Problems solved by technology

[0004] At present, there are materials such as EVA or PETG for halogen-free flooring on the market, but these materials have obvious disadvantages. EVA material is not easy to process, the product has poor wear resistance, and the product has poor dimensional stability; PETG material is hard and brittle, and it is not easy to be rolled. Processing, and the product flexibility is extremely poor, and the foot feel is extremely poor as a floor; at present, a small number of peers have studied the use of PP material to produce floors. Since PP is a non-polar material, the surface energy is low; PP is a crystalline high polymer with high hardness. , not easy to process; PP is a halogen-free and non-flame-retardant material, so there are the following problems:
[0005] 1) Since PP is a non-polar material with low surface energy, the printing ink on the surface of PP color film is easy to fall off; the surface of PP transparent material has poor UV adhesion, cracking and falling off.
[0006] 2) Due to the high hardness of PP resin, it is difficult to plasticize, so it cannot be produced by calendering process
[0007] 3) PP is a halogen-free material, which cannot achieve the flame-retardant effect of PVC halogen-free materials
[0008] 4) Since the PP material is hard and brittle, the floor elasticity is not as good as the PVC floor
[0009] 5) Due to the large difference in different PP materials and the large difference in processing temperature, the PP transparent material, the PP color film and the PP base material are not well bonded, and the delamination phenomenon is serious

Description

technical field [0001] The invention belongs to the field of floors, and in particular relates to a halogen-free environment-friendly wear-resistant elastic floor and a preparation method thereof. Background technique [0002] At present, PVC flooring is mainly made of polyvinyl chloride and its copolymer resin as the main raw material, adding fillers, plasticizers, stabilizers, colorants and other auxiliary materials, on the sheet continuous substrate, through coating process or calendering, extrusion or extrusion process; halogen-containing compounds are widely used in production and life. However, due to the serious negative effects of various organic halogen compounds on the environment and human body, from Freon to POPs, from PVC to brominated flame retardants (BFR), the harm of organic halogen compounds to human body and natural environment is indisputable fact. The "halogenation-free" process has already started in developed countries, and many corresponding laws an...
