Embodiment 1

[0027] Thoroughly mix the base resin and filler oil evenly. After the filler oil is completely absorbed by the resin, add tackifiers, mineral fillers, coupling agents, processing aids, composite light stabilizers and other components in the following proportions by weight: Mix well in a mixer. The mixed materials are sent into the twin-screw extruder by the feeder, the temperature of the twin-screw extruder is set at 220°C, the feeding frequency is 20 Hz, and the speed of the main engine is 25 Hz. Raw materials are sheared and mixed at high speed by twin-screws, extruded by the machine head, drawn, air-cooled, pelletized, dried and packaged.

Abstract

The thermoplastic elastomer for filming Dacron cloth used as box lining, sportswear lining, etc. consists of matrix resin 10-80 wt%, filler oil 0-60 wt%, tackifier 5-50 wt%, mineral filler 0-25 wt%, coupling agent 0.1-0.8 wt%, machining assistant 0.1-2 wt%, and composite stabilizer 0.1-2 wt%. By means of the improved recipe and preparation process, the present invention solves the problem of adhering non-polar matrix with Dacron or other polar chemical fiber fabric, so that the film on the Dacron material has high peeling strength, soft and comfortable handing, high weather resistance, and high acid and alkali resistance and other advantages.

Description

technology field. [0001] The invention relates to the field of polymer materials, in particular to a thermoplastic elastomer coated with polyester, mainly coated with commonly used chemical fiber cloth such as polyester to be used as a lining material for luggage and sports clothes. Background technique [0002] For the coating process of cloth, the polymer materials currently used mainly include polyethylene (PE), polyvinyl chloride (PVC), polyvinyl acetate (EVA), polyurethane (TPU) and the like. Polyethylene material has the advantages of low price, good weather resistance and thermal stability, but it has poor hand feeling, so it is rarely used at present. Polyvinyl chloride material has been widely used in the production of artificial leather, but PVC has poor weather resistance, especially low temperature performance. At the same time, the use of plasticizers and other components in PVC materials and formula systems does not meet the current consumption concepts of non...
