Problems solved by technology

In the prior art, in order to improve the antistatic, weather-resistant function and processing performance of polyester products, an appropriate amount of antistatic agents, weather-resistant agents, antioxidants and other auxiliary agents are usually added in the production process of polyester products to achieve polyester products. The above functions of ester products, but the existing problems are: there are many adding steps, it is difficult to ensure the uniformity of addition and product quality, and when mixed with powder additives, dust will be raised, which will pollute the surrounding environment and affect health, etc.

Abstract

The invention discloses a polyester anti-static and weather-resistant master batch and a preparation method thereof. The polyester anti-static and weather-resistant master batch comprises components by mass: 10%-20% of a carrier, 20%-30% of an anti-static agent, 10%-30% of a light stabilizer, 30%-40% of calcium carbonate, 3%-8% of a compatilizer, 2%-4% of a dispersant, 1%-2% of a coupling agent and 0.1%-1% of an antioxidant. The prepared master batch has the characteristics of high concentration, multifunction, low cost and convenient use. Anti-static and weather-resistant modifications can be completed by adding the master batch provided by the invention for one time according to a proportion in the production of a polyester product. The adding process is simple; the master batch is convenient for use and can increase mixing quality and performance indexes of the produced polyester product; production cost is reduced; efficiency is increased; pollutions of dust and auxiliary agents to the environment can be prevented; and clean production is facilitated.

Description

technical field [0001] The invention relates to a masterbatch, in particular to a polyester antistatic weatherproof masterbatch and a preparation method thereof. Background technique [0002] Polyesters include polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polyethylene naphthalate (PEN), among others. In the prior art, in order to improve the antistatic, weather-resistant function and processing performance of polyester products, an appropriate amount of antistatic agents, weather-resistant agents, antioxidants and other auxiliary agents are usually added in the production process of polyester products to achieve polyester products. The above functions of ester products, but the existing problems are: there are many adding steps, it is difficult to ensure the uniformity of addition and product quality, and when mixed with powder additives, dust will be raised, which will pollute the surrounding environment and affect health.
