Abstract

The invention discloses a straw reinforcement plate and a preparation process thereof. The plate is prepared from the following raw materials in parts by weight: 120-150 parts of straw, 20-30 parts ofa binder, 18-25 parts of urea-formaldehyde resin glue, 10-18 parts of a waterproofing agent, 8-15 parts of polypropylene plastic, 6-12 parts of carbon powder, 8-13 parts of titanium dioxide, 10-18 parts of cement powder, 8-12 parts of quartz sand, 10-16 parts of zinc laurate, 8-14 parts of sodium acrylate and 6-12 parts of a curing agent. The straw reinforcement plate is prepared from the rural straw as a main material by adding the binder, the urea-formaldehyde resin glue, the curing agent and the like; the prepared reinforcement plate has higher strength and can replace solid wood to be widely used in the fields of household decoration, furniture manufacturing, handicraft manufacturing and the like, and higher economic benefits are produced; the rural waste straw is fully used, the natural environment is protected, and huge manpower and material resources are saved for straw processing.

Description

technical field [0001] The invention belongs to the field of straw reprocessing, and in particular relates to a straw reinforced board and a preparation process thereof. Background technique [0002] The autumn harvest in rural areas will produce a large amount of waste straw, and the traditional straw treatment method is mostly incineration, which wastes resources and pollutes the environment. The fields of home decoration and furniture manufacturing require a large amount of panels. Continuous deforestation is not a way of green development, nor is it sustainable. If there is a good substitute for solid wood, it can protect the environment and generate huge economic benefits. Contents of the invention [0003] The purpose of the present invention is to solve the above problems, to provide a straw reinforced board, the raw material is mainly straw, by adding esters, glue, quartz sand, cement powder, etc., mixed and hot pressed by modern technology, the fiber produced Th...
