Embodiment 1

[0018] Put 75 kilograms of bamboo powder raw materials after sieving out impurities into the drier, and dry for 20 minutes at 120 degrees. Then the bamboo powder raw material is put into pulverizer, pulverizes and obtains 20 order bamboo powders. Add 8 kilograms of polyvinyl acetate adhesives again, put 17 kilograms of pulp into the mixer, and add water as diluent, stir to viscous state. Then, put the mixed material into a mold, press at 90-110 degrees at 0.1-0.5MPa to form a disposable comb for hotels. Natural cooling, spraying polyamide epoxy resin coating, sending it into the dryer, drying at 80 degrees for 30 minutes, cooling, inspection, disinfection, and packaging the finished product.

Embodiment 2

[0020] Put 80 kg of walnut shell powder raw material after sifting out impurities into a drier, dry at 100 degrees for 30 minutes, until the water content is below 2%, then put the walnut shell powder raw material into a grinder, and grind to obtain 50 mesh Walnut shell powder. Then add 8 kg of polyurethane adhesive and 12 kg of paper pulp, put the above raw materials into the agitator, and stir to a viscous state. Then, put the mixed material into the mold, pre-press molding at 80-100 degrees, 0.5-1.0Mpa pressure, leave the mold for 4 hours, and further solidify. Spray pervinyl chloride paint, send it into the dryer, and dry it at 60 degrees for 15 minutes. Cool, inspect, sterilize, and pack the finished product.

Embodiment 3

[0022] Put 40 kilograms of walnut shell powder raw materials and 30 kilograms of bamboo powder raw materials after sifting out impurities into a drier, and dry them for 30 minutes at 150 degrees until the water content is below 2% for later use; The acrylamide prepolymer is polycondensed, and then crosslinked and modified with diisocyanate to obtain 10 kg of modified starch adhesive, and then the modified starch adhesive is mixed with bamboo powder, walnut shell powder, and 20 kg of paper pulp and put into the mixer. Stir until thickened. Then, put the mixture into a mold, heat-press at 120 degrees under a pressure of 0.1-0.2Mpa for 2.5 minutes, and cool naturally. Spray polyamide epoxy resin paint, send it into the dryer, and dry it for 15 minutes at 60 degrees. Cool, inspect, sterilize, and pack the finished product.

Abstract

The present invention is process of making small hard handicraft with bamboo powder and / or walnut shell powder as material. The making process includes the following steps: sieving and depurating 10-65 mesh bamboo powder and / or walnut shell powder in 70-89 weight portions, drying and sterilizing at 80-150 deg.C, and crushing to 20-80 mesh material powder; adding environment friendly adhesive in 1-10 weight portions and paper pulp in 10-20 weight portions as well as certain amount of diluent; pressing in mold, demolding, painting waterproof protecting layer and drying. The small hard handicraft has low material cost, reasonable technological process, high quality and other advantages.

Description

technical field [0001] The present invention relates to a kind of preparation method of the small hard handicraft that uses bamboo powder and / or walnut shell powder as raw material, especially uses bamboo powder and / or walnut shell powder as raw material to make disposable comb, small hard handicraft daily necessities Preparation. Background technique [0002] Disposable combs are widely used in hotels and hotels. Cheap hard small handicrafts are also used in a large amount in daily life. At present, the raw materials selected for such products are mainly wood or plastic, which are produced by traditional methods such as carving, compression molding, and casting. Using wood as the main raw material needs to occupy limited resources, which is contrary to the purpose of establishing a conservation-oriented society in our country. Using plastic as raw material requires consumption of non-renewable resource petroleum, and its products have the defects of being non-recyclable ...
