The preparation method includes: smashing and grinding organic fiber materials such as rice straws; evenly stirring and blending organic fiber powder, the mountain flour, the talcum powder and the magnesium oxide; adding the additive agents (1 and 2) into the organic fiber powder, the mountain flour, the talcum powder and the magnesium oxide prior to adding water and evenly stirring and blending; filling blended materials into a mould under the condition of harmonic temperature and humidifying temperature prior to cold pressing and forming, and demoulding; performing trimming on a demoulded semi-finished product according to the product specifications; putting the demoulded semi-finished product subjected to trimming performing into a pressure-maintaining and curing mould for curing and warehousing a finished product.
Description
Technical field
The present invention relates to a kind of compound method of rice straw fibrous plate, particularly a kind of compound method of novel rice straw fibrous plate.Belong to building element and decoration technique field.
Background technology
At present, of home make synthetic plate, its raw material overwhelming majority is the raw material that adopts the wood types such as weedtree, sheet material leftover bits and pieces, wood sawdust; Because the raw material sources of wood type are limited by environmental protection and other reason, its quantity delivered is not only limited, and price is higher; So more domestic enterprises and research institution, finding artificial board and other available alternative materials all the time at present.No matter although some enterprises are doing certain trial at the stalk that is utilizing crops manufacturing aspect sheet material, there are some defects at aspects such as intensity, fire-retardant, resistance to acids and bases, water-fast and environmental protection in the sheet material of producing.Its reason is: 1, produce timber intensity poor; 2, fire-retardant rate is low; 3, resistance to acids and bases is poor; 4, water resistance is not strong; 5, sterilization ability is not thorough; 6, do not reach environmental-protecting performance requirement.The present invention is through experimental study, by the stalk of crops by fermentation, sterilizing, abrasive dust mix with inorganic raw material and add after additive, through adding water, mix and stir, packing the shaping of mould mesohigh into, pressurize maintenance becomes a kind of well behaved synthetic plate.
Summary of the invention
The object of the invention is to: the compound method that a kind of novel rice straw fibrous plate is provided, adopt in this way, the sheet material of producing has higher intensity, good anti-anti-flammability, good acid resistance, resistance to water, the environmental-protecting performance of sheet material self all can meet corresponding requirement, overcomes the undesirable defect of product quality that above reason causes.
For achieving the above object, the technical solution adopted in the present invention is: rice straw sheet material is to consist of: rice straw powder, stone flour, talcum powder, magnesia, additive, softening agent, and the part by weight of its formation is: rice straw powder 46%-56%; Stone flour 12%-15%; Talcum powder 5%-10%; Magnesia 25%-33%; Additive (1) 0.2%-0.6%; Additive (2) 0.4%-0.8% forms, and described percentage is weight percentage.
Described rice straw powder forms after being pulverized by rice straw; Described stone flour forms after being pulverized by the leftover bits and pieces of stone; Described talcum powder refers to chemical grade talcum powder; Described magnesia is a kind of bubble PLASTIC LAMINATED special magnesium oxide; Described additive (1) is comprised of 15 parts of glycerine; Described additive (2) is that the ratio in 1: 5 stirs by sulfuric acid and water, in and PH=6.5 form.
The compound method of a kind of novel rice straw fibrous plate of the present invention, its operation principle and manufacture principle are: the first step is pulverized the organic fibrous materials such as described rice straw in proportion, abrasive dust; The second step mixing that in proportion organic fiber powder, stone flour, talcum powder, magnesia stirred; The 3rd step is in organic fiber powder, stone flour, talcum powder, magnesia compound, to add additive (1), additive (2), adds water uniform stirring, mixes; The 4th step is under the condition of mediation temperature and damping temperature, packs described mix into mould, cold-press moulding, the demoulding; The 5th step is that the semi-finished product of the demoulding are carried out to deburring processing by the specification requirement of product; The 6th step is that the semi-finished product that deburring after the demoulding is processed pack maintenance in pressurize maintenance mould into, can finished product warehouse-in.
Beneficial effect: the present invention has been owing to having adopted such scheme, overcome that traditional wood-based plate need to add the defect of the environmental hazard that oxious component formaldehyde brings and poor, the fire-retardant rate of timber intensity produced is low, resistance to acids and bases is poor, water resistance is strong, sterilization ability not thoroughly, do not reach the defect that environmental-protecting performance requires.The stalk of various crops of take is raw material; both solve the conspicuous contradiction of timber supply and demand, protected area of woods, be conducive to again environment; also effectively solve the environmental pollution that brings due to crop straw burning and the defect of stalk resource serious waste simultaneously, reached object of the present invention.Formula compatibility of the present invention and manufacturing process are easy, the alternative timber board of ridged plate, the cement sheet material that produce; Can be widely used in building construction, dividing plate and various decorative panel class industry; Compare with traditional sheet material and there is light, tough and tensile durable, the feature such as price is low of quality; And the effect that meets ecological circulation, and at intensity, fire-retardant, resistance to acids and bases, resistance to water all has very strong effect, is a kind of environment-friendly type synthetic plate of function admirable.
