Abstract
The invention discloses a method for preparing boards by using alkaline gelatinized starch as adhesive and waste vegetable fibers, which is mainly to drip sodium hydroxide at a certain concentration into starch milk to prepare the alkaline gelatinized starch adhesive first, then uniformly mix the prepared alkaline gelatinized starch adhesive and the waste vegetable fiber powder, next place the mixture in a mold and finally prepare the boards by forming and drying. In the invention, the production process is simple and easy to operate, and the boards prepared by the method do not contain harmful substances such as formaldehyde and are environmentally-friendly boards.
Description
Technical field
The present invention relates to a kind of preparation of plates method, particularly relating to a kind of is the method for tackiness agent and discarded plant fiber production sheet material with the alkali pasted starch.
Background technology
Existing decorative sheet adopts plasterboard and wood composite board mostly.Wherein plasterboard intensity is low, and layering comes off easily, and is heavier; Wood composite board contain harmful formaldehyde and thermal and insulating performance poor, yielding, secondly be to adopt cement plate, as the roofing tile plate, though intensity high quality is heavy, fragility is big, toughness is little, bad nailing, construction inconvenience.Also there is shortcoming in existing transportation of cargo packaging plate, because it mostly is wooden (-packing) case or fluting board chest greatly, so must consume a large amount of timber.Above-mentioned sheet material all can consume a large amount of starting material and use and be difficult for later handling or recycling in making processes, not only cause waste, and environment is polluted, and does not meet energy-conservation and environmental protection requirement.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of novel method for preparing sheet material, and this preparation method is a main raw material with discarded plant fiber, starch, sodium hydroxide, obtains sheet material through reasonable proportioning, simple preparation technology.
The technical problem to be solved in the present invention is solved by following scheme: be the method for tackiness agent and discarded plant fiber production sheet material with the alkali pasted starch, it is characterized in that: with dissolution of sodium hydroxide in tap water, make mass concentration and be 40% sodium hydroxide solution, wherein the mass ratio of starch and sodium hydroxide is 1: 0.052-0.156; Starch and tap water are mixed, make starch milk, wherein starch is 1 with the mass ratio of the tap water that disperses starch: 4-8; Under room temperature and the stirring condition, the sodium hydroxide solution that makes is added drop-wise in the starch milk, makes the alkali pasting starch adhesive; Discarded plant blending in of fibers after making the alkali pasting starch adhesive afterwards and pulverizing is even, and wherein starch is 1 with discarded plant quality of fiber ratio: 1.0-6.0, the mixture of mixing is put into mould, and behind shaping and drying, promptly make sheet material.
Technique scheme is described, and the discarded plant fiber mainly refers to the discarded plant fiber in straw, the domestic waste, the discarded plant fiber that industrial production produces; Straw mainly comprises maize straw, wheat stalk, rice straw, cotton stalk etc., discarded plant fiber in the domestic waste mainly comprises useless Corrugated Box, leaf etc., and the discarded plant fiber in the industrial production mainly comprises the potato slag that produces when making starch, the wood chip that the house ornamentation industry produces etc.
Technique scheme is described, and starch can be yam starch, W-Gum, tapioca (flour).
Advantage of the present invention is: with the discarded plant fiber is that raw material and alkali pasted starch prepare building decoration, the transportation of cargo packaging plate, with building decorative plates in the past as timber, stone material, plastic cement and composition board and transportation of cargo packaging plate are as wooden case, Corrugated Box is compared has remarkable advantages, at first, the present invention is raw material and the comparatively practical sheet material of alkali pasted starch preparation with the discarded plant fiber, cost is lower, raw material sources are wide, and existing building decoration, the transportation of cargo packaging plate is that feedstock production forms mostly with the natural resources, the natural resources of consume valuable not only, and physical environment done great damage; Secondly, it is light but still have certain mechanical strength with the panel weight of alkali pasted starch preparation to be raw material with the discarded plant fiber, and easy construction can be sawed, bores, digs, various machine-shapings such as nail are operated, and does not contain harmful material such as formaldehyde; Once more, sheet material involved in the present invention is simple to operate in the process of preparation, required equipment is simple and easy, accomplishes scale production easily; At last, with the discarded plant fiber is that the sheet material of raw material and alkali pasted starch preparation not only has considerable economic, and the method for more in the past handling the discarded plant fiber need take a large amount of land resourcess as: landfill and causes body of groundwater, air to be subjected to severe contamination or burn not only consumption of natural resource but also discharge a large amount of flue dust, obnoxious flavour, suspended particle and compare in air and have immeasurable social benefit.
Embodiment
Embodiment 1: the 15g dissolution of sodium hydroxide in tap water, is made mass concentration and be 40% sodium hydroxide solution; 192g yam starch and 1040ml tap water are mixed, make the yam starch breast, under room temperature and the stirring condition, the sodium hydroxide solution that makes is added drop-wise to the yam starch Ruzhong, make alkali pasting potato Starch Adhesive; Corrugation paper scrap after alkali pasting potato Starch Adhesive and 400g pulverize is mixed, the mixture of mixing is put into mould, behind shaping and drying, promptly make sheet material.The assay of the prepared sheet material of present embodiment is as shown in the table.
Embodiment 2: experiment condition is with embodiment 1, and different is that 180g yam starch and 1040ml tap water are mixed, and makes the yam starch breast.
Embodiment 3: experiment condition is with embodiment 1, and different is that the corrugation paper scrap after alkali pasting potato Starch Adhesive and 600g pulverize is mixed.
Claims (2)
1. with the alkali pasted starch method of tackiness agent and discarded plant fiber production sheet material, it is characterized in that: with dissolution of sodium hydroxide in tap water, make mass concentration and be 40% sodium hydroxide solution, wherein the mass ratio of starch and sodium hydroxide is 1: 0.052-0.156; Starch and tap water are mixed, make starch milk, wherein starch is 1 with the mass ratio of the tap water that disperses starch: 4-8; Under room temperature and the stirring condition, the sodium hydroxide solution that makes is added drop-wise in the starch milk, makes the alkali pasting starch adhesive; Discarded plant blending in of fibers after making the alkali pasting starch adhesive afterwards and pulverizing is even, and wherein starch is 1 with discarded plant quality of fiber ratio: 1.0-6.0, the mixture of mixing is put into mould, and behind shaping and drying, promptly make sheet material.
2. according to claim 1 is the method for tackiness agent and discarded plant fiber production sheet material with the alkali pasted starch, it is characterized in that: the used starch of preparation alkali pasting starch adhesive is yam starch, W-Gum, tapioca (flour).
