Problems solved by technology

[0004] At present, there have been some relevant reports on the application of PET materials in the preparation of floors. Chinese patent CN110029796A discloses a floor in an environmentally friendly, wear-resistant and scratch-resistant PET floor. The surface layer and the balance bottom layer use non-PET materials, such as melamine, Phenolic resin, such substances will affect the recycling of PET flooring; Chinese patent CN109944411A, a PET plastic flooring and its molding method, discloses that in order to achieve the purpose of flame retardancy, the printing layer is also attached with impregnated carbon dioxide for flame retardancy. Aluminum impregnated paper layer; both have certain defects

Abstract

According to the PET flame-retardant floor and the preparation method thereof, a non-halogen material floor is prepared from a PET material, and a base material layer, a printing layer and a surface layer are all made of the PET material, so that recycling of the PET material is facilitated; the PET material does not generate harmful substances during combustion, and particularly, a modified inorganic flame retardant is additionally added into the PET color film, so that the flame retardant property of the PET material is further improved; the base material layer of the product is a uniformly foamed PET plate, so that the PET floor is lighter in weight, better in foot feeling and more prominent in sound insulation effect, and meanwhile, certain elasticity can be provided for the base material layer; in the preparation process, the color film and the transparent sheet are directly laminated through waste heat, so that the production energy consumption is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of preparation of a flame-retardant floor, in particular to a PET flame-retardant floor and a preparation method thereof. Background technique [0002] The most widely used plastic floor in the market is PVC floor, which has many advantages, the biggest feature is flame retardancy, so it is widely used in fire protection applications. But polyvinyl chloride releases hydrogen chloride and other toxic gases such as dioxins during combustion. [0003] PET material is commonly known as polyester resin, which is a condensation polymer of terephthalic acid and ethylene glycol, and together with PBT is collectively referred to as thermoplastic polyester, or saturated polyester. With excellent high and low temperature resistance, it can be used in the temperature range of 120 °C for a long time, short-term use can withstand high temperature of 150 °C, and can withstand low temperature of -70 °C. [0004] At present, there h...
