Description

A kind of mothproof modification agent for timber floor timber containing mustard oil

Technical field

The present invention relates to timber floor Wooden modifying process field, be specifically related to a kind of mothproof modification agent and preparation method thereof for timber floor timber containing mustard oil.

Background technology

Timber floor is common fitment material for family, mainly comprise the kinds such as solid wooden floor board, laminated flooring, solid wooden compound floor, due to the core material-timber of timber floor, it is biological material, itself there is inflammable, perishable, yielding, the shortcoming such as wet-heat resisting not, seriously limited its scope of application, necessary timber is carried out to some pretreatment, to improve the timber defensive ability/resistance ability of environment to external world, improve environment tolerance level.

Existing method for modifying wood mainly utilizes some physical means, chemical modification agent solution is infiltrated through to timber inside, reach and improve physics, chemical property, the final object that improves its serviceability, but more existing chemical modification methods timber after treatment, in follow-up use procedure, may have a large amount of volatile organic matter discharges, can produce harm to surrounding environment, also there is inorganic agent high expensive, performance is not lasting, affect the shortcomings such as decorate properties, in the urgent need to developing the Wood modifier of the novel environment-friendly high-efficiency of a class, fundamentally improve the serviceability of timber floor, improve the shortcoming on Traditional Wood floor.

Summary of the invention

The object of the invention is to provide a kind of mothproof modification agent for timber floor timber containing mustard oil, and to improve the serviceability of timber, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of mothproof modification agent for timber floor timber containing mustard oil, it is characterized in that, this modifier is made up of the raw material of following weight portion: sodium sulfite 5-6, NaOH 10-12, urea 35-40, orange osmanthus leaf 1-3, white wine 6-8, mustard oil 0.01-0.02, neopelex 1-2, sodium borohydride 4-5, polyethylene glycol 10-12, water 350-380, auxiliary agent 6-8;

Auxiliary agent is made up of the raw material of following weight portion: nano-tourmaline powder 0.5-1, sodium carboxymethyl starch 6-8, ethoxy urea 12-15, lithium metasilicate 1-2, radix bupleuri oil 1-2, neopelex 2-3, water 30, its preparation method is: first sodium carboxymethyl starch, ethoxy urea, lithium metasilicate, neopelex are mixed with water, being stirred to mixed material dissolves completely, add subsequently radix bupleuri oil, dispersed with stirring 40-50min, finally add nano-tourmaline powder, the mixed solution ball milling 1-1.5h obtaining, make stabilizing solution, obtain auxiliary agent.

Described a kind of mothproof modification agent for timber floor timber containing mustard oil, its preparation method is: first by orange osmanthus leaf and white spirit mixed, airtight immersion 6-8 days, soaks and finishes rear material filtering, and gained filtrate is mixed with sodium sulfite, urea, neopelex, sodium borohydride, water, after being stirred to material and dissolving completely, add again polyethylene glycol, mustard oil, stir 1-2h with the rotating speed of 1500-1800 rev/min, finally add NaOH, continue to stir 30-40min, to obtain final product.

Wood modifier advantage of the present invention is: the safer environmental protection of the more traditional modifier of raw material adopting, not containing volatile toxicant, not harmful to human and environment, in preparation method, utilize soaking in Chinese liquor orange osmanthus leaf, the simple bioactive ingredients with sterilization and anticorrosion effect that extracts efficiently, and the orange osmanthus leaf after soaking can also recycle, avoid the wasting of resources, urea, sodium borohydride, the raw materials such as sodium sulfite, can improve the fire retardancy of timber, promote the combination of inorganic agent and fiber simultaneously, make active ingredient be difficult for running off, the irritant mouthfeel of mustard oil tool, can prevent that timber from damaging by worms rotten, timber safety after the modification agent modification of preparing through the present invention is fire-retardant, anticorrosion mothproof, resistance leachability is good, the timber floor of making is more durable in use with the floor of material, the market competitiveness is strong.

Detailed description of the invention

Embodiment

The modifier of the present embodiment by following weight portion (kilogram) raw material make: sodium sulfite 6, NaOH 12, urea 40, orange osmanthus leaf 2, white wine 8, mustard oil 0.01, neopelex 2, sodium borohydride 5, polyethylene glycol 12, water 380, auxiliary agent 8; Auxiliary agent is made up of the raw material of following weight portion: nano-tourmaline powder 0.5, sodium carboxymethyl starch 8, ethoxy urea 15, lithium metasilicate 2, radix bupleuri oil 1, neopelex 3, water 30, its preparation method is: first sodium carboxymethyl starch, ethoxy urea, lithium metasilicate, neopelex are mixed with water, being stirred to mixed material dissolves completely, add subsequently radix bupleuri oil, dispersed with stirring 50min, finally add nano-tourmaline powder, the mixed solution ball milling 1.5h obtaining, make stabilizing solution, obtain auxiliary agent.
