Problems solved by technology

However, due to the thinner thickness of the chopping board, the rigidity is poor and the cost is higher
Composite chopping boards, the most typical ones are bamboo-plastic composite chopping boards, which are laminated bamboo boards glued together, so that the water absorption of the chopping boards is reduced and the durability of the chopping boards is improved. Therefore, forest waste is unavoidable. In addition, the shape and color of this kind of chopping board are relatively single, and it is easy to age.

Abstract

The invention provides a method for preparing a bamboo plastic chopping board, which comprises the following steps of: grinding a scrap material obtained by processing a bamboo and wood material into bamboo powder and sieving the bamboo powder; after drying the bamboo powder for 8 to 24 hours at the temperature of between 80 and 120 DEG C, spraying 1 to 3 percent of titanate on the surface of thedried bamboo powder; spraying titanate in an amount which is 1 to 3 percent based on the mass of talcpowder on the surface of the talcpowder or calcium carbonate after drying the talcpowder or the calcium carbonate for 2 to 4 hours at the temperature of between 70 and 100 DEG C to form a packing material; adding a lubricant in an amount which is 1 to 3 percent based on the mass of matrix materials into the matrix materials to form a mixture, wherein the matrix materials are one or more of polypropylene, propyl ethylene and polystyrene; and after sufficiently mixing the bamboo powder, the packing material, the mixture and a mixture consisting of a coupling agent, an antioxidant and an antibacterial agent, transferring the mixture to an extruder to carry out extrusion granulation and finally carrying out injection molding on the obtained product in an injection molding machine. The bamboo plastic chopping board of the invention is made of the scrap material obtained by processing the bamboo and wood material so as to reduce the cost of the chopping board. Meanwhile, the chopping board prepared by the method of the invention is difficult to deform and has low hygroscopicity.

Description

【Technical field】 [0001] The invention relates to a method for preparing a cutting board, in particular to a method for preparing a bamboo-plastic cutting board. 【Background technique】 [0002] my country has very rich bamboo resources, and the bamboo forest area accounts for a quarter of the world's total. Bamboo products are widely used in daily life, however, the utilization rate of bamboo wood is low, generally only 40%, so more than 60% of bamboo wood becomes waste during processing, [Luo Xinxiang, Wen Ruiming, etc. Bamboo wood processing surplus A Review of Research on the Development and Utilization of Resources. Journal of Hunan City University, Volume 13, Issue 3, September 2004]. How to make full use of the waste materials of bamboo and wood has become the great attention of relevant enterprises. [0003] Chopping boards are mainly divided into solid wood cutting boards, plastic cutting boards and composite cutting boards on the market. Among them, solid wood cu...
