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 rubber crop straw medium density fiberboard, raw materials include crop straw fiber, adhesive, waterproof and lubricant, flame retardant The adhesive is natural gum, including peach gum, rosin gum, starch glue, locust bean gum, Arabic gum, pectin, copy glue adhesive and other plant glue, and bone glue, hide glue, gelatin, fish bladder glue, protein glue , shellac and other animal glues, you can use one kind, or you can use multiple kinds at the same time

Embodiment Construction

[0022] The crop straw medium density fiberboard using natural rubber of the present invention mainly includes crop straw fiber, adhesive, waterproof and lubricant, and flame retardant. Generally, natural gums used as adhesives include peach gum, rosin gum, starch glue, locust bean gum, Arabic gum, pectin, glue adhesive and other plant glues, and bone glue, hide glue, gelatin, isinglass, Protein glue, shellac and other animal glue can use one kind of natural glue in one formula, and can also use multiple kinds of natural glue at the same time. Using this method, according to the different properties of different natural glue, it can be combined into suitable for different Performance MDF natural rubber formulation. When the supply of some natural rubber is tight, using this method, several kinds of natural rubber with sufficient supply can also be used to form a natural rubber formula with qualified performance. Natural rubber has a wide range of uses and is used in food, medi...

Abstract

The crop straw medium density fiberboard using natural rubber, the raw materials include crop straw fiber, adhesive, waterproof and lubricant, flame retardant, and the adhesive is natural rubber, including vegetable glue and animal glue. Water repellants and lubricants are natural waxes, stearic acid or stearate salts. Flame retardants are non-toxic and harmless flame retardants. The proportion of various raw materials by weight is: crop straw fiber 75% to 93%, binder 1% to 8% (dry), waterproof and lubricant 0.5% to 8%, flame retardant 5.5% to 23.5% . Various raw materials are mixed, sizing, paving, pre-pressing, hot-pressing, and trimming to make finished products, and microwaves are used for auxiliary heating in the hot-pressing stage. The crop straw medium density fiberboard made of natural rubber of the present invention can be completely degraded under natural conditions after being discarded and damaged, and will not cause any irreversible damage to the environment, so that the production and use of crop straw medium density fiberboard can be realized. Complete sustainability and recyclability, with significant practical and historical 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 ...
