Abstract

The invention discloses high-strength impact-resistant melamine resin tableware and a preparation method thereof. The high-strength impact-resistant melamine resin tableware is prepared from the following raw materials in parts by weight: 60 to 75 parts of melamine-formaldehyde resin, 16 to 22 parts of ethylene-methyl methacrylate copolymer powder, 25 to 33 parts of an elastomer, 5 to 8 parts of cellulose, 1.5 to 2.5 parts of zinc peroxide, 3 to 5 parts of aluminum borate whiskers, 3 to 5 parts of nano silicon dioxide, 2.5 to 3.5 parts of zinc stearate, 1 to 2 parts of triethanolamine and 1.5 to 2 parts of methylmalonic acid. The high-strength impact-resistant melamine resin tableware is high in impact strength, high in tensile strength, excellent in mechanical property, resistant to impact (impact), not prone to damage and cracking and the like; the migration volume of free formaldehyde is low, and the maximum migration volume of lead and cadmium is also low and is lower than the migration volume of free formaldehyde and the maximum migration volume of lead and cadmium in a comparison file 1, so that the tableware is healthy, environment-friendly and non-toxic; and in addition, the thermal decomposition initial temperature reaches 145 DEG C or above, the thermal decomposition initial temperature is high, and the heat resistance is good.

Description

technical field [0001] The invention relates to the field of melamine resin tableware, in particular to a high-strength impact-resistant melamine resin tableware and a preparation method thereof. Background technique [0002] Melamine tableware, also known as melamine tableware, is a resin formed by the polymerization of melamine and formaldehyde, which is used to manufacture melamine bowls, plates, chopsticks and other food containers in food packaging materials. Melamine resin has the characteristics of odorless, tasteless, non-toxic, and bright color. The tableware made of it can be used safely for a long time in the range of 30-120 °C. This kind of tableware is widely used in the fast food industry, staff canteens and children's because of its smooth surface, light weight, beautiful appearance, low temperature resistance (can be directly placed in the refrigerator), steaming resistance (boiling water cooking), pollution resistance, and not easy to break. catering indust...
