Problems solved by technology

[0003] Traditional PVC materials have poor thermal stability, become hard and brittle at low temperatures, tend to soften and relax at high temperatures, and are prone to produce toxic and harmful gases when burned. Therefore, TPV is gradually replacing PVC in many fields; although TPU materials have many advantages, the heat resistance of materials , high temperature and water resistance are poor, and the cost is high. Therefore, TPV has certain advantages in terms of comprehensive performance and comprehensive cost

preparation example Construction

[0025] The preparation method of high-performance TPV composite material of the present invention specifically comprises the following steps:

[0026] 1) Put the components of the above-mentioned modified TPV material into the hopper according to their ratio;

[0027] 2) Adjust the position of the inner die opening and the outer die opening of the extruder die head to avoid eccentricity of the TPV composite wire;

[0028] 3) Set the temperature of each section of the screw extruder to be controlled at 180°C in the feed section, 190°C in the compression section, and 200°C in the homogenization section. The temperature of the die head is set at 210°C. Through the inner and outer die openings of the die head, the modified TPV material enters the screw extruder, and the pellets are driven by the screw extruder to move toward the head. After three-stage heating, the temperature of the pellets at the outlet of the die head reaches 200 ℃, enter the extruder die head in a molten stat...

Abstract

The invention relates to a high-performance TPV composite material. According to the high-performance TPV composite material, silk threads or cotton threads as a core part to serve as an internal support of a wire rod, and the outer surface is coated with a modified TPV material; the TPV material is subjected to modification treatment, the plasticity and flexibility of the material can be improvedby adding a plasticizer, and the elongation at break of the formed material is improved. Through modification treatment and surface coating, the composite material disclosed by the invention has excellent ageing resistance, good weather resistance and heat resistance, light specific gravity, uniform appearance quality, high surface grade and good hand feeling, and the fabric is prepared through aweaving process and can be widely applied to the fields of shoe materials, clothes, sun-shading fabrics, outdoor tents and the like.

Description

technical field [0001] The invention relates to the technical field of TPV composite materials, in particular to a high-performance TPV composite material. Background technique [0002] The Chinese name of TPV is thermoplastic dynamic vulcanized rubber or thermoplastic vulcanized elastomer, which is an elastomer material composed of highly vulcanized rubber particles dispersed in a continuous plastic phase. The physical properties and functional properties of TPV at room temperature are similar to thermosetting resins. At high temperatures, it has the melting flow and repeated processing characteristics of thermoplastics, and can be processed quickly and conveniently. TPV has good elasticity and resistance to compression deformation, excellent aging resistance, good weather resistance, heat resistance, excellent ozone resistance and ultraviolet resistance, and its oil resistance and solvent resistance are comparable to general-purpose neoprene rubber; use The advantages of ...
