Problems solved by technology

However, the addition of a large amount of calcium carbonate will also reduce the tensile and tear strength of the composite material, which in turn will limit the use of the composite material
Studies have shown that calcium carbonate is used as a polyolefin filler, and its particle size greatly affects the performance of composite materials. The smaller the particle size, the better the performance, but the difficulty of dispersion is high, and the requirements for technical equipment are high. The smaller the particle size, the more unfavorable the particle size Dispersion in the numerical collective, the particles are prone to agglomeration, which will reduce the performance of the material

Abstract

The present invention relates to composite material, and is especially one kind of composite inorganic and organic polyethylene material with high dispersivity, low cost, high tensile strength, great elongation at break and high tearing strength. The technological scheme of the present invention is that the composite polyethylene material consists of polyethylene, calcium carbonate, coupling agent and surfactant as well as magnesium carbonate. It is used as packing material.

Description

Technical field: [0001] The invention relates to an inorganic and organic composite material, especially a polyethylene composite material. Background technique: [0002] Calcium carbonate and polyethylene composite material is a new type of inorganic-organic material, which is usually prepared by injection molding or extrusion. The cost of materials can be reduced. However, the addition of a large amount of calcium carbonate will also reduce the properties such as tensile and tear strength of the composite material, which in turn will limit the use of the composite material. Studies have shown that calcium carbonate is used as a polyolefin filler, and its particle size greatly affects the performance of composite materials. The smaller the particle size, the better the performance, but the difficulty of dispersion is high, and the requirements for technical equipment are high. The smaller the particle size, the more unfavorable the particle size Dispersion in the numerica...
