Embodiment 1

[0033] A preparation method of an oil-resistant and high-temperature-resistant modified polyvinyl chloride composite material, comprising the steps of:

[0034] Masterbatch preparation stage: first weigh 30gPVC and 20gBN, make the weighed sample into a masterbatch of BN / PVC (mass ratio 4:6), fully mix the two components with 500mL tetrahydrofuran, and put the mixed mixture in Ultrasonic in an ultrasonic cleaner for 5-7 hours, so that the two components in the mixture are fully mixed and evenly mixed.

[0035] 2) Masterbatch molding stage: After the ultrasonic wave is completed, use a Buchner funnel to carry out suction filtration, and the masterbatch after suction filtration is naturally air-dried under ventilated conditions, then crushed, and placed in an oven at 50-60°C for 24 hours.

[0036] 3) Take the masterbatch after drying, and gradually add PVC, PA and organotin therein, the specific proportion is PVC:BN:PA:organotin=81:10:5:4, obtain the sample, after mixing evenly, ...

Abstract

The invention discloses an oil-resistant and high-temperature-resistant modified polyvinyl chloride (PVC) composite material and a preparation method thereof. The oil-resistant and high-temperature-resistant modified PVC composite material comprises the following components in parts by weight: 60 to 90 parts of PVC powder, 5 to 25 parts of boron nitride (BN) powder, 1 to 25 parts of nylon and 1 to5 parts of organic tin. The preparation method comprises the following steps: (1) a mother material preparation stage: weighing a certain amount of PVC and BN to prepare the mother material of BN/PVC, mixing the mother material by using tetrahydrofuran and putting the mixture into an ultrasonic cleaner; (2) a mother material forming stage: after ultrasonic treatment, performing suction filtrationby a Buchner funnel, naturally air-drying, crushing and drying; (3) mixing the dried mother material and other raw materials uniformly according to the proportion, mixing in a Happ mixing machine, crushing, performing mold pressing, performing hot cutting and preparing samples. According to the oil-resistant and high-temperature-resistant modified PVC composite material and the preparation methodthereof, which are provided by the invention, the technical problems that the conventional PVC composite material does not resist high temperature and oil and is liable to decompose, short in servicelife, complex in preparation process, high in cost and the like are solved.

Description

technical field [0001] The invention relates to the field of cable materials, in particular to an oil-resistant and high-temperature-resistant modified polyvinyl chloride composite material and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is a general-purpose plastic, and it is the second largest synthetic plastic in the world. Since the development of new polymer materials in my country, with the development of polymers, PVC composite materials rank first in my country's synthetic plastics First. Polyvinyl chloride has many excellent properties, such as: cheap price, good transparency, difficult to burn and corrosion resistance. The original polyvinyl chloride only has the basic characteristics of polyvinyl chloride, but by adding various additives and using a variety of The processing and forming method can prepare various soft or hard products with different properties and a wide range of uses. In some special occasions, such as in ...
