Embodiment 1

[0024] In parts by weight, add 60 parts of TPO, 2 parts of reactive TPO (r-TPO), 1 part of polypropylene, 6 parts of polyethylene, 1 part of light stabilizer, 8 parts of foaming agent, fluorescent substance: 5 parts, attapulgite: 40 parts, lubricant: 1 part, adsorbent: 4 parts, flame retardant: 10 parts. The TPO foam material can be obtained after mixing and foaming and keeping it at 120°C for 3 hours.

Embodiment 2

[0026] In parts by weight, add 60 parts of TPO, 2 parts of reactive TPO (r-TPO), 2 parts of polypropylene, 5 parts of polyethylene, 1 part of light stabilizer, 10 parts of foaming agent, fluorescent substance: 5 parts, attapulgite: 50 parts, lubricant: 1 part, adsorbent: 4 parts, flame retardant: 10 parts. The TPO foam material can be obtained after mixing and foaming and keeping it at 120°C for 3 hours.

Embodiment 3

[0028] In parts by weight, add 60 parts of TPO, 2 parts of reactive TPO (r-TPO), 2 parts of polypropylene, 5 parts of polyethylene, 2 parts of light stabilizer, 12 parts of foaming agent, fluorescent substance: 5 parts, attapulgite: 60 parts, lubricant: 1 part, adsorbent: 4 parts, flame retardant: 10 parts. The TPO foam material can be obtained after mixing and foaming and keeping it at 120°C for 3 hours.

[0029] The TPO prepared by the formula of the invention has high melt strength, and the temperature-viscosity response curve is gentler than that of a single TPO system, which meets the requirements of vacuum suction molding. And it has the advantages of low density and good air permeability.

Abstract

A foamed TPO material is characterized in that the produced TPO material is the foamed TPO material with the characteristics of low density, excellent gas permeability and the like. The TPO material comprises the following components in parts by weight: 60-100 parts of TPO, 0.05-40 parts of reactive TPO(r-TPO), 0.05-3 parts of a light stabilizer, 3-15 parts of a crosslinking agent, 3-15 parts of afoaming agent, 0.05-100 parts of attapulgite, 0.05-5 parts of a lubricant, 0.05-10 parts of an adsorbent and 0.05-100 parts of a flame retardant. The attapulgite-modified foamed TPO material producedin the invention has a foaming characteristic and has the advantages of low density, good gas permeability and the like, and other properties of the TPO material are not affected. Compared with the prior art, the attapulgite-modified foamed TPO material provided by the invention has the advantages as follows: the produced TPO material is the attapulgite-modified foamed TPO material and has the characteristics of excellent various properties and the like.

Description

technical field [0001] The invention relates to a TPO material, in particular to an attapulgite modified foamed TPO material. Background technique [0002] With the rapid development of society, people's demand for polymer materials is increasing day by day, and the research on polymer materials is also deepening step by step. Polymer materials including plastics, rubber, fibers, etc. have great applications in various fields, especially TPE elastomers. TPO material is a kind of TPE material and is a thermoplastic elastomer. It is generally made of EPDM rubber mixed with other plastics. It has both the elasticity of rubber and the plasticity of plastic. It has excellent performance and is convenient for molding processing and secondary recycling. At present, TPO materials are widely used in automobile interior decoration, simple decoration in the construction field, and waterproof materials. [0003] TPO material has excellent performance, and its appearance is natural co...
