Embodiment 1

[0027] Add 100 parts of LLDPE with a melt flow rate of about 5g / 10min, 2 parts of HDPE, Japanese Ube PLX-19, and 0.1 part of dicumyl peroxide into the high-speed mixer, mix for 5 minutes, and then add 1 part of PE starch and charcoal Add 1 part of black and 1 part of magnesium hydroxide Mg(OH)2 into a high-speed mixer, mix for 6 minutes, and then extrude and granulate at a temperature of 170-220℃ to obtain a polyethylene composite material. The performance indicators are shown in the table 1.

Embodiment 2

[0029] Add 100 parts of LLDPE with a melt flow rate of about 6g / 10min, 4 parts of HDPE, Ube PLX-19, 0.5 parts of dicumyl peroxide into the high-speed mixer, mix for 6 minutes, and then add 2 parts of PE starch, charcoal Add 2 parts of black and 2 parts of magnesium hydroxide Mg(OH)2 into a high-speed mixer, mix for 6 minutes, and then extrude and granulate at a temperature of 170-220℃ to obtain a polyethylene composite material. The performance indicators are shown in the table 1.

Embodiment 3

[0031] Add 100 parts of LLDPE with a melt flow rate of about 7g / 10min, 6 parts of HDPE, Japanese Ube PLX-19, and 1 part of dicumyl peroxide to the high-speed mixer, mix for 6 minutes, and then add 3 parts of PE starch and carbon Add 3 parts of black and 3 parts of magnesium hydroxide Mg(OH) into a high-speed mixer, mix for 6 minutes, and then extrude and granulate at a temperature of 170-220℃ to obtain a polyethylene composite material. The performance indicators are shown in the table 1.

Abstract

A novel high-strength composite material and a preparation method thereof belong to a polyvinyl structural composite material and a preparation method thereof. The novel high-strength composite material is prepared by the following materials in parts by weight: 100 parts of linear LDPE ( low density polyethylene), 2 to 10 parts of HDPE (high density polyethylene), 1 to 5 parts of PA (polyamide) (nylon), 0.1 to 2 parts of a strong oxidant, 1 to 5 parts of PE starch, 1 to 8 parts of carbon black, and 1 to 5 parts of a fire retarding agent. The novel high-strength composite material provided by the invention is excellent in comprehensive service performance, can improve material rigidity, toughness and environmental stress crack resistance. The novel high-strength composite material is excellent in mechanical processing capability, runnability, thermal stability, and impact resistance, and also is relatively good in wearing resistance, environmental stress crack resistance, heat resistance, rigidity, antistatic performance, degradability, flame retardancy and the like.

Description

technical field [0001] The invention relates to the field of material technology, in particular to a polyethylene structural composite material and a preparation method. Background technique [0002] In recent years, material technology, as one of the key fields in the national science and technology development plan, is the key technology of modern industry. Composite materials are composed of two or more materials with different properties, through physical or chemical methods, macroscopically (microscopically) composed of materials with new properties, in aerospace, shipbuilding, automobile industry and chemical, textile and machinery manufacturing , and even have a wide range of applications in the military field. With the rapid development of my country's national economy, all walks of life have invested heavily in the application of composite materials, making the current types, specifications, and performance of composite materials far from meeting the needs of deve...
