Embodiment Construction

[0031] In the 5 embodiments of the present invention described in the table below, nano-layered silicate and coated red phosphorus are used as flame retardants, borates are used as char-forming agents, zinc oxide whiskers are used as antistatic agents, and organic Silicon surfactant and ethylene-vinyl acetate copolymer, ethylene-acrylate copolymer are auxiliary agents, but the examples should not be construed as limiting the scope of the present invention.

[0032]

[0033]

[0034] The process step of above-mentioned embodiment is as follows:

[0035] 1. Measure and weigh linear polyethylene, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, and layered silicate according to the proportion, and then add low-molecular polyethylene wax and antioxidant Agent, zinc stearate are weighed properly, mix uniformly, add twin-screw extruder and granulate into nanocomposites for subsequent use;

[0036] 2. Put the remaining unmeasured components into the high-spee...

Abstract

The invention discloses a natural color, flammable and antistatic polyolefin master batch, pertaining to the field of the preparation technology of master batches for the engineering plastic modification. The master batch comprises matrix resins, nano-silicate, coated red phosphorous agents, antistatic agents, polysiloxane silicone surface surfactants and boride charring agents. The weight percentages of the components are as follows: 5 percent to 20 percent of matrix resins, 3 percent to 5 percent of nano-silicate, 20 percent to 50 percent of coated red phosphorous agents, 10 percent to 20 percent of antistatic agents, 1 percent to 2 percent of polysiloxane silicone surface surfactants, and 10 percent to 15 percent of boride charring agents. The polyolefin is used as the matrix resins, and after a plurality of repeated tests and study the component percentages and technique of the flammable antistatic polyolefin master batch are reasonably determined, therefore the production of the master batch with three efficacies, namely, natural color, flammable and antistatic properties is realized; the problem of single color (black) of the flammable antistatic polyolefin master batch series can be solved and colorful plastic products can be prepared to enrich the environmental senses.

Description

technical field [0001] The invention relates to a natural flame-retardant and antistatic polyolefin masterbatch, which belongs to the technical field of preparation of color masterbatches for modification of engineering plastics. Background technique [0002] Polyethylene is the first of the five general-purpose plastics, and is widely used in various inlet and outlet pipes and various packaging materials. However, the current flame retardant and antistatic polyolefin masterbatches are all black in color. There is no report of natural masterbatch. Contents of the invention [0003] The purpose of the present invention is to provide a natural color flame retardant and antistatic polyolefin masterbatch with reasonable formula design, excellent performance and wide application range. [0004] The invention is a flame retardant and antistatic polyolefin masterbatch of natural color, which is characterized in that it includes matrix resin, nano silicate, coated red phosphorus...
