Problems solved by technology

Generally, the inorganic mineral powder is treated with a coupling agent, and then added with paper fibers and other additives and resins, and then processed and formed. However, the strength of general synthetic paper is not high, and it is prone to damage and tear. Cracks will affect the performance of the paper quality during printing, and there will be damage

Embodiment Construction

[0021] The weight proportion of table 1 embodiment 1~embodiment 3

[0022]

[0023] In the foregoing embodiment, polyethylene is high-density polyethylene, plant fiber is methyl cellulose, inorganic filler is ground calcium carbonate, particle size is 100~500 mesh, and surfactant is sodium dodecylbenzenesulfonate , the antioxidant is butylated hydroxyanisole.

[0024] The preparation method is:

[0025] S1: Dry polyethylene, polypropylene, plant fibers, and inorganic fillers at 85°C for 4 hours, and set aside;

[0026] S2: Polyethylene, polypropylene, plant fiber, aluminum silicate fiber, cellulose, ethylene-acrylic acid copolymer, agar, alum, inorganic filler, calcium stearate, zinc stearate, surfactant, antioxidant in Mix at 85°C for 15 minutes;

[0027] S3: sending the mixture obtained in step S2 into a twin-screw extruder for extrusion and granulation;

[0028] S4: Perform blow molding on the pellets obtained in step S3, and then cut them.

[0029] In step S3, the ...

Abstract

The invention provides synthetic paper, and particularly relates to synthetic paper having high tensile strength, belonging to the technical field of paper making. The synthetic paper comprises the following components in parts by weight: 20-30 parts of polyethylene, 20-30 parts of polypropylene, 40-60 parts of plant fiber, 5-8 parts of aluminum silicate fiber, 10-20 parts of cellulose, 5-10 parts of ethylene-acrylic acid copolymer, 3-6 parts of agar, 3-6 parts of alum, 10-15 parts of inorganic filler, 5-7 parts of calcium stearate, 2-3 parts of zinc stearate, 2-3 parts of surfactant and 2-3 parts of antioxidant. The tension stress of the synthetic paper made by the invention can reach 5 Kg / 15mm (in the transverse direction) and 12 Kg / 15mm (in the longitudinal direction), and the breaking strength can reach 10 Kg / cm<2> or above.

Description

technical field [0001] The invention provides a synthetic paper, in particular relates to a synthetic paper with high tensile strength, and belongs to the technical field of papermaking. Background technique [0002] Synthetic paper is made of polyolefin resin and inorganic filler as the main raw materials through extrusion process, and it is a multi-functional material with both plastic and paper characteristics. Synthetic paper is a new type of plastic material product, and it is also an environmentally friendly product. It has the characteristics of light specific gravity, high strength, durability, economy and environmental protection. Synthetic paper has a history of more than 30 years abroad, especially in developed countries such as the United States, Japan, and Canada. With the strengthening of global environmental protection awareness, ordinary fiber paper has caused a lot of pollution, which has accelerated the development of synthetic paper, and the continuous em...
