Problems solved by technology

However, some products with complex structures and strange shapes still have poor lagging effect at the edges. The reason is that the existing nylon lagging materials have insufficient fluidity and cohesive force, and it is not easy to wrap products with complex structures and strange shapes. at the edge of

Embodiment 1

[0039] This embodiment is to prepare a kind of TPE nylon encapsulated pellet with high fluidity and high cohesive force, comprising the following steps:

[0040] S1: Preparation of raw materials: Weigh 10 parts of styrene elastomer, 20 parts of white oil, 5 parts of maleic anhydride grafted polystyrene elastomer, 5 parts of maleic anhydride grafted polyethylene, and 5 parts of maleic anhydride grafted polyethylene by weight. 10 parts POE, 10 parts polypropylene, 10 parts calcium carbonate, spare;

[0041] S2: Blending of raw materials: Add the raw materials of each component prepared in step S1 into the heating type high-speed melt blending machine according to the predetermined order and speed for blending to form a TPE nylon encapsulation premix. The specific steps are:

[0042] S2-1: Start the heating type high-speed melt blender to raise the temperature to 35°C, add styrene elastomer, maleic anhydride grafted polystyrene elastomer and white oil, control the stirring speed ...

Embodiment 2

[0049] Example 2: This example also prepares a high fluidity and high cohesion TPE nylon-encapsulated granule, and its preparation method is consistent with Example 1. Calculated as: 12 parts of styrene elastomer, 25 parts of white oil, 6 parts of maleic anhydride grafted polystyrene elastomer, 6 parts of maleic anhydride grafted polyethylene, 12 parts of maleic anhydride grafted POE, 12 parts of polypropylene parts, 12 parts of calcium carbonate.

Embodiment 3

Abstract

The invention discloses a TPE nylon rubber-coated particle material with high fluidity and high binding power and a preparation method thereof. The TPE nylon rubber-coated particle material comprises the following components by weight: 10-20 parts of a styrene elastomer, 20-40 parts of white oil, 5-10 parts of a maleic anhydride grafted polystyrene elastomer, 5-10 parts of maleic anhydride grafted polyethylene, 10-20 parts of maleic anhydride grafted POE, 10-20 parts of polypropylene and 10-20 parts of calcium carbonate. The preparation method comprises the steps of raw material preparation, raw material blending, secondary rubber mixing, plastication extrusion, cooling granulation and the like, and by introducing the new material maleic anhydride grafted POE, the adhesion and compatibility of a polar material and a non-polar material are improved, and the fluidity of the system and the adhesion of the material and nylon are improved. The nylon rubber-coated particle material can improve the surface coating degree and adhesion strength of a product, and is suitable for products with complex structures and peculiar shapes.

Description

technical field [0001] The invention relates to a TPE nylon-encapsulated pellet with high fluidity and high cohesive force and a preparation method thereof. [0002] technical background [0003] Nylon, the first synthetic fiber to appear in the world, is widely used in the fields of textile and machinery manufacturing due to its excellent wear resistance. In addition, due to the characteristics of high heat resistance, high rigidity, high strength and good insulation of nylon and its modified materials, it is often used to make shells, handles, accessories, etc. of electric tools. In order to improve the performance of power tools of nylon products, it is generally necessary to cover the surface of the nylon material with a coating material, that is, to perform secondary injection overmolding. The covering material of the existing electric tools (nylon products) generally adopts thermoplastic elastomer (Thermoplastic Elastomer), referred to as TPE. Its products not only ha...
