Problems solved by technology

In the past, synthetic paper used high molecular polymer as the main raw material, calcium carbonate as the auxiliary raw material, and the calcium carbonate content was less than 40%, so not only the cost was relatively high, but also it depended on petroleum, and its development was limited to a certain extent.
Recently, this technology has been greatly developed. Calcium carbonate is the main raw material, with a content of up to 80%, and high molecular polymer is an auxiliary raw material, with a content of less than 30%. Through the application of various new technologies, it has both plastic and paper properties. characteristics, but the strength of this environmentally friendly paper is significantly lower than that of synthetic paper in the past

Abstract

The invention provides a method for using nylon fiber for enhancing highly-filled environment-friendly paper. The method is characterized in that 20-25 parts of high-density polyethylene, 0.5-2 parts of the nylon fiber and 0.2-0.8 part of octadecyl polyamide urea are added into an internal mixer, internally mixed to the temperature of 150 DEG C and kept for 20 minutes at the constant temperature, 75-80 parts of calcium carbonate, 0.3-1.5 parts of powdery sodium polyacrylate with the molecular weight of 3000, 0.2-1.0 part of atearic acid monoglyceride and 0.05-0.3 part of antioxidant 1010 are added into the internal mixer, internal mixing is carried out continuously till the temperature reaches 160 DEG C, and the constant temperature is kept for 20 minutes; then materials internally mixed are fed into an extruding machine, and an extruded melt is fed into a calendaring machine through a T-type die head, and rolled into sheets at the temperature of 140 DEG C to 160 DEG C; the sheets coming out of the calendaring machine are cooled to below 5 DEG C through air with the relative humidity of 50-100%; the sheets are fed into a multi-roller stretcher, preheated to 110 DEG C to 130 DEG C, and stretched through two to five sets of stretching rollers to obtain the needed environment-friendly paper.

Description

technical field [0001] The invention relates to a method for reinforcing high-filling environment-friendly paper with nylon fiber. Background technique [0002] The packaging of food, fruit, etc. has higher requirements on air permeability. Environmentally friendly paper, once known as chemical film paper, polymer paper, plastic paper, etc., is made of thermoplastic polymers (such as polyethylene, polypropylene, polystyrene) as raw materials, plus certain inorganic particles, through different production processes Different types of products are produced by equipment and processing technology. Therefore, environmentally friendly paper is the product of the combination of the paper industry and the plastics industry. In the past, synthetic paper used high molecular polymer as the main raw material, calcium carbonate as the auxiliary raw material, and the calcium carbonate content was less than 40%, so not only the cost was relatively high, but also it was dependent on petro...
