TPU-ABS (thermoplastic polyurethane-acrylonitrile-butadiene-styrene) single-sided board and preparation process thereof

Abstract

The invention discloses a TPU-ABS (thermoplastic polyurethane-acrylonitrile-butadiene-styrene) single-sided board. The TPU-ABS single-sided board comprises, in percentage by weight, 20%-30% of an outer TPU layer and 70%-80% of an ABS base layer, wherein TPU components comprise, in percentage by weight, 3%-5% of color master batch, 0.5%-1.5% of a drying agent, 0-2% of a matt agent, 1-3 permillage of a wear-resistant agent, 2-4 permillage of an anti-sticking agent, 1-5 permillage of a processing aid and the balance of TPU. The anti-sticking agent adopts erucamide or silicon oil master batch and PAI resin; the wear-resistant agent adopts silicon copper master batch. When no matt agent is added, a bright board can be prepared; when the content of the matt agent is 1%-2%, a matt board can be prepared. The TPU-ABS single-sided board with excellent wear resistance, weather resistance and stripping resistance is provided, and the preparation process of the board is also provided.

Description

technical field [0001] The invention belongs to the technical field of plastic plates, and in particular relates to a TPU-ABS single plate and a preparation process thereof. Background technique [0002] ABS resin is a general-purpose thermoplastic with excellent physical and mechanical properties, surface hardness, heat resistance and high strength. It is widely used in automotive instrument panels, home appliance casings, office supplies, and pipe profiles. TPU is a thermoplastic elastomer rubber with excellent load-bearing capacity, wear resistance, good elasticity and outstanding impact resistance. It is widely used in electronic products, household appliances, office supplies and automobiles. Using the composite structure of TPU and ABS, compared with traditional PP, PS and PET sheets, it has better low temperature resistance, high elasticity and impact resistance, and has broad application prospects in steel pallet transportation and car body interior panels. .

Problems solved by technology

However, due to the lack of adhesion between TPU and ABS, some places are easy to come off or the bond is not strong, and TPU is easy to bond with the roller during the calendering process. At present, the TPU-ABS plastic sheet with domestic performance mainly relies on Imported, widely used in BMW and other car series, the cost is high
