Problems solved by technology

[0004] The emergence of plastic masterbatches solves technical problems such as large pollution, uneven dispersion, and difficult processing, and reduces costs. In the cold season, many plastic products will adsorb some tiny particles on the surface, so it is necessary to develop an anti-static plastic masterbatch to improve the above situation

Embodiment 1

[0023] A flame-retardant plastic masterbatch, which is composed of the following raw materials in parts by weight: 15 parts of carrier resin (polyethylene), 75 parts of functional filler, 0.5 parts of toughening agent, 5 parts of antistatic agent, coupling agent (titanate 1 part of coupling agent), 1.5 parts of dispersant (zinc stearate), 2 parts of lubricant (glyceryl stearate), and the antistatic agent is sodium alkylsulfonate. The functional filler is made by mixing modified nano-calcium carbonate and graphene oxide in a mass ratio of 9:1. The particle diameter of the modified nano calcium carbonate is 40-80nm, and the particle diameter of the graphene oxide is 10-30nm.

[0024] The preparation process of modified nano-calcium carbonate: 1) Saponification reaction; add fatty acid with a concentration of 10% into the saponification tank, then add sodium hydroxide accounting for 12% of the fatty acid mass, and carry out saponification reaction at 80°C for 15 minutes to obtain...

Abstract

The invention belongs to the technical field of plastics, and particularly discloses an antistatic plastic master batch which comprises 10-40 parts of carrier resin, 50-80 parts of functional filler, 0.5-1 part of flexibilizer, 1-5 parts of antistatic agent, 0.5-1.5 parts of coupling agent, 1-2 parts of dispersing agent and 2-5 parts of lubricant, and the antistatic agent is anionic antistatic agent. The melamine and the derivative release nitrogen during high-temperature combustion and are non-toxic and halogen-free antistatic agents, and due to the action of the coupling agent and the dispersing agent, the antistatic agent is easier to be uniformly dispersed in the carrier resin and plays a role of the antistatic agent, and meanwhile, the mechanical property of the master batch is not reduced.

Description

technical field [0001] The invention belongs to the technical field of plastics, in particular to an antistatic plastic master batch. Background technique [0002] Plastic is an important organic polymer synthetic material, which can be divided into general-purpose plastics, engineering plastics, special engineering plastics, etc. according to application fields; it can be divided into thermoplastics and thermosetting plastics according to thermodynamic properties. Therefore, plastics are widely used in many fields such as agriculture, electronics, transportation, construction, packaging, national defense, and daily life. However, during the processing of plastics, there are problems such as large pollution, uneven dispersion, and difficult processing, and the processing cost is high, and the chemical properties of the materials cannot meet expectations. [0003] Nano-calcium carbonate plays the role of filling and reinforcement in plastics, which not only reduces the cost,...
