Abstract
The invention provides a method for preparing a board by using oxidized starch adhesive and waste plant fiber. The method comprises the following steps of: dissolving urea into water, adding starch into the solution, mixing the solution uniformly with stirring, then dripping 30 to 50 percent sodium hydroxide solution into the solution to gelatinize the starch, and finally dripping sodium hypochlorite solution into the solution to obtain oxidized starch solution; and mixing the prepared oxidized starch solution and the waste plant fiber powder uniformly, then putting the mixture into a die, and performing normal pressure or pressure forming, die release and drying to obtain the plant fiber board. The raw material used in the method is the waste plant fiber, so the method has low cost and has energy-saving and environment-friendly effects, and the prepared plant fiber board has light weight, does not contain harmful substances such as formaldehyde and the like and can be widely applied in the fields of packing, furniture, decoration and the like.
Description
Technical field
The present invention relates to a kind of preparation of plates method, particularly relate to a kind of method with oxidized starch adhesive and discarded plant fiber production sheet material, the vegetable fiberboard of this method preparation has advantages such as energy-saving and environmental protection, cost are low, reusable edible, will be widely used in industries such as packing, furniture and decoration.
Background technology
Sheet material is the main raw that use in fields such as packing, furniture and decoration, and market demand is very big.Traditional sheet material generally is wooden or plasthetics.Wood-based planet does not pollute the environment, but wood consumption conference vegetation destruction too be unfavorable for environment protection, and its price is higher.Reach the low characteristics of cost soon though plastic sheet has moulding, but the waste after this sheet material uses can serious environment pollution.
Along with rapid economy development, the raising of people's living standard, the depleted vegetable fibre is rapid growth thereupon also.The discarded plant fiber mainly comprises waste wood material and waste paper two big classes.Waste wood material (comprising wood-base fibre and particle panel material) refers to from the harvesting of wood, as the waste wood material of the first time, the output of wood-processing industry for the second time; Industry depleted wood materials such as transportation, packing; The waste wood material that building, civil engineering work etc. are produced; Woodwork (door, window, furniture) that family updates or the like; Waste paper comprises all kinds of paper, cardboard and tr etc.Abroad, waste wood material and paper are called as following " the 4th forest ".How rationally to handle and utilize these depleted sponges, become a great problem of current society.
Summary of the invention
The purpose of this invention is to provide a kind of method with oxidized starch adhesive and discarded plant fiber production sheet material.
Technical scheme of the present invention is as follows: earlier urea is dissolved in the water, add starch again, mix under stirring, drip the sodium hydroxide solution that concentration is 30%-50% then, make starch pasting, drip the chlorine bleach liquor that available chlorine content is 0.177%-15.992% at last, promptly make Sumstar 190 solution; The Sumstar 190 solution and the discarded plant fiber dust that make are mixed, put into mould then, through normal pressure or extrusion forming, the demoulding and drying, can make vegetable fiberboard, wherein starch is 1 with Total Water, urea, sodium hydroxide, chlorine bleach liquor, discarded plant quality of fiber ratio: 4-8: 0.05-0.08: 0.04-0.10: 0.3-7.5: 2-10.
Discarded plant fiber described in the technique scheme is waste wood fiber, discarded fluting board, office and life waste paper, discarded plant stalk etc.
Total Water described in the scheme is dissolved urea, sodium hydroxide and disperses the used Total Water of starch.
Advantage of the present invention is: 1, make oxygenant with clorox, its price is more cheap than other oxygenants, and the source is sufficient; 2, production technique of the present invention is simple, helps scale operation; 3, the used raw material of the present invention is the discarded plant fiber, and not only cost is low, but also has the energy-saving and environmental protection effect, has realized turning waste into wealth truly; 4, the board quality of the present invention preparation is light, and does not contain objectionable impurities such as formaldehyde, can be widely used in industries such as packing, furniture and decoration.
