Problems solved by technology

[0004] The main base material of the plant fiber products made by the above two patents is plant fiber, and the product contains a certain amount of starch components. And the molecular weight of starch fails to fully release the molecular chain conformational energy, a large amount of molecular stress remains, and the product is prone to warping

Abstract

The invention relates to a method for moisturizing and anti-warping of paraffin milk of a plant fiberboard. The method comprises the following steps: placing gum acacia powder in a dry container, uniformly grinding, then adding liquid paraffin, grinding to be mixed uniformly, then adding distilled water, and grinding uniformly to obtain the paraffin milk; placing the paraffin milk and a plant fiber material in a high-speed ball mill, mixing uniformly, obtaining a mixed material; placing the mixed material in a high-temperature mould pressing machine, pressing and molding, and finally demolding and cooling to room temperature to obtain the plant fiberboard, wherein the plant fiber material is rice husk fiber synthetic resin powder or plant fiber synthetic resin powder. According to the invention, the gum acacia powder and the liquid paraffin are mixed uniformly and dissolved in the distilled water to prepare a humectant, and are mixed with the plant fiber material uniformly to obtain a product by pressing and molding. The humectant can lock the easy-to-lose water and prevent a molecular chain from being deformed, the steps are simple, the design is reasonable, implementation is convenient, and the effect is good.

Description

technical field [0001] The invention relates to a production process of plant fibers, in particular to a method for moisturizing and preventing warping of plant fiber boards with paraffin emulsion. Background technique [0002] The plant fiber products made of rice husk fiber or plant fiber, whose raw materials are all derived from nature, have the characteristics of green and environmental protection. They can be degraded into organic fertilizers in nature and return to nature, so they have broad market prospects. . [0003] The applicant has consistently devoted himself to the development and research of plant fibers, made great progress, and applied for two patents on the research and development results. Patent 1: The patent authorization announcement number is CN102690524B, and the authorization announcement date is 2014.09.10. The patent name is a production process of rice husk fiber synthetic resin powder and rice husk fiber products. Patent 2: The authorized annou...
