Abstract
A high-density polyethylene composite material comprises the following raw materials in percentage by mass: 50-70 parts of high-density polyethylene, 10-20 parts of linear low-density polyethylene, 10-20 parts of carbon fiber powder, 3-6 parts of nano diamond powder, 5 parts of magnesium oxide, 2-5 parts of di-tert-butyl hexane peroxide, 2-4 parts of dibutyltin maleate and 10101-2 parts of antioxidant. The invention has the beneficial effects that: the high-performance and tensile-resistant polyethylene composite material is prepared.
Description
Technical Field
The invention belongs to the technical field of adhesive films, and particularly relates to a high-density polyethylene composite material and a production process thereof.
Background
Polyethylene is a thermoplastic resin prepared by polymerizing ethylene, and also comprises a copolymer of ethylene and a small amount of α -olefin in industry, the polyethylene is odorless and nontoxic, feels like wax, has excellent low-temperature resistance (the lowest use temperature can reach-100 to-70 ℃), good chemical stability, can resist corrosion of most acid and alkali (cannot resist acid with oxidation property), is insoluble in common solvents at normal temperature, and has small water absorption and excellent electrical insulation.
However, the tensile strength of polyethylene materials is not good, and even the high-density polyethylene with the highest tensile strength in polyethylene is insufficient, so that the design of a high-density polyethylene composite material has a very wide market prospect.
Disclosure of Invention
In view of the above problems, the present invention provides a high density polyethylene composite material and a process thereof, wherein the high density polyethylene has excellent tensile strength, is durable in use, and has a wide application field and application market.
The technical scheme adopted by the invention for solving the technical problems is as follows: a high-density polyethylene composite material comprises the following raw materials in percentage by mass: 50-70 parts of high-density polyethylene, 10-20 parts of linear low-density polyethylene, 10-20 parts of carbon fiber powder, 3-6 parts of nano diamond powder, 3-5 parts of magnesium oxide, 2-5 parts of di-tert-butyl hexane peroxide, 2-4 parts of dibutyltin maleate and 10101-2 parts of antioxidant.
The preparation steps are as follows:
(1) mixing the high-density polyethylene, the linear low-density polyethylene, the carbon fiber powder, the nano diamond powder and the magnesium oxide together at the temperature of 80-100 ℃ for 10-20min to prepare a rubber compound;
(2) adding di-tert-butyl hexane peroxide, dibutyltin maleate and an antioxidant 1010 into the rubber compound prepared in the step 2, and mixing at the temperature of 110-130 ℃ for 10-20min to prepare a material to be extruded;
(3) and putting the material to be extruded into a granulator to obtain a finished product of the high-density polyethylene composite material.
The strength of the whole material can be greatly improved by adding the nano diamond and the carbon fiber powder into the high-density polyethylene, and the toughness of the material is improved by adding the linear low-density polyethylene into the high-density polyethylene, so that the high-performance material is prepared.
The invention has the beneficial effects that: the high-performance and tensile-resistant polyethylene composite material is prepared.
