Preparation method of ABS composite plastic product capable of reducing loss of plant extract

Abstract

The invention provides a preparation method of an ABS composite plastic product capable of reducing loss of a plant extract. The content of the plant extract in the ABS composite plastic product is 0.1-5%. When the plant extract and the ABS composite plastic product are prepared, the loss of the plant extract can be reduced. According to the invention, the plant extract is modified and then made into a functional master batch, so the influence of the addition of the plant extract on the mechanical properties of the ABS plastic product can be reduced under the condition of reducing the high-temperature loss of the plant extract. The ABS plastic product prepared by the invention has the plant extract content 0.1-5%, preferably 2.4-4.5%, impact strength of 97.5-97.8 KJ / m<2>, bending strengthof 66.6-66.8 MPa, tensile strength of 43.4-43.6 MPa, and the elongation at break of 9.8-10.1%.

Description

technical field [0001] The invention provides a method for preparing an ABS composite plastic product that reduces the loss of plant extracts, and belongs to the technical field of plastics. Background technique [0002] ABS resin has good mechanical properties and molding processing characteristics, and is widely used in household appliances, office equipment, daily appliances, packaging materials, automotive interiors and other fields. [0003] China has an industrial standard for antibacterial plastic products. The antibacterial standard is: Antibacterial plastics with an antibacterial rate of ≧90% can be used as antibacterial plastics. At present, the reports on antibacterial materials are concentrated on polypropylene materials, and the reports on ABS antibacterial materials are relatively low. Few, more no reports of adding plant extracts to ABS to prepare ABS plastic products containing plant extracts. [0004] Plant extracts have antibacterial effects and are natura...

Problems solved by technology

[0005] However, plant extracts have the disadvantage of not being resistant to high temperatures. When the applicant compounded plant extracts and ABS to prepare plastic products, they found that plant extracts were easily carbonized at high temperatures, resulting in loss and serious loss. Bacterial performance is affected, and product appearance is affected due to charring

[0006] And the addition of plant extracts will also reduce the mechanical properties of plastic products
