Embodiment 1

[0036] The stone processing waste in this embodiment is waste and leftover materials in the processing process, specifically selected from sandstone and shale stone processing waste; the organic fiber is waste textile fiber, selected from waste polyester textile.

[0037] An artificial marble prepared from waste polyester textiles and a preparation method thereof, the preparation process is as follows:

[0038] A. Add sandstone and shale processing waste with a particle size of 3-5mm into a disc-shaped mechanochemical reactor for grinding, while controlling the temperature of the circulating cooling water at 20-25°C and the speed of 150rpm. Repeat grinding 50 times to obtain 80 -100 mesh fine stone powder; put waste polyester textiles with a length of 30-45mm into the disc-shaped mechanochemical reactor, control the temperature of the circulating water at 25-30°C, and the speed of 100rpm, repeat grinding 10 times to obtain thin organic fiber;

[0039] B. Weigh 50 parts of sto...

Embodiment 2

[0045] The stone processing wastes in this embodiment are wastes and scraps during processing, specifically selected from granite stone processing wastes; the organic fibers are waste blended mainly polyester or waste polyester textiles.

[0046] A kind of preparation method step of the artificial marble prepared with waste polyester textile is as follows:

[0047] A. Put the granite stone processing waste with a particle size of 1-5mm into a disc-shaped mechanochemical reactor for grinding, and control the temperature of the circulating cooling water at 15-20°C and the speed of 120rpm.

Abstract

The invention discloses an artificial marble prepared from waste polyester fabrics and a preparation method thereof. The artificial marble is prepared from following components in parts by weight: 38to 45 parts of unsaturated polyester resin, 50 to 58 parts of aggregate mainly composed of waste materials generated in stone processing, 19 to 25 parts of a reinforcing agent namely organic fibers oftextiles, 1 to 2 parts of a curing agent, 1 to 2 parts of a promoter, 1 to 2 parts of a coupling agent, and 0.1 to 0.2 part of a light stabilizer. The waste polyester textiles are utilized efficiently; a light stabilizer is added, the weatherability and anti-aging property of the artificial marble are enhanced; a sandwich design is adopted at the same time, the manufacturing cost is reduced, andthe artificial marble meets the standards of the building material industry.

Description

technical field [0001] The invention belongs to the technical field of building materials, and also belongs to the field of high-quality resource utilization, and specifically relates to an artificial marble prepared from waste polyester textiles and a preparation method thereof. Background technique [0002] With the rapid development of my country's economy and society, the consumption level of residents continues to increase, and the demand for polyester continues to rise. The main component of polyester textiles is polyester fiber PET. PET molecules are widely used because of their high melting point, tensile strength, stiffness and hardness. The subsequent recycling of waste polyester textiles is facing huge challenges. challenge. [0003] At present, polyester recycling methods mainly include physical recycling and chemical recycling. Traditional physical recycling methods such as extrusion, shearing, granulation, etc., greatly reduce the performance of the material, ...
