Problems solved by technology

Although the thermoplastic elastomer material is firmly bonded to common nylon, since the tackifier in the elastomer has adopted at least one of nylon polymers and polar resins, if the tackifier adopts nylon polymers, However, there are no other ingredients in the material itself that increase the compatibility of nylon polymers and matrix resins in the formula

Embodiment 1

[0038] Elastomer A1 was prepared as follows:

[0039] 1. Take raw materials according to the weight percentage distribution ratio of Example 1 in Table 1;

[0040] 2. Put the matrix resin into the mixer, inject the softening plasticizer into the mixer through the spray device, spray and mix while spraying;

[0041] 3. After the softening plasticizer is completely absorbed by the matrix resin, add adhesion promoters, compatibilizers, mineral fillers, stabilizers, and lubricants and mix well;

[0042] 4. Put the mixed materials above into a twin-screw extruder to extrude and granulate. The temperature of the twin-screw extruder is set at 250°C, the feeding frequency is 20 Hz, and the speed of the main machine is 300 rpm.

[0043] Thermoplastic elastomer and high glass fiber filled nylon (25% glass fiber content) including bonding: uniformly spray a surface treatment agent on the predetermined bonding surface of nylon, and then complete the secondary injection molding process wi...

Abstract

The invention provides a thermoplastic elastomer capable of coating and bonding with a glass fibre filling reinforced nylon, comprising the following raw materials in percentages by weight: 20-40% of matrix resin, 5-45% of softened plasticizer, 15-30% of adhesion promoter, 0-30% of mineral filler, 15-35% of compatilizer, 0-1% of lubricant and 0-2% of stabilizer, wherein the adhesion promoter includes a first adhesion promoter and a second adhesion promoter; the first adhesion promoter is at least one of a polyamide thermosol and a nylon polymer; and the second adhesion promoter is a mixture of a thermoplastic polyurethane elastomer and a polyether block amide copolymer; meanwhile, the invention further provides a method for preparing the elastomer. The elastomer is far higher than contrast products in tensile strength at break, tensile elongation at break and peel strength. The elastomer of the invention has good mechanical property.

Description

technical field [0001] The invention belongs to the field of macromolecular materials, and relates to a thermoplastic elastomer which can be coated and bonded with glass fiber-filled and reinforced nylon and a preparation method thereof. Background technique [0002] Thermoplastic elastomer is a new type of material that combines the excellent properties of thermoplastics and rubber. It can be molded alone, or it can be firmly coated on PP by secondary injection molding or extruder co-extrusion without any binder. , PE, PS, ABS, PC and other plastic materials, so as to make the inner hard polymer skeleton, and the outer layer is a soft elastomer product. Therefore, it is widely used in the handles of households, toys, and various tools to achieve elastic, rigid, and non-slip handles, as well as the functions of heat insulation, shock absorption, damping, and insulation, which can relieve user fatigue. Due to the different raw material formulations and proportions of thermop...
