Agronomic crop stalk medium density fiberboard using natural rubber and manufacturing method therefor

Abstract

The invention provides a crop straw medium density fiberboard by natural gum. Raw materials of the medium density fiberboard comprise crop straw fiber, a bonding agent, a waterproof and lubricating agent and a flame retardant, wherein the bonding agent is natural gum and comprises plant gum and animal gum; the waterproof and lubricating agent is natural wax, stearic acid or stearate; and the flame retardant is non-toxic and harmless flame retardant. The mixture ratio for all the raw materials by weight percent is: 75 to 93 percent of the crop straw fiber, 1 to 8 percent of the bonding agent (dried), 0.5 to 8 percent of the waterproof and lubricating agent, and 5.5 to 23.5 percent of the flame retardant. All the raw materials are produced into a finished product through mixing, sizing, spreading, prepressing, hot pressing and edge cutting; and microwave is used for auxiliary heating in the hot pressing phase. The crop straw medium density fiberboard by the natural gum can realize complete degradation under natural condition after the medium density fiberboard is abandoned or destroyed without any nonreversible destruction to the environment, so the production and application of the crop straw medium density fiberboard realize complete sustainability and recyclability, and have significant realistic and historic significance.

Description

technical field [0001] The invention relates to a crop straw medium density fiberboard, in particular to a crop straw medium density fiberboard using natural rubber. Background technique [0002] Due to the dwindling of forest resources, as well as the damage to the environment and the waste of resources caused by the traditional means of burning crop straws in the agricultural field, people are increasingly using crop straws as raw materials instead of wood to make construction and decorative panels, Paper and various fiber products. Crop straw fiberboard is a common building and decorative board made of crop straw instead of wood. However, due to the problems of raw material performance, raw material selection and raw material supply, fiberboards made of crop straw are generally still used in traditional wood-based panels. Chemical synthetic adhesives such as urea-formaldehyde, phenolic formaldehyde, melamine and isocyanate are used as adhesives, which not only consume a ...

Problems solved by technology

[0003] In order to solve the problem that all or part of the existing crop straw fiberboard production uses chemical synthetic glue as an adhesive, consumes non-renewable resources, pollutes the environment, and makes the crop straw wood-based panel industry unsustainable and recyclable. The present invention A crop straw medium density fiberboard using natural rubber and its manufacturing method are proposed, the method adopted is: using natural rubb
