Embodiment Construction

[0022] 1. Raw material ratio

[0023]

[0024] Among the above raw materials, polar resin 1901 and HS1-008 can be replaced by other SEBS-g-MAH or EPDM-g-MAH, POE-g-MAH, PP-g-MAH of the same type;

[0025] Mineral oil KN4006 can be replaced by other saturated linear paraffin oil or naphthenic oil with a flash point higher than 200°C, such as 500N of Ssangyong Company of South Korea;

[0026] Antioxidant 1076 can be replaced by other similar antioxidant 1010, antioxidant 168;

[0027] The mineral filler is one or a mixture of calcium carbonate, talcum powder, gypsum powder, asbestos powder, clay, barium sulfate, mica powder, kaolin;

[0028] The auxiliary agent 1753 can be replaced by other appropriate amount of fatty acid, fatty acid amide, polysilicone.

[0029] 2. Extrusion processing

[0030] Take the raw material components according to the above-mentioned proportions, mix the base resin SEBS and mineral oil fully and evenly,

[0031] Then add polar resin, ternary co...

Abstract

The invention relates to a thermoplastic elastomer for second encapsulating nylon, comprising: 20-30 portions of matrix resin SEBS, 10-20 portions of polarity resin, 10-15 portions of mineral oil, 0.1-1 portions of antioxidant and selectively adding 10-15 portions of mineral filler and 0.1-1 portions of processing agents. The raw material of the thermoplastic elastomer does not contains coupling agent and the injection moulding temperature is low during second encapsulating nylon composites and the cooling time of the forming is reduced and the production efficiency is increased. The second encapsulation between the obtained end product and nylon is firm and the shaping is good, with better hand feeling compared to the present product with lower hardness.

Description

【Technical field】 [0001] The invention relates to the field of polymer materials, in particular to a thermoplastic elastomer used for secondary injection bonding of nylon materials. 【Background technique】 [0002] Nylon is produced by polycondensation of diamines and dibasic acids, or by self-polymerization of lactams. Nylon is the first thermoplastic resin that can withstand loads. It has good comprehensive properties and is a widely used engineering plastic. However, products made of nylon materials, especially those used in the field of tools that are in direct contact with the human body (such as tool handles, car gear levers, etc.), have hard and smooth surfaces, and often slip from the hands of users during use. ,cause inconvenience. Therefore, wrapping a layer of soft glue on the surface of nylon to reduce the smoothness of the product has become the first choice to solve this defect. Usually, the industry adopts the method of sticking a layer of thermoplastic elast...
