Flame-proof antistatic master material and production method thereof

Abstract

The invention relates to a fire retarding antistatic masterbatch, comprising the following weight proportions of ingredients: 20 percent to 80 percent of carrier, 4 percent to 20 percent of fire retardant, 15 percent to 50 percent of antistatic agent and 3 percent to 20 percent of dispersant. The ingredients are prepared into the fire retarding antistatic master batch by pressurizing and kneadingor through a preparation method of double screw extrusion. The preparation method is characterized in that: 1. a convenient post processing of master batch and a good operation environment are available; 2. the dispersivity of the fire retardant and the antistatic agent are improved with good fire retardance and antistatic property of the products; 3. the product has permanent fire retardance andantistatic property; 4. the compound antistatic agent has certain synergy and low seepage threshold value; and 5. the adding quantity of the retarding agent is small, with little hazard smoke. The fire retarding antistatic masterbatch is prepared by pressurizing and kneading or by double screw granulation, and the products produced from the masterbatch has the advantages of permanent high conductivity, excellent retardance, little burning smoke, and comparatively low cost.

Description

technical field [0001] The invention relates to a functional masterbatch for plastic processing, in particular to a flame-retardant and antistatic masterbatch and a preparation method thereof. Background technique [0002] In the known technology, a synthetic resin is used as a carrier, and a variety of plastic functional additives are added, such as toughening, antistatic, coloring, flame retardant, matting and other additives, to prepare a functional masterbatch. Plastic modification by functional masterbatch method has the advantages of convenient use, clean environment, good fineness dispersion and stable quality. In terms of flame retardant modification, it is mainly achieved by adding flame retardants. For example, the commonly used combination of bromine and antimony is a cost-effective one, but it has the following disadvantages: First, the addition ratio is large, which affects material performance and cost; There are many toxic fumes when burning, which affects it...

Problems solved by technology

In terms of flame retardant modification, it is mainly achieved by adding flame retardants. For example, the commonly used combination of bromine and antimony is a cost-effective one, but it has the following disadvantages: First, the addition ratio is large, which affects material performance and cost; There are many toxic fumes when burning, so it affects its application range to a certain extent

In terms of antistatic, the method of adding antistatic agent is often used. There are non-permanent and permanent antistatic agents. The non-permanent type cannot be permanently antistatic due to migration, and the surface resistance of its products can only reach 10. 8 Ω
