Problems solved by technology

Today's pillow products mostly use sponge materials and natural rubber, but sponge materials are difficult to clean, easy to breed bacteria, and are not conducive to people's health; while natural rubber is difficult to process, difficult to recycle, and has a strong smell
Due to the excellent elasticity and air permeability of TPE, some TPE pillow products have appeared on the market, but TPE pillows are heavier than sponge pillows. Most manufacturers reduce the specific gravity of the material by adding foaming agents. The requirements are very high, and the foaming agent is sensitive to the injection molding process and temperature, which is difficult to control, which leads to uneven product quality, and the nozzle material cannot be recycled.

preparation example Construction

[0060] The present invention also provides a preparation method of the thermoplastic elastomer composition, comprising the steps of:

[0061] Mixing the hollow glass microspheres, mineral oil and coupling agent to prepare mixture A;

[0062] The mixture A and the styrene block copolymer described were mixed.

[0063] By adding step by step, the hollow glass microspheres, mineral oil and coupling agent are mixed first, which is equivalent to treating the surface of the hollow glass microspheres, which is beneficial to improve the hollow glass microspheres and the styrene block. The compatibility between the copolymers and the improvement of the dispersibility of the hollow glass microspheres in the thermoplastic elastomer composition are beneficial to the performance balance of each part and can reduce the explosion rate of the hollow glass microspheres.

[0064] In one of the embodiments, the formulation of the thermoplastic elastomer composition contains thermoplastic resin ...

Abstract

The invention relates to a thermoplastic elastomer composition as well as a preparation method and application thereof. The thermoplastic elastomer composition is prepared from the following raw materials in parts by weight: 15-45 parts of a styrene block copolymer; 45 parts to 80 parts of mineral oil; 5 to 30 parts of hollow glass beads; and 0.1 to 2 parts of a coupling agent; the real density of the hollow glass beads is less than or equal to 0.6 g / cm < 3 >. The thermoplastic elastomer composition is light, soft, environment-friendly, recyclable, easy to process, high in strength, good in rebound resilience and not prone to bacterium breeding, and can be used for preparing pillows, mattresses, seat cushions, back cushions, ground mats and other daily necessities.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a thermoplastic elastomer composition and its preparation method and application. Background technique [0002] Thermoplastic Elastomer (Thermoplastic Elastomer, TPE) is a kind of elastomer that has the elasticity of rubber at room temperature and can be plasticized at high temperature. It is also called artificial rubber or synthetic rubber. It has the high elasticity, aging resistance and oil resistance of traditional cross-linked vulcanized rubber. It has various excellent performances such as anti-corrosion resistance, and at the same time, it has the characteristics of convenient processing and wide processing methods of ordinary plastics. TPE can be produced by conventional processing methods such as injection molding, extrusion, blow molding, etc., and finished products can be prepared without vulcanization, which simplifies the processing process, reduces energy consumpti...
