Abstract

The invention belongs to the field of processing of daily necessities and in particular relates to a method for manufacturing a plastic elastomer injection moulded chopping board. The method comprises the following steps of: (1) moulding a plate material; (2) gluing the part coated with the plastic elastomer, wherein the glue is prepared by adding GPPS plastic into a solvent; the solvent is prepared by mixing butanone, methyl benzene butanone and dimethylbenzene according to the volume ratio of the butanone to the methyl benzene butanone to the dimethylbenzene of 3-5:2-4:2-4; and the GPPS plastic content is 5 to 10 weight percent; (3) performing injection moulding on the glued part, wherein a thermoplastic elastomer is adopted in the injection moulding process; and (4) inspecting the products and putting the qualified products into a storage. The invention also provides a bamboo-plastic or wood-plastic integrated chopping board. By the manufacturing method and the integrated chopping board, the anti-skidding problem of bamboo chopping boards is solved; the problem that wood chopping boards are easy to damage when washed repeatedly is solved; and the bamboo or wood and plastic elastomer can change colors randomly, so that attractive appearance and fashion sense of the bamboo chopping boards or the wood chopping boards are enhanced, and the development tendency of kitchen wares is met.

Description

technical field [0001] The invention belongs to the field of daily necessities processing, and in particular relates to a manufacturing method of a cutting board with plastic elastic body for edge wrapping or corner wrapping treatment and a bamboo-plastic or wood-plastic integrated cutting board. Background technique [0002] The chopping board is a cutting board, which is one of the necessities of daily life. Cutting boards are generally made of wood. Because wooden cutting boards have seams or moth-eaten holes, they are easy to breed germs, so they should be washed frequently or poured with boiling water to keep the cutting board clean and hygienic. Wooden blocks are the main cutting boards, because they are easy to wear and tear, and most of them are casted with plastics recently. However, plastic cutting boards are easily deformed due to thermal expansion and contraction, and the cutting boards are easy to slide on the desktop, which is not safe. Currently, bamboo cutti...
