Abstract
The invention discloses a method for producing a wood plastic material by using wastes, which belongs to the field of living waste garbage resource recycling. The method is characterized by comprising the following steps: 1) crushing diaper waste into solid grains or powder, wherein the granularity of the solid grains or the powder is 10-250 meshes, crushing polyvinyl chloride, polyethylene or polypropylene recycled from the waste into resin powder, wherein the granularity of the resin powder is 100-150 meshes, and crushing straw into 100-200 meshes powder; 2) uniformly mixing 100 parts by weight of the diaper waste grains or powder, 20-30 parts by weight of the resin powder, 20-30 parts by weight of the straw powder and 1-10 parts by weight of auxiliary agent, wherein the mixing temperature is 100-110 DEG C; 3) pelleting; 4) forming so as to obtain the wood plastic plate material. By adopting the method, a great deal of used diapers can be rapidly and efficiently treated, and moreover modes such as combustion and burying which can generate harm to the environment, are not used in the treatment process, so that the method is environment-friendly, and moreover the used diapers are turned into wealth, and the requirement of construction of a great amount of municipal facilities, roads and viaducts is met.
Description
technical field [0001] The invention relates to a method for producing wood-plastic materials by using waste, and belongs to the field of resource recycling of domestic waste and old waste. Background technique [0002] Diapers, also known as paper diapers, are actually a product mainly made of water-absorbing polymer materials, with infants as the main consumer group. Diapers can absorb 40-60 times their own weight in normal saline, and 50-100 times their own weight in purified water. Therefore, children don't have to worry about wet pants when they pee, so they are commonly known as diapers. The water-absorbent polymer can absorb a large amount of water in an instant, thus avoiding the frequent change of pants caused by the baby's accidental urination, and even the problem of cold and fever of infants caused by the inability to change the pants in time. [0003] With the development of my country's polymer industry and the improvement of people's living standards in rece...
