Embodiment 1

[0029] Example 1: A kind of propylene-based plastic compatibilizer for automobile wire and its preparation method

[0030] Preparation method: After the materials in the raw material formula are prepared according to their respective weight parts, they are first sent to a high-speed mixer and kneaded for 20 to 60 minutes to obtain a mixture, and then the mixture is sent to a twin-screw extruder for extrusion For granulation, the extrusion temperature is 170~220°C, and the screw speed is 250~360rpm.

[0031] Then, Comparative Example 1 and Comparative Example 2 were prepared using similar raw material formulations and preparation methods. The difference was that Comparative Example 1 and Comparative Example 2 did not add propylene-based elastomers, and Comparative Example 1 added homopolypropylene. Examples and comparative examples are prepared by the preparation method of the present invention. See Table 1 below for the proportions of parts by weight of Example 1, Comparative...

Abstract

A car wire propenyl plastic compatilizer and a preparation method thereof are provided, the car wire propenyl plastic compatilizer is prepared by blending raw materials in weight ratio in the formulation, and granulating with an extruder, the car wire propenyl plastic compatilizer is characterized by comprising the following raw material formulation by weight: 40 to 55 parts of a propenyl elastomer, 40 to 50 parts of polypropylene, 10 to 20 parts of metallocene polyethylene, 5-10 parts of KN resin, 0.3-1 part of a graft monomer, 0. 05 to 0.1 part of an initiator, 0.05 to 0.1 part of an antioxidant and 0.1 to 0.5 part of a dispersing agent. The raw materials in the raw material formulation are dosed in accordance with respective weight fractions, then sent into a high-speed mixer for blending for 20 to 60 minutes to obtain a first mixture, and the mixture is fed into a twin-screw extruder for extrusion granulation, the extrusion temperature is 170-220 DEG C, and the screw rotation speed is 250-360 rpm. After the addition of the car wire propenyl plastic compatilizer into a car wire, and under the premise of ensuring that various performance parameters of the car wire can meet ISO6722 standards, excellent compatibility, heat aging resistance, scratch resistance and processability performance can be achieved.

Description

technical field [0001] The invention relates to the field of high molecular polymers, in particular to an acrylic plastic compatibilizer for automobile wires and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, cars have been closely linked with our daily lives. Taking advantage of the opportunity of the rapid development of the automobile industry, my country's automobile wire and cable industry has also developed rapidly in recent years. In 2012, the sales volume of the domestic wire harness market was about 80 billion yuan, of which the cable materials used for insulating sheaths were about 5 billion yuan. It can be seen that the market capacity of cable materials for automotive wires is very considerable. [0003] Wires and cables are one of the important components of automotive electrical appliances. Automobile wires are different from ordinary wires and cables. They are specially designed for t...
