(3) impact that the nonionic paraffin wax emulsions that the present invention is used for wood modification permeates timber preservative:
Nonionic paraffin wax emulsions used for wood modification prepared by embodiment 1 is watered and is diluted to the different concentration of 1wt%, 3wt%, 5wt%, 7wt%, 9wt% five kinds, and be with mass concentration respectively 1% CCA, ACQ composite, by compositional liquor vacuum pressed process Masson pine timber lab scale material, measure the size of timber with slide measure; Quality before and after being processed with electronic balance weighing masson pine small specimen; Being placed on by treated test specimen in the baking oven of 40 DEG C dries to constant weight, pulverize and clay into power, clear up process, measure the active ingredient of drugloading rate in timber with X-ray energy spectrometer and atomic absorption spectrophotometer etc., draw the basic drugloading rate of timber, disregard the impact of density.Test result is as shown in table 1.
Table 1 paraffin wax emulsions and timber preservative compositional liquor are on the impact (kgm of lab scale material drugloading rate
-3)
As known from Table 1, nonionic paraffin wax emulsions used for wood modification of the present invention is that the drugloading rate of the strong-acid type timber preservative CCA of 1% has impact on mass concentration, along with the raising of nonionic paraffin wax emulsions concentration used for wood modification, strong-acid type timber preservative CCA drugloading rate in wood reduces gradually, mass concentration be 1% ~ 7% nonionic paraffin wax emulsions used for wood modification do not affect preserving timber quality, mass concentration be 9% nonionic paraffin wax emulsions used for wood modification then slightly lower preserving timber quality.The drugloading rate impact of the present invention's nonionic paraffin wax emulsions used for wood modification on strong base timber preservative ACQ is remarkable, and fluctuation range is limited within 0.2, does not affect the quality of preserving timber.
(4) nonionic paraffin wax emulsions variable concentrations used for wood modification of the present invention is on the impact of the anti-bulking factor (ASE) of timber:
Nonionic paraffin wax emulsions used for wood modification obtained for embodiment 1 is watered and is diluted to the different concentration of 1wt%, 3wt%, 5wt%, 7wt%, 9wt% five kinds, be respectively used to vacuum pressed impregnation process Masson pine timber, the anti-bulking factor (ASE) of timber after the nonionic paraffin wax emulsions process used for wood modification of the different amount of detection interpolation, anti-bulking factor calculates by formula (a) ~ (c) of application described in (1), and testing result is as shown in table 2.
Table 2 processes the anti-bulking factor of rear timber
As can be seen from Table 2, along with the increase of paraffin wax emulsions vacuum pressed impregnation process mass percent, namely increase to 9wt% from 1wt%, the ASE of timber is increased to 80.7% from 58.8%.Know by inference thus, nonionic paraffin wax emulsions used for wood modification of the present invention can strengthen the dimensional stability of timber.
(5) impact of the composite anti-bulking factor (ASE) on timber of the nonionic paraffin wax emulsions used for wood modification of 1wt%ACQ and variable concentrations:
Nonionic paraffin wax emulsions used for wood modification obtained for embodiment 1 is watered and is diluted to the different concentration of 1wt%, 3wt%, 5wt%, 7wt%, 9wt% five kinds, for vacuum pressed impregnation process Masson pine timber after composite with 1wt%ACQ respectively, the anti-bulking factor (ASE) of timber after the nonionic paraffin wax emulsions process used for wood modification of the different amount of detection interpolation, the control group not adding nonionic paraffin wax emulsions used for wood modification is provided simultaneously, anti-bulking factor calculates by formula (a) ~ (c) of application described in (1), and testing result as shown in Figure 2.Additive described in figure refers to the nonionic paraffin wax emulsions used for wood modification that embodiment 1 is obtained, and the ratio of fixing 1wt%ACQ, additive progressively increases with 1wt%, 3wt%, 5wt%, 7wt%, 9wt%.
As can see from Figure 2, the ACQ preserving timber not adding nonionic paraffin wax emulsions used for wood modification does not possess water resistance, and the ACQ preserving timber that with the addition of nonionic paraffin wax emulsions used for wood modification has good water resistance.The water repellency adding the ACQ preserving timber of 1wt% nonionic paraffin wax emulsions process used for wood modification improves more than twice than not adding.Along with nonionic paraffin wax emulsions active principle used for wood modification is increased to 9wt% from 1wt%, the water rate of refusing (slip namely absorbed water) of the timber after process brings up to 75.68% rapidly from 59.93%, continue afterwards to be slowly promoted to 79.13%, the water repellency obtained improves 2 ~ 3 times, and the moisture-resistant rate (ASE) that rises rises to the highest by 77.07% by 45.67%.
Above-described embodiment is the present invention's preferably embodiment; but embodiments of the present invention are not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present invention and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
