Abstract
A method for preparing composite wood comprises the following steps: a polymer and an additive composite are mixed to form a mixture, wherein the additive composite comprises a component with a polyisocyanate group and a hindered amine component with a reaction functional group, and the reaction functional group in the hindered amine component with the reaction functional group comprises at least one of the following groups as follows: hydroxyl, a thiol group and amino; the component with the polyisocyanate group and the hindered amine component with the reaction functional group in the mixture are subjected to an addition reaction.
Description
Technical field
The present invention relates to a kind of method for preparing composite wood, more particularly to a kind of to prepare answering with light stability
The method for closing material.
Background technology
In macromolecular material, polyolefin has preferably endurance and engineering propertiess, and becomes the height being extensively utilized
Molecular material.However, polyolefin is during processing or the finished product that is made from it is during use, easy light affects,
Cause to have yellow, the problem of aging or brittle iso-metamorphism to produce.
The method that the Patent Case that U.S. Patent Bulletin number the 6051164th discloses a kind of stable polymer product of manufacture.Should
Method is comprised the steps of：By polymeric material, the o- aromatic radical of hydroxyl-three triazine light absorber (ortho hydroxy
Tris-aryl triazine light absorber), hindered amine as light stabilizer (hindered of the molecular weight more than 500
Amine light stabilizers) mixing, the hindered amine as light stabilizer and the o- aromatic radical of hydroxyl-three triazine light absorber

Assessment item
Elongation to break value loss rate (%)：By the composite wood of embodiment 1 to 18 and comparative example 1 to 18 respectively with ASTM
It is the test piece to be measured of 2mm that D638 IV standard testing maneuvers prepare thickness, and is respectively implanted measurer for pulling force (equipment：High ferro science and technology
Limited company；Model：AI-7000S) carry out pulling force measurement, and draw speed be 100mm/min, gained elongation to break value
For T0.By this etc., to be tested is respectively implanted xenon light fugitometer (ATLAS Model Ci3000 Xenon
Fadeometer the xenon light irradiation for), and with ASTM G155 standard testings maneuvers carrying out 5000 hours.It is after irradiation, this etc. is to be measured
Test piece is respectively implanted measurer for pulling force, carries out pulling force measurement, and draw speed is 100mm/min, and gained elongation to break value is T1.
The elongation to break value loss rate is [(T0-T1)] × 100%/T0.
From the experimental data of the embodiment 1 to 9 of table 1, by polymer (A) once with this have it is polyisocyanate-based
Component (B) and the amine system component (C) of being obstructed should with reactive functional group base mix, and should have polyisocyanates in mixed process
The component (B) of base and the amine system component (C) of being obstructed that should have reactive functional group base carry out the composite wood Jing 5 that additive reaction is formed,
After the xenon light irradiation of 000 hour, elongation to break value loss rate is 44.12% to 50.23%.
From the experimental data of the embodiment 10 to 18 of table 2, the polymer (A) of part first had into polyisocyanic acid with being somebody's turn to do
The component (B) of ester group and amine system component (C) mixing of being obstructed with reactive functional group base, and should have many isocyanides in mixed process
The component (B) of perester radical and the amine system component (C) of being obstructed that should have reactive functional group base carry out additive reaction, add remaining poly-
After the composite wood Jing xenon light irradiations of 5,000 hour that compound (A) is formed, elongation to break value loss rate be 30.12% to
65.12%.
From the experimental data of the comparative example 5 to 12 of table 3, this is had into polyisocyanate-based component (B) and is had
The amine system component (C) of being obstructed of reactive functional group base mixes and carries out after additive reaction formation addition compound product, adding polymer (A) institute
After the composite wood Jing xenon light irradiations of 5,000 hour of formation, elongation to break value loss rate is 84.65% to 90.15%.
From the foregoing, the elongation to break value Jing after irradiation of the composite wood obtained by the method for preparing composite wood by the present invention is damaged
Mistake rate is low, so the present invention prepares the method for composite wood and composite wood can be made to have preferable light stability really.Furthermore, in the present invention
Prepare to be divided in polymer (A) in the method for composite wood and add twice, elongation to break value loss rate after irradiation can be caused lower, after
And make composite wood that there is more preferably light stability.
In sum, while mixing with polymer (A) by auxiliary agent constituent, make this that there is polyisocyanate-based group
Divide (B) and the amine system component (C) of being obstructed with reactive functional group base to carry out additive reaction, form an addition compound product, and the addition is produced
Thing can be dispersed in the polymer (A), the polymer (A) is effectively protected then so that the composite wood for being formed has
Light stability, and be unlikely to deteriorate, so the purpose of the present invention can be reached really.
