Abstract

The invention relates to a composite material for kitchenware and especially relates to a melamine composite material for kitchenware. The melamine composite material for kitchenware solves the problem that melamine kitchenware prepared from the existing melamine raw material has formaldehyde content out of the limit and comprises: by weight, 23 to 30 parts of esterified corn starch, 0.8 to 2.6 parts of wood flour, 0.6 to 1.5 parts of a coupling agent, 1 to 1.5 parts of a plasticizer, 0.6 to 1.4 parts of a lubricant, and 63 to 74 parts of melamine powder, wherein the coupling agent is an aluminum-titanium composite coupling agent; the plasticizer is glyceryl monostearate; and the lubricant is stearic acid. The melamine composite material for kitchenware has the advantages that green, environmentally-friendly, cheap and free formaldehyde-reducing materials of esterified corn starch, wood flour and other auxiliary agents are used to prepare a melamine raw material which has low free formaldehyde concentration and is suitable for kitchenware and thus a manufacturing cost of melamine kitchenware is reduced. Melamine kitchenware prepared from the melamine composite material has a formaldehyde monomer migration rate far below the national standard and the novel European standard.

Description

technical field [0001] The invention relates to a composite material for kitchen utensils, in particular to a melamine composite material for kitchen utensils. Background technique [0002] Melamine-formaldehyde resin (melamine-formaldehyde resin), the polymer obtained by the polycondensation reaction of formaldehyde and melamine, also known as melamine-formaldehyde resin, melamine resin, English abbreviation MF, is colorless and transparent, stable in boiling water, and can even be used at 150 ℃, and has self-extinguishing, arc resistance and good mechanical properties. The raw material of melamine (imitation porcelain) tableware and kitchenware is melamine formaldehyde molding compound (commonly known as melamine powder). Melamine powder is made by mixing MF with α-cellulose and other additives, drying, ball milling and sieving . Although the reaction of formaldehyde and melamine polycondensation to obtain MF is an irreversible reaction, according to the characteristics ...
