Embodiment 1

[0028] This embodiment provides a non-fired ceramic permeable brick with unique water permeability and water permeability made of waste ceramics, including: ceramic granules with a polymer coating and an adhesive, and the polymer coating The ceramic granules are mixed and bonded by the adhesive and solidified; wherein, the particle diameter of the ceramic granules is 0.01-20mm, and the polymer coating is epoxy resin adhesive, acrylic resin adhesive and polyurethane adhesive. One or more; the adhesive is one or more of epoxy resin adhesives, acrylic resin adhesives and polyurethane adhesives. Use ceramic granules with a particle diameter of 0.01-20mm and polymers to make particles with a polymer coating, and then use an adhesive to bond the ceramic granules with a polymer coating to form a building material with good water permeability. , the building material can be applied to the production of building materials, realizing the recovery and utilization of ceramic granules. Th...

Embodiment 2

[0037]This embodiment provides a method for preparing a water-permeable functional brick, which includes mixing, molding and curing the ceramic granules according to the present invention and a polymer.

[0038] Specific steps include:

[0039] Step S1: crushing waste ceramics to obtain ceramic granules;

[0040] Step S2: performing particle size screening on the ceramic granules, and selecting ceramic granules with a particle diameter of 0.01-20 mm;

[0041] Step S3: performing polymer coating layer processing on the screened ceramic granules;

Abstract

The invention discloses a baking-free ceramic water permeable brick and a preparation method thereof. The baking-free ceramic water permeable brick comprises broken ceramic particles and an adhesive, wherein the broken ceramic particles are provided with polymer coating layers and are mixed and adhered by virtue of the adhesive and are cured; the particle diameters of the broken ceramic particles are 0.01mm-20mm, the polymer coating layers are one or more of epoxy resin, acrylic acid resin and polyurethane; and the adhesive is one or more of an epoxy resin adhesive, an acrylic acid resin adhesive and a polyurethane adhesive. Waste ceramic is broken into the broken ceramic particles with the particle diameters of 0.01mm-20mm so as to be prepared into particles with the polymer coating layers by virtue of polymers, and the broken ceramic particles with the polymer coating layers are mixed and adhered by virtue of the adhesive and are cured to form the ceramic water permeable brick with good water permeability, thereby realizing the recycling and utilization of the waste ceramic.

Description

technical field [0001] The invention relates to the technical field of environmental protection application of waste ceramics, more specifically, relates to an unfired ceramic permeable brick and a manufacturing method thereof. Background technique [0002] At present, the global freshwater resources are becoming increasingly scarce, and scientifically and rationally obtaining and utilizing water resources is becoming an increasingly important research topic. Rainwater is one of the important ways for human beings to obtain fresh water resources. However, the cities where human beings live are mainly paved with impermeable materials such as granite, marble, glazed bricks, cement and asphalt, such as city squares, commercial streets, sidewalks, community activities and Occupied by hardened ground such as parking lots. When it rains, the hardened ground completely prevents rainwater from infiltrating directly into the ground, resulting in water accumulation on the road, which...
