Abstract

The invention discloses a preparation method of a composite plant fiber imitation porcelain bottle. The steps include: step 1, selecting raw materials, and the raw materials include: 80-100 parts of composite fiber powder, 10-30 parts of food-grade calcium carbonate superfine powder, 2- 8 parts of starch, 1-5 parts of rosin resin, 1-5 parts of carboxymethyl chitosan and 1-3 parts of silane coupling agent; Step 2, take each raw material and mix well, preheat at 70-90 ℃ for 1 ‑5min, and then press molding for 0.5‑5min under the conditions of 140‑170℃ and 30‑40MPa, that is, it is obtained. The invention makes full use of the advantages of plant fiber materials, adds food-grade calcium carbonate ultrafine powder as filler, and cooperates with the use of other additives to improve the mechanical properties of the material, improve the impact strength, and effectively prevent moisture , The adhesion of oil on the surface of the material and the penetration of the fiber wall cavity make the obtained imitation porcelain bottle high in strength, not easy to crack, resistant to falling, high surface gloss, and outstanding in water and oil resistance; the raw materials used are widely sourced, low in cost, and environmentally friendly , non-toxic.

Description

technical field [0001] The invention relates to the technical field of imitation porcelain materials, in particular to a preparation method of a composite plant fiber imitation porcelain bottle. Background technique [0002] Plant fibers are derived from crop straws and fast-regenerating plants. They are inexhaustible renewable resources in nature. They have the advantages of high strength, natural and simple surface texture, bright colors and novel textures, and are suitable for multiple production. , Repeatedly used items can replace some plastic, glass, pottery, porcelain and other products, such as vases, perfume bottles, wine bottles, etc. that are common in life. [0003] However, in the pulping process of plant fibers, many micropores will be formed on the surface of the cell wall, resulting in poor mechanical properties of the fiber material, low impact strength, and excessive surface wettability, showing hydrophilicity and poor water resistance. For this reason, wh...
