Abstract
The invention provides a method for manufacturing a straw compound material fire-proof plate. The method comprises the steps of: using the straws which have a certain size and shape and the hair as the raw materials; mixing the straws and hair with modifier, gypsum and urea-formaldehyde resin into pasty; coating the pasty mixture on a stacked yarn; and pressing and molding. The surface of the straw compound material fire-proof plate is stuck with a decorative layer. The plant straw is used as the raw materials and has the energy-saving and environment-protection functions.
Description
Technical field
The present invention relates to a kind of construction substrate, specifically, relate to a kind of production method of utilizing the straw compound material fire-proof plate of straw preparation.
Background technology
China is the country of Shaolin, the forest reserves are very valuable, there is bigger contradiction between the timber supply and demand, stalk then belongs to renewable resource, and all can produce a large amount of stalks every year, except that being recovered on a small quantity the utilization, most stalk is all burned or is discarded, both caused the waste of resource, and polluted environment again, development is that the stalk constructional materials of raw material is one of effective way that solves this contradiction with the stalk.Existing beaverboard preparation mainly contains three kinds: i.e. dry method, semidry method and wet method.Dry production all adds the glue hot-press solidifying and becomes plate, and the aldehyde adhesive of Shi Yonging is harmful in process of production, and the isocyanates cost is higher.Patent publication No. is CN1069220, CN134866A, CN140374A, CN1089663C, CN1403255A, CN11280046, what relate to is the processing method of different wood, bamboo, straw fiber and sheet material, all adopt to add glue,, be solidified into the dry method production process of plate by isocyanates replaced the containing hazardous substance glue of formaldehyde.Semidry method is produced, and the easy conglomeration of the fiber quite difficulty of suitability for industrialized production of mating formation adds the restive constant that reaches of moisture content, and the product homogeneity can't guarantee, is not used for suitability for industrialized production so far.Wet production is owing to water consumption in the fiber production process is big, and contaminated environment is with disabled; And internal layer is soft in the middle of the sheet material of wet production, table, the hard layering inequality of pericentral siphon, and decorative effect is not good.But because product is exempted from the glue environmental protection, cost is low, and bigger market is arranged.So the fiberboard process that haves much room for improvement, improve the quality of products.
Summary of the invention
The production method that the purpose of this invention is to provide a kind of straw compound material fire-proof plate with discarded stalk recycling, is made the various construction substrate of society need, realizes turning waste into wealth.
The production method of straw compound material fire-proof plate of the present invention, to cut into the stalk of certain size and shape, hair is a raw material,
Use modifier, gypsum, Lauxite and above-mentioned stalk, hair are mixed into pasty state,
With above-mentioned pasty mixture the stratiform gauze is bonded together, repressed moulding,
Described modifier is the aqueous solution of magnesia, magnesium chloride
Said straw compound material fire-proof plate surface is bonded with decorative layer.
Said straw is selected from one or more in wheat straw, straw, cotton straw, corn stalk, rape straw, beanstalk, sugarcane straw, castor-oil plant straw, numb straw, reed straw, sorghum stalks, rice bran, husk, rattan and the bamboo chip.
The straw compound material fire-proof plate that the production method of straw compound material fire-proof plate of the present invention is produced has the purposes as all kinds of floors of indoor and outdoor, all kinds of decorative panel, concert hall and conference room abatvoix, stair, door, waterproof fireproofing body of wall, anti-vibration house, packaging material, guardrail and waterproof fireproofing table top.
The production method of straw compound material fire-proof plate of the present invention has following technique effect:
1, with straw as primary raw material, have energy-conservation and dual-use function environmental protection;
2, owing to use the macromolecule adhesive of high-adhesive-strength, make straw compound material fire-proof plate of the present invention have long service life, in light weight, mechanical performance is high, save material, cost is low, insulation, sound insulation, fire resistant flame retardant, pollution-free, nuisanceless, characteristics such as simple are installed, and have good anti-ly damage by worms, waterproof and antiseptic property.
3, the straw compound material fire-proof plate plasticity of the production method of straw compound material fire-proof plate of the present invention production is strong, can be made into different shape replacing wood and multiple light building material, building materials such as stalk floor, stalk stair, stalk plate, stalk door, straw wall, stalk lamppost, speedway stalk guardrail, dwelling house stalk fence, waterproof table top, antidetonation type stalk house, packaging material, indoor and outdoor ornament materials be can be used to be made into as required, furniture, boats and ships, tubing and the multiple field that needs framing component also can be applicable to.
The specific embodiment
Embodiment 1
By weight ratio:
Stalk 18%, hair 2%, mull 20%, magnesia 28%, magnesium chloride 18%, gypsum 9%, Lauxite 5%
Technological process
Stalk → select materials → clear water is washed → is pulverized → screening → fine fodder of looking over so as to check (powdery)
(0.2-2cm) washed → cut short to hair → select materials → clear water
Stalk fine fodder, the short material of hair are mixed, stir → compound
Modifier: the water of getting magnesium chloride 28% usefulness 62% by weight is dissolved as magnesium chloride solution (concentration is 28%), add magnesia 28% again and get modifier 70%, add compound 30%, the gypsum 9% starchiness solvent that stirs adds 5% the Lauxite that weight is magnesia weight → stir → secondary starchiness solvent again and gets 1/6 of 1/3 secondary starchiness solvent earlier by 1/3 secondary starchiness solvent of straw compound material fire-proof plate gross weight in the starchiness solvent, be sprinkled upon and lift on the plate, even with the row brush brushing, mull is paved on secondary starchiness solvent, getting 1/6 of 1/3 secondary starchiness solvent again is sprinkled upon on the mull, even with the row brush brushing, with the claying plate mull is evenly flattened again, compacting.With above-mentioned same operating procedure, spread 5 layers of mull continuously, sprinkle secondary starchiness solvent, natural coagulation at room temperature 12 continuous 6 times---15 hours, straw compound material fire-proof plate is taken off from lifting plate, in the clear water of room temperature, soaked 5-7 hour, pull straw compound material fire-proof plate out from water, at room temperature dry or dry, dry at drying chamber winter, size cutting edge in accordance with regulations, the packing warehouse-in.
