Abstract
The invention relates to a wood water preventing method, and in particular relates to a manufacture method of a solid-wood water preventing material. According to the manufacture method of the solid-wood water preventing material, wood fibers are adopted to manufacture a framework, an inorganic monomer is filled in the framework and is polymerized with the wood fibers in a crosslinking grafting way when the certain temperature is reached so as to form an integral whole together with the wood fibers, so that the natural performance of wood can be protected, water is prevented, the deformation is avoided, and the wear resistance of the wood is improved. The solid-wood water preventing material with a high mechanical performance and excellent wear resistance can be widely applied to the fields of outdoor furniture, leisure goods, doors and windows, and indoor decoration; low-level wood can be processed to replace high-level wood, and therefore, the national forestry policies are met, and the positive effects on protecting the natural forests are realized; and the cost of the processed wood is lower than that of the high-level wood, so that the solid-wood water preventing material is worthy to promoting.
Description
Technical field
The present invention relates to a kind of method for waterproofing wood, relate in particular to a kind of preparation method of solid wood waterproof material.
Background technology
Natural timber has the natural wood texture, gives nature, soft, texture with affinity, simultaneously because its characteristic cool in summer and warm in winter, that sense of touch is good makes it become the ideal material of finishing and building.But because its weatherability and water resistance are relatively poor, it is relatively narrow that application becomes.The topmost shortcoming of solid wood furniture is exactly yielding, and maintenance is got up difficult.Such as not allowing the sunlight direct irradiation, it is cold overheated to cross, and too dry and moist environment all is not suitable for solid wood furniture; If do not note in use, it is excessive that frequent switch air-conditioning causes humiture to change, even the phenomenon that qualified solid wood furniture product sometimes also can deform, ftracture can say no matter adopt what timber, do manual work and how to investigate, all be difficult to avoid these problems.The heating floor present in the north just can not directly use solid wooden floor board, but solid wood is compound or consolidated floor, and solid wooden compound floor adopts the glue connected mode, and the intervention of adhesive more or less can exert an influence to environment; The consolidated floor chemicals usage is just larger, and does not have the premium properties of solid wood.
Summary of the invention
The object of the invention is to for above-mentioned the deficiencies in the prior art, a kind of timber preparation method with the indeformable good weatherability of waterproof is provided.
The present invention is achieved by the following technical solutions:
A kind of preparation method of solid wood waterproof material may further comprise the steps:
(1) timber reaches below 5% its moisture content through degree of depth oven dry charing;
(2) timber stacking that charing is good leaves the space between timber in vacuum impregnation tank, vacuumizes to reach 80-200Pa pressurize 2-20 hour;
(3) add the maceration extract for preparing in the impregnating autoclave, pressurization 0.2-2MPa, pressurize 4-12 hour, pressure release, timber takes out stand-by;
(4) timber that above-mentioned dipping is good carries out coated by high-molecular film;
(5) timber behind the overlay film is put into drying chamber, under 55-120 ℃ of temperature, the graft crosslinking copolymerization, cooling is taken out after 3-12 hour, is required solid wood waterproof material.
A kind of preparation method of solid wood waterproof material, selected timber can be any kind timber.
A kind of preparation method of solid wood waterproof material, described coated by high-molecular film is to adopt the liquid of paraffin and water soluble polymer to dip, and forms one deck polymer protective film at the wood surface that soaked liquid.
The preparation method of described a kind of solid wood waterproof material, maceration extract is made of following ratio of quality and the number of copies: crosslinking agent 1-100 part, chelating agent 0.5-100 part, initator 1-100 part, look smart 2-80 part, vinyl dipping base fluid 800-1200 part.
A kind of preparation method of solid wood waterproof material, described vinyl dipping base fluid is styrene, and is at least a in vinyl acetate, acrylic acid, acrylamide, acrylic acid (ester) and methacrylic acid (ester) class.
A kind of preparation method of solid wood waterproof material, the preferred EGDMA GDMA of described crosslinking agent or MBA methylene diacrylamide, the preferred EDTA ethylenediamine tetra-acetic acid of chelating agent and alkali metal salt thereof.The preferred azo-bis-isobutyl cyanide of initator or benzoyl peroxide.
The present invention utilizes wood-fibred as skeleton, fills organic monomer, reaches one regularly in temperature; organic monomer and the polymerization of wood-fibred cross-linked graft; form one integrated mass with wood-fibred, namely protected the natural performance of timber, waterproof is indeformable and improved the timber weatherability again.
Dipping base fluid of the present invention is that vinyl monomer is mixed, add crosslinking agent, initator, chelating agent, look smart, selected timber can be any timber, but must be through charing, timber carries out charing in hot environment, because carbonization process has reduced the content of the hydrophilic factor in the timber, reduce the hygroscopicity of timber, slowed down the stress of timber inside, the exchange capacity of carbonized wood and ambient moisture is significantly descended, thereby greatly reduced timber and in use changed the distortion that causes because of moisture, shrink and bulking, can allow the timber through charing in humid air, keep lower moisture content.The inside and outside consistent color of carbonized wood also can guarantee the even of color at whole plate face.The carbonized wood color is the physics colouring, and the color of carbonized wood can not prolong in time and change, and the decorative effect of carbonized wood consistently.Different with technique according to seeds, the color of carbonized wood is yellow to dark-brown.For the fast growing wood of the light color such as pine, birch, can make the precious timber in the torrid zone that is similar in color of these cheap timber after the charing.Because the carbonized wood equilibrium moisture content is low, the moisture content during use is also lower, so bending strength and Deflection Modulus of Elasticity when the charing treatment temperature that is fit to can improve the carbonized wood use.The crosslinking agent effect is to make linear polymer laterally crosslinked, and polymer is more stable.The look essence is that commercially available shades of colour liquid color is smart.Different according to selected trees, the adjusting process parameter is to reach optimum efficiency.
Key problem in technology of the present invention is: dipping is even, and the mixed solution that is exactly organic monomer fully is mixed, and the vacuum of timber is necessarily high, under certain pressure, just can reach evenly like this, and this relates to the finished product rate; Coated by high-molecular film prevents the monomer volatilization, and it must be all standing that overlay film requires; Initiated polymerization, temperature will be controlled well, prevents implode, affects properties of product.
The present invention is widely used in outdoor furniture, leisure goods, door and window, the fields such as interior decoration with its mechanical performance height and good weatherability.Low-grade timber can substitute high-grade timber through processing, and meets China's forest policy, plays positive role for natural forest protection.Be lower than high-grade timber price after the processing and have fine promotional value.
