Abstract

The invention provides a waste textile wall thermal insulation plate and a preparation method of the waste textile wall thermal insulation plate, and relates to the technical field of thermal insulation materials. The waste textile wall thermal insulation plate comprises the following components by mass: 30-35% of waste textiles, 10-15% of waste plastic, 7-10% of thermoplastic polyurethane, 10-15%of a flame retardant, 10-15% of polyether polyol, and 20-25% of polymeric MDI (diphenylmethane diisocyanate). The provided technique for the thermal insulation plate solves the technical problems that the waste textile is difficult to process and the recovery rate is low. Due to the matching of the waste textile and the waste plastic, the strength and the hardness of a product are improved whilethe production cost is lowered. The wall thermal insulation plate is excellent in thermal insulation property, strength and flame retardant property, and the production cost is low. The idea of turning waste into wealth and being green and environmentally friendly is truly realized, and the comprehensive recovery rate of the resource is increased.

Description

technical field

[0001] The invention relates to the technical field of thermal insulation materials, in particular to a waste textile wall thermal insulation board and a preparation method thereof. Background technique

[0002] In recent years, with the rapid development of our country's economy and the continuous improvement of the degree of industrialization, people's income level is increasing day by day, and the pursuit of personalization and fashion has promoted the upsurge of people buying clothes. Excessive consumption will bring a lot of waste textiles. The total output of waste textiles in my country has exceeded 20 million tons, of which about 70% are synthetic fibers, most of which are non-renewable fibers with poor biodegradability and serious environmental pollution. The comprehensive utilization rate is less than 10%, and most areas still use the incineration and landfill method to deal with these waste textiles, which means that it has caused serious pollution ...
