Description
Technical field
The present invention relates to wood treatment agent technical field, particularly relate to a kind of water proof fire retardant timber curing agent and preparation method thereof.
Background technology
In recent years, with China's rapid development of economy, the field such as furniture, building materials, decoration grows stronger day by day, and steps up timber, the especially demand of high-quality hard wood, even occurs in that under-supply situation.The quick growing species of trees such as masson pine, China fir, poplar have rapid, the cheap advantage of growth, and alternative natural timber uses, not only has good economic benefit, moreover it is possible to reduce the felling of natural forest, conservation of nature environment.But these quick growing species of trees is wooden relatively gently softer, and its serviceability is typically all poor, and range of application is restricted, for meet faster, the needs of high-quality timber are preferably provided, it is necessary to carry out cure process to it, strengthen hardness and improve performance, expand wood usage.Resin type timber curing agent conventional at present is difficult to degrade in the environment, and containing certain free harmful substance, produces potential hazard to health.It is low with timber adhesion to there is poor permeability in non-resinous timber curing agent, is easy to run off, the problem of persistence difference.And, it is contemplated that timber in actual applications, for improving its safety in utilization and durability, often needs have certain water proof fire retardant, and therefore exploitation safety and environmental protection, persistence timber curing agent good, water proof fire retardant have higher practical value.
Content of the invention
The object of the invention is contemplated to make up the defect of prior art, provides a kind of permeability, persistence good and the timber curing agent and preparation method thereof of water proof fire retardant.
The present invention is achieved by the following technical solutions:
A kind of water proof fire retardant timber curing agent, it is to be prepared by the raw material of following weight parts:
Waterglass 5-10, borax 5-10, magnesium sulfate 10-15, guar gum 2-3, ammonium persulfate 0.1-0.2, titanate coupling agent 0.1-0.2, styrene 2-4, methyl methacrylate 4-6, sodium lignin sulfonate 0.5-1, sodium carboxymethylcellulose 1-2, modified additive 5-10, water 80-100;
Wherein modified additive is prepared by the raw materials in: laurate 0.1-0.2, castor oil 3-5, dimethicone 2-4, nano titanium oxide 1-2, aluminium triphosphate 2-4, cocounut oil acyl diethanol amine 0.5-1;The preparation method of modified additive be nano titanium oxide, aluminium triphosphate are mixed with laurate after add in appropriate absolute ethyl alcohol stirring 20-30min, filter, add remaining raw material 800-1000r/min stirring 10-15min after washing, to obtain final product;
The preparation method of a kind of water proof fire retardant timber curing agent, comprises the following steps:
(1) raw material is weighed by weight, 60-80 DEG C of stirring 1-2h in the water first jointly adding 1/2-2/3 to measure waterglass, borax, sodium lignin sulfonate, guar gum and sodium carboxymethylcellulose, it is subsequently adding magnesium sulfate and ammonium persulfate 50-60 DEG C, 1000-1500r/min stir 1-2h, obtain component A;
(2) water first styrene, methyl methacrylate and titanate coupling agent being added surplus mixes, under the conditions of 600-800r/min, is then slowly added to modified additive stirring 10-15min, obtains B component;
(3) component A and B component are mixed latter 60-70 DEG C, 800-1200r/min stir 2-3h, high speed dispersion be ground to≤20 μm after cooling, obtain water proof fire retardant timber curing agent.
The invention have the advantage that
The present invention first passes through guar gum and sodium carboxymethylcellulose and carries out surface modification to the magnesium hydroxide particulate being formed in solution system, then styrene, methyl methacrylate coating modification again are introduced, obtain timber curing agent after compounding with remaining raw material, the product preparing can form stable overcoat at wood surface, there is good penetrability strong with timber adhesion, not easily run off, the good feature of persistence, hardening effect is good, environmental protection, also there is the effect of water proof fire retardant, safety in utilization and the durability of timber can be improved, there is higher practical value.
Detailed description of the invention
A kind of water proof fire retardant timber curing agent, it is to be prepared by the raw material of following weight parts:
Waterglass 5, borax 5, magnesium sulfate 10, guar gum 2, ammonium persulfate 0.1, titanate coupling agent 0.1, styrene 2, methyl methacrylate 4, sodium lignin sulfonate 0.5, sodium carboxymethylcellulose 1, modified additive 5, water 80;
Wherein modified additive is prepared by the raw materials in: laurate 0.1, castor oil 3, dimethicone 2, nano titanium oxide 1, aluminium triphosphate 2, cocounut oil acyl diethanol amine 0.5;The preparation method of modified additive be nano titanium oxide, aluminium triphosphate are mixed with laurate after add in appropriate absolute ethyl alcohol stirring 20min, filter, add remaining raw material 800r/min stirring 10min after washing, to obtain final product;
