick pavement, it is impossible to plant a large number of green plants

Therefore, the city's air pollution index is high, and the city's self-purification ability is poor.
