Abstract

The invention provides a surface treatment method of an ABS+TPU blister packaging composite material. The method comprises the following steps that 1) an ABS+TPU composite material is placed into a drying oven for baking for 10-14 hours at the temperature of 60-80 DEG C; 2) the baked ABS+TPU composite material enters a blister packaging mold for molding, and the mold need to be preheated, so thatthe work temperate of the mold is controlled to be 60-80 DEG C; and 3) the molded product is heated and softened, so that the TPU surface of the product is heated in the environment at the temperatureof 90-110 DEG C. Compared with the prior art, the surface problems of corrugation bonding of the TPU surface, whitening, cracking and spots of the TPU surface and the like can be effectively solved.

Description

technical field [0001] The invention relates to the field of plastic-absorbing materials, in particular to a surface treatment method for ABS+TPU plastic-absorbing composite materials. Background technique [0002] The blister plastic process is mainly manufactured by absorbing the plastic on the surface of the mold after heating and softening. ABS+TPU composite material is a kind of material that is often used in the blister process at present. It is mainly used to manufacture some products such as electronic transportation trays and auto parts transportation trays. It needs to have a certain strength to carry these products. [0003] After the current ABS+TPU composite material is molded in the blister mold, the surface of the TPU surface will have surface adhesion ripples, whitening, cracking, and pitting on the TPU surface due to the attachment of the mold, which will affect the quality of the molded product. Contents of the invention [0004] In view of this, the pre...
