Abstract
The invention provides a low-breakage-rate high-hardness talcum powder master batch and a preparation method and application thereof. According to the invention, by optimizing the formula of the auxiliary agent (comprising the adhesive, the lubricant and the coupling agent), the talcum powder master batch with high talcum powder content, low breakage rate and higher hardness can be prepared, wherein the breakage rate of the prepared talcum powder master batch after 2m of height falls is less than 5%, the problems of talcum powder bridging and caking in the production process of filling the talcum powder into the plastic composite material can be greatly improved, and the performance of the prepared plastic composite material is better.
Description
Technical Field
The invention belongs to the field of plastic additives, and particularly relates to a low-breakage-rate and high-hardness talcum powder master batch as well as a preparation method and application thereof.
Background
The talcum powder is one of the most common fillers of modified plastics, and can improve the rigidity, hardness and dimensional stability of the material. The modified polypropylene composite material filled with the talcum powder is widely applied in the fields of automobiles, household appliances, daily necessities and the like.
Compared with the common talcum powder, the polypropylene material modified by the fine/superfine talcum powder has higher rigidity, higher heat distortion temperature, higher toughness and more excellent comprehensive performance. However, the fine/superfine talc powder has small particle size, small bulk density and poor flowability, which causes the following abnormalities in the production process of the superfine talc powder filled polypropylene material: 1) poor productivity smoothness: the talcum powder bridges and agglomerates to cause blanking blockage; 2) poor dispersion of the talcum powder in the double-screw extruder causes material extrusion and strip breakage; 3) the production environment is poor: the fine/superfine talcum powder is seriously dusted in the using process, the production operation environment is influenced, and the health of workers is damaged. The above-mentioned abnormalities result in a great reduction in the production efficiency and yield of the material.
The talcum powder is prepared into master batch, which can solve the problems to a certain extent. However, the common talc master batch usually uses a resin matrix (such as PP or PE) as a carrier, the content of talc can only reach about 80 wt% at most, for example, a talc master batch TYPP80 sold in Tianjin is available, the content of talc can only reach 80% by adopting an internal mixer process, and the master batch has a higher melt index by using PP EP548RQ as a base material, so that the master batch cannot be applied to low-melt-index extrusion profile products; and the carrier proportion in the master batch is too high, which causes the preparation cost to be higher and is not beneficial to large-scale production.
At present, although there is an attempt to select a suitable additive to replace the resin carrier to prepare an unsupported master batch, for example, chinese patent CN104212034A, a plasticizer (50-80 wt%) and a functional assistant are mixed, and subjected to melt granulation to prepare an assistant master batch, wherein the plasticizer is at least one of stearic acid, petroleum, fatty acid monoglyceride, stearate, pentaerythritol stearate, polyethylene wax, petroleum resin, and polyethylene glycol. Although the method reduces the influence of the resin carrier in the master batch on the performance of the prepared composite material to a certain extent, the method does not disclose how the crushing resistance of the prepared master batch is, and if the prepared auxiliary master batch is fragile, on one hand, the auxiliary master batch is easy to crush in the process of preparing the composite material and is not uniformly dispersed in a resin matrix, so that the performance of the prepared composite material is influenced; on the other hand, the addition amount of the plasticizer is more than 50 wt%, and too much addition amount of the plasticizer also influences the performance of the filler.
In addition, Chinese patent CN101792536A discloses a carrier-free talcum powder master batch, wherein 15-35 wt% of additive and 65-85 wt% of talcum powder are stirred and mixed, and the carrier-free talcum powder master batch is prepared by melt extrusion, and the content of the talcum powder in the prepared master batch can reach more than 98 wt%. Although the content of the talcum powder in the master batch prepared by the method is high, the used additive contains a large amount of water, so that the formed master batch is easy to crack in the drying process, the master batch cannot be used, and the yield of the master batch is reduced to a great extent.
Therefore, the development of a talc powder masterbatch which is easy to produce, low in breakage rate, high in filler content and high in adhesive strength, has good compatibility with a resin matrix, can be uniformly dispersed in the resin matrix, and improves the performance of the composite material is required.
Disclosure of Invention
In order to overcome the defects, the invention provides the master batch with low breakage rate and high hardness, which is easy to produce and has low breakage rate and high adhesive strength.
The invention also aims to provide a preparation method of the master batch with low breakage rate and high hardness.
The invention also aims to provide the application of the low-breakage-rate high-hardness talcum powder master batch in preparing plastic composite materials.
In order to achieve the purpose, the invention adopts the following technical scheme:
a low-breakage-rate and high-hardness talcum powder master batch comprises the following components in parts by weight:
wherein the adhesive is one or the combination of two of naphthenic oil or paraffin oil; the dispersing agent is one or a combination of more of ester dispersing agent or stearate; the coupling agent is one or a combination of more of a silane coupling agent or a maleic anhydride grafting modifier.
Through a large number of experimental researches, the inventor of the invention discovers that the proper adhesive, dispersant and silane coupling agent are selected to be matched, and under the synergistic action of the adhesive, the dispersant and the silane coupling agent, on one hand, the adhesive strength of the talcum powder master batch can be improved, the crushing rate is reduced in the production process, the storage process, the transportation process and the application process of the talcum powder master batch, and the yield and the qualified rate are improved; the problems of talc powder bridging and caking in the process of filling the resin matrix with the talc powder master batch can be thoroughly solved, and the stability of the composite material in the production process is improved; the talcum powder master batch can be well dispersed in a resin matrix, and the mechanical property of the polymer material is obviously improved.

The results are detailed in table 5.
TABLE 5 results of Performance test
As can be seen from the results of table 5:
the results of the above examples show that, within the dosage range of the invention, the molding rate and the breaking rate of the prepared talcum powder master batch and the mechanical property of the master batch prepared by the method are good, wherein the molding rate is over 96.5 percent and can reach 100 percent; the breaking rate is below 5 percent and can be as low as 2 percent; the tensile strength is more than 24MPa and can reach 26.8 MPa; at the same time, the impact strength is 17KJ/m2Above, up to 26.5KJ/m2。
Specifically, the method comprises the following steps:
the results of examples 3-6 show that: along with the increase of the content proportion of magnesium stearate in the dispersing agent, the forming rate level is stable and good, and the crushing rate shows the trend of descending first and then ascending; the impact strength and the tensile strength of the composite material prepared by the method show a rising trend and gradually tend to be stable; therefore, the dispersant (as in example 3) with proper proportion can make the master batch have better comprehensive performance.
A comparison of example 3, examples 7-14 shows that: the dosage proportion among the adhesive, the dispersant and the coupling agent has certain influence on the performance of the material, and specifically: with the increase of the dosage proportion of the dispersing agent (examples 7-10), the molding rate of the master batch is relatively stable; the crushing rate is slightly increased; the impact strength gradually rises; the tensile strength is stable after being slightly reduced, and the prepared master batch has better tensile and impact properties at the same time by the proper addition amount of the dispersing agent (as in example 9).
With the increase of the proportion of the use amount of the coupling agent (example 9, examples 11-14), the change of the forming rate and the breaking rate of the prepared master batch is not obvious; the tensile strength shows a rising change trend, and the rising rate is gradually increased; the impact strength of the notch is in a descending trend, and the descending rate is gradually reduced along with the increase of the dosage of the coupling agent; therefore, by selecting the proper amount of the coupling agent (e.g., examples 9 and 13), the prepared masterbatch has better tensile and impact properties.
The comparison between examples 15-23 and comparative examples 1-10 shows that the selection of the types of the binder, the dispersant and the coupling agent has a certain influence on the performance of the master batch, the selection of the proper types of the binder, the dispersant and the coupling agent can obviously improve the performance of the master batch, and the results of examples 18-20 show that the effect of mixing the ester dispersant and the stearate dispersant is better.
The results of examples 24-26 show that talc selection has less impact on performance, indicating that the present solution is applicable to talc of various particle sizes. The mold release agent has little influence on the molding rate and the breakage rate.
