Problems solved by technology

However, in the actual processing process, the application of rice husk powder has many disadvantages
1. Rice husk powder is in the form of fine powder, which can easily cause dust to fly in the whole workshop and seriously affect the health of workers
2. During the molding process, the clamping pressure of the molding machine will cause the rice husk powder to overflow from the mold, resulting in waste of raw materials, and will greatly affect the quality and size of the finished product, reducing the qualified rate of the product
3. Due to the different performance and shape requirements of the product, it is necessary to make appropriate adjustments to the formula of the product. However, in the actual production process, it is difficult to accurately grasp the ratio of each raw material (especially rice husk powder is easy to lose), which is seriously unfavorable to the product. design

Abstract

The invention relates to a rice hull powder master batch which is mainly prepared from the following components in parts by weight: 1000 parts of rice hull powder, 8-12 parts of a siloxane coupling agent, 2-3 parts of ethanol solution, 110-130 parts of a thermoplastic resin, 45-55 parts of a plasticizer, 8-12 parts of an antioxidant and 18-21 parts of a lubricating agent, wherein a melting temperature of the thermoplastic resin is 120-180 DEG C. According to the master batch disclosed by the invention, the rice hull powder serves as a matrix, the surface of the rice hull powder is subjected tomodification treatment, the thermoplastic resin, the plasticizer, the antioxidant, the lubricating agent and the like are added into a high-speed mixer to be heated, mixed and stirred, and the mixture is subjected to extrusion granulation by a twin-screw extruder so as to obtain the rice hull powder master batch. The rice hull powder master batch disclosed by the invention has the characteristicsof being easy to process and capable of accurately controlling the material ratio, improving the product quality and reducing losses of raw materials, and the like.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a rice husk powder masterbatch and a preparation method thereof. Background technique [0002] In recent years, plant fibers have been widely used and processed into new environmentally friendly materials, which are used to replace plastics, glass, ceramics, wood and bamboo to make tableware, toys, furniture, decorative lamps and other products. Raw materials are cheap and inexhaustible, renewable and natural, and plant fibers come from rice husks, rice straw, wheat straw, corn stalks, cotton stalks, wood chips, bamboo chips and other agricultural wastes, the total amount of which far exceeds that of petroleum and coal. , the total amount of natural gas. [0003] The applicant has applied for several patents on using rice husk powder as a raw material to produce environmentally friendly materials. However, in the actual processing process, there are many disadvantages in the ap...
