Abstract

The invention relates to a polylactic acid bonding plate and a preparation method thereof. The polylactic acid bonding plate comprises a polylactic acid plate and a polylactic acid film; the polylactic film is processed and bonded to the surface of the polylactic acid plate. The preparation method of the polylactic acid bonding plate comprises the steps as follows: forming the polylactic acid plate and the polylactic film; leading the polylactic film to be bonded to at least one surface of the polylactic plate by the temperature, at which the polylactic film can be melted and softened. The polylactic acid bonding plate and the preparation method of the invention can improve the shortage that the existing plastic plate does not comply with the environmental protection requirement.

Description

technical field [0001] The invention relates to a polylactic acid laminated board and a manufacturing method thereof, in particular to a polylactic acid laminated board and a manufacturing method thereof that can replace traditional plastic boards and provide a more environmentally friendly choice. Background technique [0002] Due to the rapid development of the plastic industry, people have relied on the lightness and durability of plastic products for a long time, so plastic has gradually replaced other materials, but this has also created the waste habit of "use and throw away" and the source of pollution. [0003] Plastic products are made of petroleum raw materials, which are not easy to decompose and corrode. The landfill treatment of plastic waste will reduce the service life of the landfill site, cause soil and river pollution, and even cause the respiratory organs of aquatic animals to be blocked, resulting in secondary public hazards such as suffocation and death....
