Description

The nano-TiO of anti-light aging2- ABS composite material

Technical field

The present invention relates to the technical field of composite, and in particular to a kind of nano-TiO of anti-light aging₂- ABS is combined Material.

Background technology

ABS is widely used in the industrial circles such as machinery, automobile, household electrical appliances and building as a kind of thermoplastic engineering plastic, but It is ABS after polyaddition reaction is completed, the higher tertiary carbon allylic hydrogen group of activity is also there is in a small amount of chain link, in photooxidation Easily it is broken butadiene chain link under effect, causes ABS to occur light aging degraded.Therefore the product being made up of ABS is out of doors After long-term use, macroscopical degradation phenomenas such as xanthochromia, cracking, gloss forfeiture and mechanical properties decrease will occur, make originally hot The relatively low ABS material high temperature deformation resistance ability of deformation temperature is further deteriorated, thus ageing-resistant performance quality to a certain degree On determine ABS as the engineer applied scope and prospect of structural material.

It is general in the prior art to use Benzotriazole Ultraviolet Stabilizer and hindered amine type light stabilizer as anti-light old Change, improve the additive of mechanical performance, but such additive not environment protection additive, it is easy to produce to environment and human body There is the material of harmfulness, it is impossible to meet environment-friendly type requirement.

The content of the invention

It is an object of the invention to the problem above for overcoming prior art presence, there is provided a kind of nanometer of anti-light aging TiO₂- ABS composite material, nano-TiO of the invention₂- ABS composite material anti-light aging performance is strong, more environmentally friendly, high temperature deformation resistance, And excellent mechanical performance is taken into account simultaneously.

To realize above-mentioned technical purpose and the technique effect, the present invention is achieved through the following technical solutions：

A kind of nano-TiO of anti-light aging is provided₂- ABS composite material, it is characterised in that：It is by the original of following parts by weight Material composition：

Preferably, being made up of the raw material of following parts by weight：65-75 parts of ABS resin；Nano-TiO₂12-14 parts；It is even Join 0.1-0.3 parts of agent；0.35-0.4 parts of hyper-dispersant.

Preferably, the coupling agent is silane coupler.

Preferably, the hyper-dispersant is modified ethylene bis-fatty acid amides.

Preferably, the nano-TiO of the anti-light aging₂- ABS composite material is also containing other auxiliary agents of 3-5 mass parts, institute Other auxiliary agents are stated for antioxidant, toner, light stabilizer, ultra-violet absorber, the antioxidant is in 1010 or antioxidant PS802 One kind.

A small amount of hyper-dispersant is added in the formula of the present invention and is modified ethylene bis-fatty acid amides, the hyper-dispersant polar group Group and the long chain end of silane coupler produce very strong attraction by Van der Waals, and the attraction is enough to make two thing boundaries disappear Lose, and form a phase, the one of TAF (modified ethylene bis-fatty acid amides) solvation has certain intermiscibility with ABS resin, TAF has played phase solvent.

Nano-TiO₂Nano-particle easily reunite, reduce its and play anti-photooxidation ability, the nano-TiO in formula₂ In the presence of TAF, its Surface Layer Atomic Structure is further reconstructed, and anchor is closed between the reconfigured geometry and ABS resin, is formed more Anchoring node, i.e. crosslinking points further improve ABS resin and nano-TiO₂Between stability, and now also prevent Nano-TiO₂Nano-particle between agglomeration, given full play to nano-TiO₂Anti-light aging ability, the change of composite Learn property more stable, be less susceptible to occur photo-aging phenomena.

The nano-TiO of anti-light aging of the present invention₂The beneficial effect of-ABS composite material is：

(1) addition rutile type nano TiO₂As a kind of light stabilizer, it has the superiority of long-acting shielding ultraviolet rays Can, and had more relative to traditional anti-aging modifying agent such as Benzotriazole Ultraviolet Stabilizer and hindered amine type light stabilizer Environment-friendly advantage；

(2) nano-TiO of the invention₂- ABS composite material can take into account stronger anti-light aging performance, environmental protection simultaneously, resist High temperature deformation and take into account excellent mechanical performance；

(3) nano-TiO of the invention₂- ABS composite material product stability is stronger, is not pulverized easily, and service life is longer, The use scope of composite is not relatively low and limited by ABS heat distortion temperatures, and the scope of application is wider.

Described above is only the general introduction of technical solution of the present invention, in order to better understand the technological means of the present invention, And can be practiced according to the content of specification, embodiment of the invention is shown in detail by following examples.

Embodiment

The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation Example only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common The every other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model that the present invention is protected Enclose.

Raw material are weighed according to the formula ratio of each embodiment in table 1 below, the sample weighed is added in high mixer and mixed 3min, after fully mixing, obtains premix, then premix is transferred in double screw extruder, the extrusion of double screw extruder Temperature is 180 DEG C, and the extrusion rotating speed of double screw extruder is 700 revs/min, and extruding pelletization obtains the nanometer of anti-light aging TiO₂- ABS composite material.

The nano-TiO of the anti-light aging prepared to each embodiment₂- ABS composite material, carries out result verification experiment, presses The standard of table 2 is tested, and the results are shown in Table 3.

The checking test result of table 2

The checking test result of table 3

Nano-TiO prepared by embodiment 1-7 formulas₂- ABS, its mechanical property and anti-light aging performance are obviously higher than right Ratio 1-4.And it was found from being contrasted between embodiment 4 and embodiment 7, in the case where TAF addition is consistent, increase Plus the use of coupling agent is not significantly increased technique effect, only need to add less silane coupler can just reach well Technique effect, because TAF has played phase solvent, with saving the effect that coupling agent is used, TAF and silane coupler The effect that long chain end produces very strong attraction by Van der Waals is, with certain balanced action, more than equalization point, to make With just no longer substantially, but inapplicable one raw material of any of which (is not used in TAF, comparative example 2 in comparative example 1 and silicon is not used Alkane coupling agent) but significantly reduce mechanical property, it follows that the work of Synergistic is served between TAF and silane coupler With interrelated, interaction.

Furthermore, compared with Example 4, in comparative example 3 and be not used nano-TiO₂, photostability be deteriorated, light levels and Vicat temperature is reduced, and thermomechanical stability is deteriorated.Compared with Example 4, nano-TiO in comparative example 4₂Usage amount it is higher, Although bending modulus and notch impact strength change are little, vicat temperature and light levels are reduced on the contrary, illustrate nanometer TiO₂Addition is excessive, it is easier to reunite, and is unfavorable for the performance of its effect.
