Example Embodiment

[0027] Example 1:

[0028] Weigh the SEBS with a weight ratio of 20% (the following are all weight ratios) and pour it into the blender. Slowly add 5% of the white oil to the SEBS. Stir slowly while dripping until the dripping is complete. Stir evenly, and then press TPU 55%, ABS 15%, compatibilizer 4%, 1010 / 168 0.2 / 0.1%, EBS 0.4%, E525 0.3%, weigh it, pour it into a mixer and mix well. The mixed materials are added to the hopper of the twin-screw extruder, melt blended, extruded and granulated into composite materials. Among them, the temperature settings of each heating zone of the screw are: temperature in zone one: 185°C; zone two: 190°C; zone three: 190°C; zone four: 190°C; head: 185°C; residence time 1~2min. The pressure is 14MPa.

Example Embodiment

[0029] Example 2:

[0030] Weigh the SEBS at 20% by weight (the following are all weight ratios) and pour it into the blender. Add 10% white oil slowly to the SEBS. Stir slowly while dripping until the dripping is complete. Stir evenly, then press TPU. 50%, ABS 15%, compatibilizer 4%, 1010 / 168 0.2 / 0.1%, EBS 0.4%, E525 0.3%, weigh it, pour it into a mixer and mix well. The mixed materials are added to the hopper of the twin-screw extruder, melt blended, extruded and granulated into composite materials. Among them, the temperature settings of each heating zone of the screw are: temperature in zone one: 185°C; zone two: 190°C; zone three: 190°C; zone four: 190°C; head: 185°C; residence time 1~2min. The pressure is 14MPa.

[0031] Example 3:

[0032]Weigh the SEBS with a weight ratio of 20% (the following are all weight ratios) and pour it into the blender. Add 15% white oil slowly to the SEBS. Stir slowly while dripping until the dripping is complete. Stir evenly, and then press TPU. 45%, ABS 15%, compatibilizer 4%, 1010 / 168 0.2 / 0.1%, EBS 0.4%, E525 0.3%, weigh it, pour it into a mixer and stir evenly.

Abstract

The invention discloses a soft plastic used for coating ABS material and a preparation method thereof. The soft plastic comprises the components according to the weight percentage: 30-60% of PU, 5-25% of white oil, 15-25% of SEBS, 10-20% of ABS resin, 3-5% of compatilizer, 0.2-0.4% of antioxidizer and 0.5-1% of other accessory ingredients. The invention has the advantages that the raw materials are environment-friendly and sanitary, so that the prepared soft plastic is sanitary and environment-friendly; besides realizing high intensity and elasticity as well as good abrasion resistance, oil proof property, low temperature resistance and aging resistant performance, the soft plastic has high flexibility and comfort; due to good adhesive bonding property with the ABS material, the coating effect between the soft plastic and the ABS base material can be improved. The preparation method provided by the invention is simple in technique.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a soft glue for covering ABS materials and a preparation method thereof. Background technique [0002] ABS (acrylonitrile-butadiene-styrene copolymer) resin is currently one of the polymers with the largest output and the most widely used. It organically unifies the various properties of PS, SAN, and BS, and has both toughness and hardness. , excellent mechanical properties of rigid phase equilibrium. It has excellent impact strength, dimensional stability, electrical properties, wear resistance, chemical resistance, dyeability, good molding and mechanical processing, and is widely used in the automotive industry, home appliances, electrical and electronic industries, toys, daily necessities, machinery industry and other fields. [0003] Through overmolding technology, compounding thermoplastic elastomer with ABS matrix can not only make the surface of ABS products fu...
