Imitated natural stone vitrified tile using industrial waste as raw material and preparation method of imitated natural stone vitrified tile

Abstract

The invention discloses a natural stone imitating vitrified tile using industrial wastes as raw materials. The natural stone imitating vitrified tile comprises the following raw materials: 40-55 wt% of waste porcelain powder with a particle size of 0.5-2 mm, 12-18 wt% of transparent frit, 6-10 wt% of cement waste with a particle size of 0.1-0.5 mm, 10-15 wt% of waste red brick powder with a particle size of 0.1-0.5 mm, and 14-22 wt% of a reinforced blank. In addition, the invention further discloses a preparation method of the natural stone imitating vitrified tile using the industrial waste as the raw material. According to the invention, industrial wastes such as waste porcelain powder, waste red brick powder, cement waste and the like are comprehensively recycled, large-particle waste porcelain with different colors and specifications is used as color spots of the imitated natural stone, and the imitated natural stone vitrified brick is formed through the surface adhesion effect of the transparent frit, so that the utilization rate of industrial solid wastes is increased, the application field of the industrial solid wastes is expanded, and the application prospect is wide. And moreover, the production cost of the vitrified brick is reduced, the additional value of the product is improved, and the requirements of industry and social green economic development can be better met.

Description

technical field [0001] The invention relates to the technical field of building ceramic materials, in particular to a vitrified brick using industrial waste as a raw material and a preparation method thereof. Background technique [0002] The amount of industrial waste is huge, its composition is complex, and it is difficult to deal with. The existing disposal methods such as landfill and accumulation not only occupy a large amount of land, but also affect the growth of organisms and human health. Properly treating industrial waste as a resource-based raw material and processing it into products is one of the green roads for sustainable development of industrial solid waste. [0003] Vitrified brick is a kind of full-body brick with smooth surface, high strength, good decorative effect and wide application. It is called "the king of floor tiles". Vitrified tiles are increasingly becoming the focus of the industry. The technical difficulties of using industrial waste to pre...

AI Technical Summary

Problems solved by technology

The technical difficulties of using industrial waste to prepare imitation natural stone vitrified bricks mainly lie in: (1) The raw materials of industrial waste are different, and only waste porcelain includes high-temperature waste porcelain (1280-1320°C) and medium-temperature waste porcelain (1200°C) ~1250℃), low-temperature waste porcelain (1130~1180℃), which brings great inconvenience to the recycling of solid waste

(2) It is difficult to process industrial waste raw materials. Some solid waste materials are hard, low water absorption and low shrinkage, but the crushing cost is high; some solid waste materials are loose and porous, have certain water retention, but the sintering temperature is high

(3) The amount of industrial solid waste added to vitrified bricks is affected by the particle size of solid waste materials and the bonding wettability at high temperature. The bonding wettability of large particles of solid waste materials at high temperatures and other materials is poor, which is difficult to meet The water absorption rate of vitrified bricks is lower than 0.5%. If the addition of sintering aids is increased and the water absorption rate is reduced, the defects of brick body deformation and shrinkage will be increased.

The finer grinding of raw material particles will increase the production cost, and some color characteristics of the large particles of solid waste materials will also disappear, so it is necessary to add coloring pigments for color development
