Embodiment 1

[0028] A kind of technology that utilizes polishing waste slag to prepare breath brick, its step comprises:

[0029] a), preparation of bottom material: according to the percentage of mass, respectively take polishing waste slag 30%, albite powder 12%, calcined talc 6%, ball clay 16%, lithium limestone powder 11%, wollastonite powder 20%, quartz 5% %, fast ball milling for 20 minutes, drying and granulation, passing through a 20-mesh sieve, and finally aging to obtain a base material with a water content of 9% for later use;

[0030] b), preparation of the fabric: according to the percentage of mass, respectively take 40% of polishing waste residue, 40% of diatomite, 10% of ball clay, 5% of wollastonite powder, and 5% of lithium limestone powder. Put the diatomite into the mixture for 1 minute (the time of diatomite ball milling should not be too long, or it will destroy its structure), then dry and granulate, pass through a 20-mesh sieve, and finally get a fabric with a moist...

Embodiment 2

[0037] A kind of technology that utilizes polishing waste slag to prepare breath brick, its step comprises:

[0038] a), preparation of bottom material: according to the percentage of mass, respectively take polishing waste slag 30%, albite powder 10%, calcined talc 5%, ball clay 18%, lithium limestone powder 20%, wollastonite powder 16%, quartz 1 %, fast ball milling for 13 minutes, drying and granulation, passing through a 20-mesh sieve, and finally aging to obtain a bottom material with a water content of 8.5% for subsequent use;

[0039] b), the preparation of the fabric: according to the percentage of mass, respectively take 40% of polishing waste residue, 35% of diatomite, 14% of ball clay, 6% of wollastonite powder, and 5% of lithium limestone powder. Put the diatomite into the mixture for 1 minute (the time of diatomite ball milling should not be too long, otherwise it will destroy its structure), then dry and granulate, pass through a 20-mesh sieve, and finally get a ...

Embodiment 3

[0046] A kind of technology that utilizes polishing waste slag to prepare breath brick, its step comprises:

[0047] a), the preparation of bottom material: according to the percentage of mass, respectively get polishing waste slag 30%, albite powder 15%, calcined talc 5%, ball clay 20%, lithium limestone powder 10%, wollastonite powder 20%, quartz 0% %, fast ball milling for 14 minutes, drying and granulation, passing through a 20-mesh sieve, and finally aging to obtain a base material with a water content of 10% for subsequent use;

Abstract

The invention discloses a process for preparing a ventilating brick by using polishing waste residue. The process comprises the steps of preparing a backing material, preparing a plus material, distributing, pressing and forming, drying, and finally firing to prepare the ventilating brick. The ventilating brick is formed by using kieselguhr and the polishing waste residue as main raw materials through scientific proportioning and high-temperature firing. Due to the existence of the porous kieselguhr, a large quantity of micro pores exist in a brick body, and are capable of effectively adjusting air humidity, purifying indoor harmful gases and eliminating peculiar smell; due to the introduction of the polishing waste residue, the sintering temperature is reduced, thus the strength of the brick is enhanced; the prepared ventilating brick has extremely strong physical adsorption performance and ion exchange performance as well as acoustic absorption and thermal insulation, and also has functions of dehumidifying, deodorizing and purifying indoor air. Meanwhile, the process disclosed by the invention is simple, is high in production efficiency, and is reduced in cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a process for preparing breathing bricks by using polishing waste residue. Background technique [0002] With the development of industry and the gradual improvement of people's living standards, people pay more and more attention to the environmental protection of buildings and building materials. In recent years, a new type of interior decoration material products has been produced from diatomite with a microporous structure in foreign countries. Because diatomite itself is an excellent environmental protection material, this type of material product does not contain harmful chemicals. In addition to the characteristics of non-combustibility, sound insulation, waterproof, light weight and heat insulation, it also has the functions of dehumidification, deodorization, and indoor air purification. [0003] Polishing waste is mainly produced during the grinding and poli...
