Embodiment 1

[0027] After fully mixing the raw materials in Table 1, hot press molding at a temperature of 145°C and a pressure of 200t to obtain a semi-finished product with a certain shape, and perform surface cleaning treatment on the semi-finished product: wash the surface of the semi-finished product with water, and dry the surface of the semi-finished product to be cleaned. Spray a layer of transparent protective film with a thickness of 0.04mm on the outer surface of the semi-finished product, and then bake it at 100°C for 30 minutes. The protective film is polyester resin containing 0.5% (weight) matting agent. The particle size of the bamboo fiber is 60 mesh, and the particle size of the starch is 2000 mesh. The polyester resin in the present invention is a non-toxic and harmless resin that meets food-grade safety. For the convenience of description, the following examples all take acrylic resin as an example.

Embodiment 2

[0031] After fully mixing the raw materials in Table 1, hot press molding at a temperature of 160°C and a pressure of 300t to obtain a semi-finished product with a certain shape. Clean the surface of the semi-finished product: clean the surface of the semi-finished product with alcohol, and dry the surface of the semi-finished product to be cleaned. , spray a layer of transparent protective film with a thickness of 0.06mm on the outer surface of the semi-finished product, and then bake it at 120°C for 50 minutes. The protective film is an acrylic resin containing 0.6% by weight of a matting agent. The particle size of the bamboo fiber is 80 mesh, and the particle size of the starch is 1500 mesh.

Embodiment 3

[0033] After fully mixing the raw materials in Table 1, hot press molding at a temperature of 150°C and a pressure of 250t to obtain a semi-finished product with a certain shape, and perform surface cleaning treatment on the semi-finished product: wash the surface of the semi-finished product with water, and dry the surface of the semi-finished product to be cleaned. Spray a layer of transparent protective film with a thickness of 0.06mm on the outer surface of the semi-finished product, and then bake it at 100°C for 30-50 minutes. Protective film is acrylic resin with 1% by weight matting agent. The particle size of the bamboo fiber is 60-80 mesh, and the particle size of the starch is 1800 mesh.

Abstract

The invention relates to tableware containing bamboo fibers and a making method thereof. The tableware containing bamboo fibers is made of bamboo fiber compositions through hot pressing molding. The making method comprises the following steps of: a, fully mixing the bamboo fiber compositions, and then molding at a temperature of 145-160 DEG C and under the pressure of 200-300t through hot pressing to obtain a semi-finished product of a certain shape; b, carrying out surface cleaning processing on the semi-finished product: cleaning the surface of the semi-finished product by water or alcohol;c, spraying one layer of transparent protecting film on the outer surface of the semi-finished product after the surface of the semi-finished product to be cleaned is dried; and d, baking at a temperature above 100 DEG C for 30-50 minutes. The tableware is made by carrying out proper proportioning on special materials, pressing and molding and then spraying one layer of transparent protecting film, so that the product reaches food stage safety, the service life is prolonged; meanwhile, the tableware has the property of being easily biologically degraded. According to the tableware, the defectthat bamboo fibers cannot be molded through solidification or the molded tableware containing the bamboo fibers cannot meet food stage requirements in the prior art is overcome.

Description

technical field [0001] The invention relates to a composite material, in particular to a tableware containing bamboo fiber and a preparation method thereof. Background technique [0002] Existing catering utensils adopt food-grade plastics, pottery, glass etc. to make mostly, also have to process with natural bamboo main body. With the increasing awareness of environmental protection, renewable natural plant fibers are widely used in the field of material technology. Bamboo fiber is a kind of cellulose fiber extracted from naturally growing bamboo. It is the fifth largest natural fiber after cotton, hemp, wool and silk. Bamboo fiber has the characteristics of good air permeability, instant water absorption, strong wear resistance and good dyeability, and at the same time has natural antibacterial, antibacterial, anti-mite, deodorant and anti-ultraviolet functions. The natural environment-friendly green fiber. Because the output of bamboo fiber is relatively large, and the...
