Problems solved by technology

However, the general melamine formaldehyde resin is not resistant to high temperature and cannot be placed in a disinfection cabinet for high temperature disinfection, otherwise it will cause scorching. In addition, the decomposition of the resin will produce free formaldehyde, which seriously endangers people's health.
Therefore, it should not be widely used in food containers and packaging materials
In addition, due to the lack of processing and molding technology, the current resin utensils have uneven quality, and the temperature resistance of the manufactured utensils is only about 80°C, and the strength is relatively small.
Therefore, although the general melamine formaldehyde resin is light, it also has the properties of oil resistance, alcohol resistance, and pollution resistance, but it generally cannot be used to make environmentally friendly and safe tableware or tableware.

Embodiment 1

[0017] A kind of manufacture method that combines the household utensil of bamboo fiber, comprises following manufacturing steps:

[0018] (1) Make bamboo fiber: grind and pulverize bamboo material, bamboo material comprises bamboo, bamboo leaf etc., grind and pulverize to obtain bamboo fiber powder;

[0019] (2) Take formaldehyde, melamine and water in a weight ratio of 1:1:2; heat the formaldehyde at 80-100°C for 25 minutes, add melamine, keep the temperature at 90°C, and polymerize to form melamine-formaldehyde resin. After the reaction is complete , put the melamine-formaldehyde resin obtained by the reaction into water at 100°C and boil for 70 minutes; then place the melamine-formaldehyde resin in a cold formaldehyde solution to soak and crystallize to form crystals of the melamine-formaldehyde resin, then rinse with clear water several times, and finally dry;

[0020] (3) get above-mentioned melamine formaldehyde resin crystal and bamboo fiber respectively by the weight ...

Embodiment 2

[0023] A kind of manufacture method that combines the household utensil of bamboo fiber, comprises following manufacturing steps:

[0024] (1) making bamboo fiber: bamboo material is ground and pulverized to form bamboo fiber powder;

Abstract

The invention relates to the making of the combined fiber furniture by making the bamboo fiber, with formaldehyde and melamine polymer formed into melamine formaldehyde resin, putting the resin into the 100deg.C water for 50-70min, cooling the resin for crystallization, flush and drying. It selects resin crystallization and bamboo fiber in 1:1 weight ratio, mixing the grinding, adding mold stripping agent and hardening agent, blending evenly for crushing and screening. hot pressure forming. It is safe, poisonously, light in weight, strong, heat, oil and alcohol resistant, and environment protective.

Description

technical field [0001] The invention relates to the field of novel hygienic and environment-friendly utensils, in particular to a method for making household utensils combined with bamboo fibers. Background technique [0002] Present household utensils, including utensils, tableware, decorative items, etc., are mainly made of ceramics, glass, metal, wood, plastics and other materials. Ceramic material is the main material for making tableware. It is stable in nature, heat-resistant, oil-resistant, alcohol-resistant, and pollution-resistant. It is an environmentally friendly and hygienic household utensil material. However, ceramics are brittle, easy to break, and heavy, so they cannot be made into a transparent product. Glass material is transparent and beautiful, but it is highly brittle, not resistant to high temperature, and poor in pollution resistance, so it is not suitable for use as tableware or tableware. Metal products have high strength, are not afraid of strong ...
