Bamboo, paper-making solid waste-based panels containing fibers and plastics and their manufacturing process

Abstract

The invention relates to an artificial board composed of bamboo and fibers-and-plastic containing papermaking solid waste and a manufacturing process of the artificial board. The artificial board and the manufacturing process are characterized in that the bamboo and the fibers-and-plastic containing papermaking solid waste are subjected to hot-press gluing formation, the weight ratio of the bamboo to the fibers-and-plastic containing solid waste is 1:(0.5-1), and resin accounting for 10%-20% of the total weight is added. The board is formed through raw material selection, proportioning, drying, mixing, addition of the bonding resin, blank making, hot pressing, cold-pressing sizing, storage through standing, and cutting. Due to the fact that the resourceful bamboo and the fibers-and-plastic containing solid waste generated in papermaking industry are adopted as the raw materials, the waste completely replaces original raw materials to serve as the raw materials to produce building boards without additives like formaldehyde, the problem of pollution caused by the papermaking solid waste can be effectively solved, native wood and plastic are saved, and the artificial board and the manufacturing process have great practical significance on saving of natural resources and protection of the ecological environment.

Description

Technical field [0001] The invention relates to the field of man-made board manufacturing and processing, in particular to a bamboo, fiber and plastic-containing paper-making waste man-made board and a manufacturing process thereof. Background technique [0002] During the "Eleventh Five-Year Plan" period, mainland China produced a total of 525.85 million cubic meters of wood-based panels, of which plywood was 21.22 million cubic meters, fiberboard was 15.946 million cubic meters, particleboard was 55.1 million cubic meters, and other wood-based panels were 97.07 million cubic meters. In 2010, China's wood-based panel output was 15.361 million cubic meters, a record high. Among them, plywood was 71.4 million cubic meters, a year-on-year increase of 60.4%; fiberboard was 43.55 million cubic meters, a year-on-year increase of 24.8%; particleboard was 12.64 million cubic meters, a year-on-year decrease of 11.7%; other man-made boards were 26.02 million cubic meters (blockboard accou...

Problems solved by technology

Although the incineration method utilizes the heat energy of these papermaking solid wastes, it is a resource recovery method, but in the process of incineration, various harmful gases will also be released, which will have a certain impact on the environment. At the same time, the ashes of these wastes should be properly disposed of It also needs to invest a certain amount of human and financial resources, and its comprehensive effect is not ideal compared with recycling these solid wastes

The use of landfill will not only occupy a large amount of valuable land resources, but also have potential hazards of secondary pollution to marine water quality, soil and groundwater.
