Embodiment 1

[0025] The application of polysilicon waste materials in the rubber modified masterbatch listed in this embodiment. The polysilicon waste materials are waste materials generated in the process of producing polysilicon. Its main component is silicon tetrachloride, which accounts for 99% of the total weight of the waste materials, and the balance is other Impurities.

[0026] The application of polycrystalline silicon waste in the rubber modified masterbatch listed in this embodiment includes mixing the polycrystalline silicon waste with activated rubber powder and matrix asphalt, and kneading in a kneader to obtain the rubber modified masterbatch.

[0027] The kneading temperature is 20-40°C.

[0028] The base asphalt is preheated to 160° C. before mixing, the base asphalt is first mixed with activated rubber powder, and the resulting mixture is then mixed with polysilicon waste.

Abstract

The invention relates to an application of a polysilicon waste material, and relates to an application of the polysilicon waste material in preparing rubber-modified masterbatch. The method comprises the steps that: the polysilicon waste material is mixed with activated rubber powder, and substrate asphalt; the mixture is kneaded in a kneader, such that the rubber-modified masterbatch is obtained. The application method of the polysilicon waste material causes no three-waste public nuisance, and is environment friendly. More importantly, the waste material of rubber and polysilicon industriesare turned into valuable matters. The prepared rubber-modified masterbatch is advantaged in low cost, good low-temperature resistance, and good oxidation-resistance.

Description

Technical field [0001] The invention relates to an application of polycrystalline silicon waste, in particular to a method for processing polycrystalline silicon waste. Background technique [0002] In recent years, my country’s demand for polysilicon has increased day by day, and a large amount of polysilicon waste has been produced during the production of polysilicon. Depending on the number of times of hydrogenation and recycling and other reaction conditions, the composition of polysilicon waste is different, but its main component is silicon tetrachloride, and it accounts for about 99% of the total weight of polysilicon waste, and the balance is other impurities. According to statistics, the production of 1 kilogram of polysilicon will produce 10-15 kilograms of silicon tetrachloride, and the by-product silicon tetrachloride produced by a 1,000-ton / year polysilicon plant will reach 10,000-15,000 tons a year. Simple water treatment and even discharge of silicon will put tre...
