Environment-friendly adding type polyethylene flame-retardant masterbatch and preparation method thereof

Abstract

The invention discloses an environment-friendly adding type polyethylene flame-retardant masterbatch. The masterbatch comprises the following raw materials by mass: 10 parts of carrier resin, 15 parts of chlorinated polyethylene, 28 parts of decabromodiphenylethane, 10 parts of antimony trioxide, 3-10 parts of TBC (tri-N-butyl citrate) flame retardant, 12 parts of flame retardant synergist, 5-15 parts of MCA (melamine cyanurate) flame retardant, 8 parts of lubricating agent and 1 part of antioxidant. The polyethylene flame-retardant masterbatch is environment-friendly, non-toxic, clean and sanitary. The flame retardant efficiency is obvious; the processing performance is excellent; when the masterbatch is used for producing polyethylene products, the addition is low, so that the production cost for the polyethylene material can be greatly reduced; the polyethylene flame-retardant masterbatch is suitable for development of enterprises.

Description

Technical field [0001] The present invention relates to the field of polymer materials, in particular to an environmentally-friendly flame-retardant polyethylene masterbatch. The invention also relates to a preparation method of the environmentally-friendly added polyethylene flame-retardant masterbatch. Background technique [0002] Polyethylene (PE) is widely used in the fields of chemical industry, agriculture, construction and packaging due to its excellent performance, but its flammability is poor and the product has fire hazards. Therefore, it is necessary to modify its flame retardancy. In order to improve the flame retardancy of polyethylene materials, people usually add flame retardants to the raw materials. However, most of the flame retardants are powders. The dust is flying during processing and the operating environment is extremely poor, which seriously affects the health of processing personnel. The volume difference between the body and the resin substrate is larg...

AI Technical Summary

Problems solved by technology

[0002] Due to its excellent performance, polyethylene (PE) is widely used in chemical industry, agriculture, construction, packaging and other fields, but its flammability is poor, and the product has fire hazards, so it is necessary to modify its flame retardancy

In order to improve the flame retardancy of polyethylene materials, people usually add flame retardants to the raw materials for production. However, most of the flame retardants are powders. The volume difference between the body and the resin substrate is large, the density difference is huge, and the raw materials are difficult to mix evenly

In addition, extruders and injection molding machines have limited mixing of materials along the axial center and equipment vibration, which makes the powder easily sink and cause separation from the resin substrate, resulting in segregation

In addition, the powder is easy to agglomerate, which also makes the feeding inaccurate, resulting in component fluctuations, unstable material properties, and it is difficult to achieve the expected flame retardant effect.

In the prior art, the problem of poor operating environment is solved by preparing flame-retardant masterbatches, but the flame-retardant masterbatches in the prior art have the disadvantages of poor product dispersibility, difficult processing, toxicity, poor flame-retardant performance or high price.
