Abstract
The invention belongs to the field of melamine products and particularly relates to melamine tableware and a preparation method thereof. The melamine tableware is prepared from raw materials in percentage by weight as follows: 5%-15% of sodium citrate, 1%-3% of titanium dioxide, 40%-50% of amino molding particles, 10%-15% of wood fibers, 8%-13% of zinc stearate, 0.02%-0.2% of food coloring, 0.04%-0.1% of a curing agent and 15%-25% of plant fibers. The preparation method comprises preparation steps as follows: amino molding plastic powder is prepared, and a finished product is prepared. Steam heating is performed on a material in a kneading machine in the preparation process of the amino molding plastic powder, and water in the material is volatilized rapidly and fully. The plant fiber component is added, so that the strength, the heat resistance and the compactness of the product are more excellent; steam heating is performed on the material, the production efficiency is improved, and the product quality is enhanced.
Description
Technical field
The invention belongs to melamine arts, be specifically related to a kind of melamine dishware and preparation method thereof.
Background technology
Food tripolycyanamide products formed is the one of plastic containers, is commonly called melamine.The most universal being used by family, school, restaurant, fast-food restaurant, snack bar of melamine dishware, especially because its not easily broken feature, making a lot of family be used as Child tableware, due to popularity and the convenient and practical property of application, melamine product is more and more approved by people.Tradition melamine product produces owing to mediating Shortcomings in dispensing and material, there is the shortcomings such as resistance to elevated temperatures is poor, weatherability is poor, intensity is low, production efficiency is low, can produce the harmful substances such as formaldehyde, affect health under high temperature or microwave radiation.
Summary of the invention
The technical problem to be solved is to overcome above-mentioned deficiency, it is provided that a kind of melamine dishware and preparation method thereof, and this invention can not only improve production efficiency, and can increase the intensity of product, thermostability, improves material molecular weight, strengthens product quality.
Technical scheme:
A kind of melamine dishware, it is made up of the raw material of following percentage by weight: sodium citrate 5%-15%, titanium dioxide 1%-3%, amino film plastics granule 40%-50%, wood fibre 10%-15%, zinc stearate 8%-13%, food coloring 0.02-0.2%, firming agent 0.04-0.1%, Plant fiber 15-25%.
Above-mentioned melamine dishware preparation method, comprises the following steps:
(1) amino film plastics powder is made.Add water heating, mixing by zinc stearate, sodium citrate, then adds kneader with amino film plastics granule, titanium dioxide, wood fibre；By the blade worked in coordination in kneader, rotate, the material prepared is sufficiently mixed stirring；Amino film plastics powder is ground to obtain again through dry materials and crushing ball；
(2) make finished product: add in the magazine that cycle machine is supporting by amino film plastics powder together with zinc stearate, food coloring, firming agent, Plant fiber, warehouse-in can be packed through overcuring, compressing and edging.
In above-mentioned preparation method step (1), material whipping process in kneader can also use steam heater that material is carried out steam heating simultaneously, makes the moisture in material the most fully volatilize.
In above-mentioned preparation method step (1), blade can be forward, reverse or positive and negative rotation.
The present invention compared with prior art has the advantages that the present invention adds Plant fiber on material proportion, make the close property of the intensity of product, weatherability, thermostability, matter, scratch-proofness is more superior than common melamine product performance, avoid the generation of formaldehyde simultaneously, reduce the hazardness to human body to the full extent.The blade and the steam heater that utilize positive and negative rotation in material kneading process make moisture evaporation thorough, shorten the production time, improve work efficiency, improve material molecular weight, enhance product quality.
Detailed description of the invention:
