Abstract

The invention relates to the field of recycling modification and processing technology of polymer materials, and relates to a modified plastic, and a preparation method and an application thereof. The modified plastic is prepared by the following components of, by weight, 100 parts of waste polyvinyl chloride (PVC) plastics, 25-40 parts of polyvinyl chloride (PVC) resin powder, 8-12 parts of a plasticizer, 4.2-5.5 parts of a compound stabilizer, 100-180 parts of a filler, 10-30 parts of an impact modifier, 3. 5-5 parts of a foaming agent, 0.6-1 part of a processing agent, 6-20 parts of a wear-resistant regulator. The modified plastic provided by the invention can be used for producing wear-resistant floor blocks by using recycled waste polyvinyl chloride (PVC) plastics. The product has the advantages of high strength, good toughness, impact resistance, fire retardance, easy processing, weather resistance, wear resistance and low cost. The method is simple and practical, has the biggest advantage of recycling and processing the waste plastics, saves material resources, lowers production cost, and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of recycling and modification of polymer materials and the technical field of processing, and relates to a modified plastic and its preparation method and application. Background technique [0002] The floor that is used for family, office room decoration on the market is solid wood floor and composite floor usually. Solid wood flooring is made of natural wood with good texture, and composite flooring is mainly made of wood chips, sawdust, glue and plastic printing veneer. There are many deficiencies and shortcomings in the above two types of flooring: for example, solid wood flooring needs to cut down a large number of natural high-quality trees, which is not only expensive, but also destroys the ecological environment, and the laying is complicated, which is prone to mildew, decay, insects, deformation, cracking, etc.; The floor has poor appearance, high formaldehyde content, short service life, easy dama...
