Abstract
The invention belongs to the field of building materials and relates to a board for a room door. The board for the room door is characterized in that the board is prepared by using wheat straw particles as the raw materials, adding a certain amounts of polyvinyl alcohol adhesive and low alkalinity cement hardener and a right amount of water and processing the materials; and a composite reinforcement layer is laid on the surface of a slab. The board has the obvious advantages that agricultural waste straws are utilized; no formaldehyde is released; the flame retardance is good; the strength can meet the requirement; the cost is reduced; and the like. The board is a novel room door board for saving energy, reducing the emission and developing the low carbon economy.
Description
Technical field
The invention belongs to building material field, relate to sheet material, be specifically related to a kind of door plate.
Background technology
Along with social development and the people the level rise of living, being used for door increases day by day with the plate demand, and forest products wood plank resource poorness day by day.
The problem that lacks in order to solve forest products timber, artificial door is come out one after another with plate.
The sham wood shaving board adopts the wood working tankage more, such as wood shavings, sawdust etc., but need to use a large amount of tackiness agents, and tackiness agent is because containing formaldehyde, discharges the user is occupied the people environment is caused serious harm and to pollute afterwards.
Along with the scale operation of sham wood shaving board, the wood working tankage such as wood wool also are becoming tight day, and supply falls short of demand, and the sham wood shaving board is uncomfortable as the door plate.
People begin again to utilize stalk to make raw material, adopt urea-formaldehyde resin, isocyanic ester to make artificial stalk board as tackiness agent.Existing artificial stalk board is not suitable for as the door plate, and which problem does artificial stalk board exist?
1, urea-formaldehyde resin is more because of surperficial waxy substance and dioxide-containing silica for stalk raw materials, and binding property is bad, and has formaldehyde to discharge;
2, isocyanic ester has solved the binding property problem, but serious sticking to mould problem appears again in the demoulding; Isocyanic ester is owing to price, and cost is high, and the density of stalk is less, only is 1/4th to 1/5th of wood wool, and less resin added is difficult to be evenly distributed;
3. relatively poor because of the isocyanate adhesive tack, the in addition cured matter in stalk surface, cause artificial stalk board slab initial strength poor, again because door is thinner with plate, the broken plate of easily loose base in storing and use procedure, artificial stalk board is uncomfortable as special building door plate, applies being subject to certain restriction.
Summary of the invention
The contriver is in the research process of material of construction, find that existing artificial stalk board exists certain defect, constantly explore, repetition test, purpose is to develop a kind of door plate, can utilize discarded stalk to make raw material, solves preferably the binding property to stalk, improve the intensity of sheet material, and problem of environmental pollution.
The technical solution used in the present invention is, a kind of door plate adopts following weight part raw material to make: Wheat Straw particle 10-30, and poly (vinyl alcohol) binder 1-3, low alkalinity cement solidifying agent 30-70, water is an amount of.
The door of making at above-mentioned raw materials applies with the surface of plate and adds the composite strengthening layer.
The present invention adopts above technical scheme and measure, and the wheat straw that adopts or straw stalk particle have reduced the cured matter on surface etc. through the mechanical disruption processing, make it to be easy to bonding; The tackiness agents such as the polyvinyl alcohol that adopts have not only avoided containing formaldehyde binder, have solved binding property and sticking to mould problem, and price is lower again, is convenient to control resin added; The low alkalinity cement that adopts or terra alba solidifying agent, can promote to accelerate tackiness agent to the curing of raw material, improved the initial strength of door with the plate slab, play again simultaneously the fire retardant effect, thereby the binding property that has solved preferably stalk reaches the mould sticking to mould, improve the intensity of door with plate, reduced the problems such as cost and environmental pollution; The present invention sets up the composite strengthening layer at described door with the surface of plate, has further increased the intensity of door with plate, has improved quality product and result of use, thereby has improved the transforming degree that utilizes of discarded stalk.
Embodiment
Door of the present invention adopts following weight part raw material to make with plate: Wheat Straw or straw stalk particle 10-30, and polyvinyl alcohol or polyvinyl butyral acetal or urethane or Starch Adhesive 1-3, low alkalinity cement or terra alba solidifying agent 30-70, water is an amount of.
Door of the present invention plate embodiment 1, adopt following weight part raw material to make: Wheat Straw or straw stalk particle 10, polyvinyl alcohol or polyvinyl alcohol butyraldehyde or urethane or Starch Adhesive 1, low alkalinity cement or terra alba solidifying agent 30, water is an amount of.
Door of the present invention plate embodiment 2, adopt following weight part raw material to make: Wheat Straw or straw stalk particle 30, polyvinyl alcohol or polyvinyl alcohol butyraldehyde or urethane or Starch Adhesive 3, low alkalinity cement or terra alba solidifying agent 70, water is an amount of.
Door of the present invention plate embodiment 3, adopt following weight part raw material to make: Wheat Straw or straw stalk particle 20, polyvinyl alcohol or polyvinyl alcohol butyraldehyde or urethane or Starch Adhesive 2, low alkalinity cement or terra alba solidifying agent 50, water is an amount of.
Door of the present invention is laid the composite strengthening layer that cloth or paper, fiber, rete and coating waterproof antiwear dope layer are made surperficial strongthener with plate embodiment 4 on the surface of the floor tile slab that adopts above-described embodiment 1-3 to make.
Door of the present invention adopts following fabrication processing with plate embodiment 1-3: Wheat Straw particle-add tackiness agent, water mix-add solidifying agent mix-pour into door with board mold-5MPa with upward pressure compression moulding-maintenance-one-tenth slab-finishing-finished product door plate.
The door of the embodiment of the invention 4 adopts following fabrication processing with plate: use in the plate fabrication processing at embodiment 1-3 door, or before pouring into, raw material in mould, spreads first compress or paper, fiber surface strongthener, or behind the one-tenth slab, add compress or paper or fiber-reinforced layer at slab or production board surface, at above-mentioned enhancement layer coating waterproof antiwear dope layer, consist of a kind of composite strengthening layer again.
The made door of the present invention plate sample is through pressing the test of GB/T11718-2009 method, MOR 〉=14.5MPa, plane tensile strength 〉=0.45MPa, thickness swelling rate≤2.0%, burst size of methanal does not detect, and index of correlation reaches and is better than the performance of national standard.
The present invention utilizes a large amount of agriculture waste stalks to make the compound door plate of ecological, environmental protective of zero burst size of methanal, turn waste into wealth, do not need to consume the too many energy, Sustainable development, it is the rare Novel door plate of development energy-saving and emission-reduction low-carbon economy, in case apply, will give play to obvious advantage, produce significant economic results in society.
