Problems solved by technology

The specific gravity of the traditional polypropylene foam sheet is generally 0.4-0.6g / cm3, because the surface hardness of the foam material becomes smaller, it is very easy to scratch and break, resulting in extremely poor surface effect, affecting the appearance and use
The scratch resistance of polypropylene sheets with high expansion ratio is more difficult to overcome

Abstract

The invention provides a high foaming scratch-resistant polypropylene foaming material. During production, the production raw materials comprise the following components in parts by weight: 10-60 parts of polypropylene with high melt strength, 0-70 parts of co-polypropylene, 0-50 parts of low-melting homo-polypropylene, 3-20 parts of sarin resin, 0.3-2 parts of a scratch-resistant agent, 3-10 parts of grafted PP, 3-10 parts of grafted POE, 5-20 parts of MDPE, 1-10 parts of a filling master batch, 0.3-1.5 parts of a foaming agent, 0.04-0.1.5 part of white oil and 0.02-0.04 part of an antioxidant. The foaming material is a low-density polypropylene foaming sheet, and the scratch resistance of the foaming material is far higher than that of a traditional foaming material.

Description

technical field [0001] The invention relates to the technical field of polypropylene foaming materials, in particular to a high-expansion foaming and scratch-resistant polypropylene foaming material and a preparation method thereof. Background technique [0002] In production and life, people will use composite foaming materials in various aspects such as building decoration, outdoor heat preservation, and automobile interior decoration to meet the needs of thermal insulation. In order to ensure the heat insulation effect and light weight requirements, the traditional polypropylene foam material is made more and more fluffy and light. Due to its good thermal insulation effect and lighter quality, high foam polypropylene sheet has a wide range of application requirements. The specific gravity of the traditional polypropylene foam sheet is generally 0.4-0.6g / cm3. Because the surface hardness of the foam material becomes smaller, it is very easy to be scratched and broken, res...
