Abstract
Description
Technical field
[0001] The invention relates to the field of polymer materials, and in particular to a polylactic acid toughened, heat-resistant composite material and a manufacturing method of its products. Background technique
[0002] Traditional melamine tableware, also known as melamine tableware, is made from amino molding compounds. It is made by reacting melamine and formaldehyde under certain conditions to form melamine-formaldehyde resin, and then adding auxiliary materials such as curing agent, cellulose and colorants. The material is molded and pressed into imitation tableware. Tableware products made of imitation porcelain tableware materials are strong, smooth in surface, resistant to high temperature and water impact, not fragile, and have the characteristics of ceramic texture. They have become one of the indispensable materials for tableware manufacturing, especially in restaurants, restaurants and student canteens. It is widely used and is a characteristic...
