Straw plant fiber synthetic resin and preparation technology thereof

Abstract

The invention relates to the field of chemical materials, in particular to a straw plant fiber synthetic resin and a preparation technology thereof. The straw plant fiber synthetic resin is prepared from straw powder, rice bran wax, cellulose, aliphatic polycarbonate, corn starch, sorbitol, gum Arabic powder, superfine aluminum silicate and polylactic acid fiber. The preparation technology comprises the following steps that 1, fine particle straw powder is prepared; 2, a preliminary mixing material is prepared; 3, straw fiber powder is prepared; 4, a mixed addition material is prepared; 5, after the mixed addition material and polylactic acid fiber are stirred to be uniform, and blending extrusion and injection molding are performed to obtain straw plant fiber synthetic resin. In order to avoid waste of resources such as crop waste, the resources are sufficiently utilized, and environmental pollution is lowered; the production cost is low, the application range is quite wide, the advantage of rural resources can be brought into play, and effective methods and ways are provided for reasonably utilizing waste crops.

Description

technical field

[0001] The invention relates to the field of chemical materials, in particular to a straw plant fiber synthetic resin and a preparation process thereof. Background technique

[0002] As a large agricultural country, with the continuous harvest of agriculture, the output of crop straws and other wastes has also increased significantly, of which the output of bare straws is about 650 million t / year. Except for the development and utilization of feed and fertilizer, most of them are burned, which not only wastes resources, but also seriously endangers the natural ecological environment. Therefore, the comprehensive utilization of abandoned crops is of great significance. While human beings create modern civilization, it also brings negative impacts - white pollution. Disposable tableware, disposable plastic products, and agricultural mulch are difficult to recycle, and their treatment methods are mainly incineration and landfill. Incineration will produce a la...
