Problems solved by technology

There are two disadvantages in this method: one: the resin used must go through the twin-screw before producing the product, which not only wastes electric energy, but also causes damage to the mechanical properties of the resin.
Although there are no existing patents in the form of similar masterbatches, such as: 200410067507.5, 92112913.0, they have great limitations and are only suitable for products made of one material, which is not universal and has poor performance

Abstract

The invention discloses strengthening-toughening type antistatic antiflaming master batches and a preparation method and application. The antistatic antiflaming master batches mainly comprise the following components of: a fire retardant, an antistatic agent, a processing aid and a carrier resin. The preparation method comprises the steps of: preparing the components in a formula ratio to obtain a mixture; plasticizing and mixing the mixture by using an internal mixer or a kneading machine first and then pelletizing by using a single screw extrusion machine to obtain the master batches; and or uniformly mixing the components by using a high mixing machine and then pelletizing the mixture by using a reciprocating type single screw extrusion machine to obtain the master batches. The antistatic antiflaming master batches not only have the antistatic and antiflaming function but also have the function of strengthening and toughening. The master batches are mainly used for plastic products, coal mine underground plastic pipes and top meshes which have high requirements on antistatic and antiflaming performance and strengthening and toughening performance, and can be used for gas transport pipelines and various plastic products of the electric appliances.

Description

Technical field: [0001] The invention relates to plastic antistatic and flame retardant materials, in particular to plastic products with high requirements for both antistatic and flame retardant properties. Such as: coal mine underground plastic products, flammable and explosive gas pipelines and plastic electrical products and other fields. Background technique: [0002] Plastic is a non-conductive and flammable polymer material. Many application fields, such as: electrical components, plastic pipes for underground coal mines, plate network products, plastic pipes or plastic containers for gas, natural gas and other flammable gas transmission, plastic electrical products, in order to avoid fire, both flame retardancy and Antistatic. At present, the production of this type of plastic products generally adopts the form of special materials. Such as: as described in patents 200610043497.0, 200610040792.0, 02135418.6, 200410036589.7: that is, antistatic components and flame...
