Description
Technical Field
The present invention relates to the field of deodorizing, more specifically, the present invention relates to C08K9/12.
Background
The CN201711428464 is added with the first deodorant and the second deodorant in the modification preparation process of the polypropylene, so that the obtained composite material has low odor grade, however, the composite material adopts various deodorants, the raw material types are complex, and the operation is not easy. CN201910267119 achieves the effect of low odor emission by adding the reaction type odor removing agent, the physical adsorption type odor removing material and the porous water-rich master batch, and the raw materials are more complex, so that the odor removing effect is easily influenced by misoperation in the adding and using process. Therefore, there is a need to provide a deodorizing master batch that is simple in raw materials and safe to use.
Disclosure of Invention
In view of the problems of the prior art, a first aspect of the present invention provides a liquid extractant-loaded deodorizing masterbatch comprising a liquid extractant-loaded polyolefin porous material.
In one embodiment, the liquid extractant comprises (a) water and/or (b) a compound of the structure shown in formula (1);
Wherein R 1-R4 is independently selected from any one of H, hydroxy, alkylhydroxy, substituted or unsubstituted C 1-3 alkyl, and R 1 and R 3 are not both H; and M is C or Si.
Preferably, the unsubstituted C 1-3 alkyl is methyl or ethyl.
Preferably, the boiling point of the liquid extractant is 70-140 ℃.
Further preferably, the compound of the structure of formula (1) includes isobutanol and triethyldodecanol.
Preferably, the weight ratio of the isobutanol to the triethylcinnamyl alcohol is (0.1-0.5): 1. more preferably 0.2:1.
Preferably, the weight ratio of the water to the compound of the structure shown in the formula (1) is 1: (0.8-1.2), more preferably 1:1.
The applicant found in experiments that in order to effectively reduce the odor level of polypropylene, it is necessary to use different types of odor removing agents, such as an extraction type odor removing agent and a reaction type odor removing agent, or an extraction type odor removing agent and an adsorption type odor removing agent, but the use of a plurality of odor removing agents is complicated, and the use of a single type of odor removing agent is not ideal in odor removing level, especially after the polypropylene obtained by the odor removing masterbatch treatment is treated at high temperature for a period of time, the odor release amount is great, and the applicant found in experiments unexpectedly that when the liquid extractant comprises water and a compound having a structure as shown in formula (1), and R 1 and R 3 are not simultaneously H, especially the liquid extractant comprises water, isobutanol and triethylcinnamyl alcohol, and the weight ratio of isobutanol and triethylcinnamyl alcohol is (0.1 to 0.5): 1, the weight ratio of water to the compound of the structure shown in the formula (1) is 1: (0.8-1.2), the polypropylene treated by the deodorizing master batch has lower odor grade when the deodorizing master batch of a single type is used, and meanwhile, even if the treated polypropylene is placed for a period of time under high temperature, the odor grade is unchanged, so that the problems that the effect of lower odor grade and high odor release amount under high temperature can be achieved by adopting a plurality of types of deodorizing agents in the prior art are avoided, and the applicant considers that possible reasons are that specific and different branched side chains exist among water, isobutanol and triethylcinnamyl alcohol and have different polarities, and can act on small molecular substances with relatively large molecular weight in the process of acting with volatile organic compounds, so that the stronger Van der Waals force between the small molecular substances and the polypropylene is destroyed, and the purpose of separation is achieved.
In one embodiment, the liquid extractant comprises 60 to 70wt% of the deodorizing masterbatch.
Preferably, the liquid extractant comprises 67wt% of the odour-combating masterbatch.
The polyolefin type of the polyolefin porous material described in the present application is not particularly limited, and may be selected conventionally by those skilled in the art.
In one embodiment, the polyolefin porous material has a melt strength of 25cN or greater.
Preferably, the polyolefin porous material has a cell distribution density of 80 cells/cm 3 or more.
Preferably, the polyolefin porous material has a cell size of 40 to 70. Mu.m, more preferably 40 to 45. Mu.m.
In one embodiment, the polyolefin porous material is a polyethylene porous masterbatch.
The polyethylene porous master batch can be self-made or purchased, and the preparation method of the polyethylene porous master batch can be selected conventionally by a person skilled in the art.
The liquid extractant comprises isobutanol, the smell of the liquid extractant is found to exist in the liquid extractant during the experimental operation, so that the experimental operator is influenced, the content of the liquid extractant is reduced, when the liquid extractant accounts for 60-70wt% of the deodorizing master batch, the deodorizing effect is reduced to a certain extent, the applicant surprisingly found that when the liquid extractant with specific types and specific contents is used, the polyolefin porous material with the pore size of 40-45 mu m is combined, and the odor grade of polypropylene can be effectively reduced by adding the deodorizing master batch during the modification of polypropylene, the applicant considers that the possible reasons are that the mutual synergistic effect between the polyolefin porous material with smaller pore size and the specific liquid extractant molecule is better, the surface acting force of the liquid extractant molecule and the polyolefin molecule is increased, and meanwhile, when the volatile organic compound in polypropylene is acted, the polyolefin porous material with smaller pore size avoids the space wall effect caused by the accumulation of the volatile organic compound in the polypropylene.
The method of compounding the polyolefin porous material and the liquid extractant of the present application can be selected conventionally by those skilled in the art.
In a second aspect, the invention provides a method for using the deodorizing master batch loaded with liquid extractant, comprising: and mixing and drying the polypropylene, the toughening agent and the deodorizing master batch, and then placing the mixture in a double-screw extruder for melting, extruding, cooling and granulating to obtain the modified polypropylene.
Preferably, the main machine rotating speed of the double-screw extruder is 300-350 revolutions per minute, and more preferably 320 revolutions per minute.
Preferably, the twin screw extruder has an aspect ratio of 40.
Preferably, the screw diameter of the twin-screw extruder is 35-40mm, preferably 38mm.
In order to improve the processing efficiency, the applicant sets the screw diameter of the twin-screw extruder to 35-40mm in experiments, however, the applicant found that the processing efficiency is improved at this time, but the odor removing effect is reduced due to the excessively large extrusion amount in the extrusion process, and through a series of experimental researches and a series of thinking, the applicant unexpectedly found that when the host rotation speed is 300-350 rpm, the excellent VOC removing rate can be maintained at the time when the screw diameter is relatively large, and the applicant considers that the possible reason is that the liquid extractant can be fully contacted with the volatile organic matters at the specific rotation speed, and the action force between the extractant molecules and the volatile organic matters due to the external force of the relatively large molecular weight is avoided while the liquid extractant molecules and the volatile organic matters interact with each other.
In one embodiment, the method of using the liquid extractant-loaded deodorizing masterbatch comprises: the polypropylene, the toughening agent and the deodorizing master batch are mixed and dried and then are placed in a double-screw extruder, the diameter of the screw of the extruder is 38mm, the length-diameter ratio L/D is 40, the vacuum degree is not lower than 0.8MPa, and the temperature of each partition from a feed inlet to a machine head outlet of the machine barrel is as follows: 55 ℃, 160 ℃, 190 ℃, 200 ℃, 205 ℃, 210 ℃ and 200 ℃ are subjected to melting, extrusion, cooling, granulation and drying treatment, thus obtaining the composite material.
The types of polypropylene and toughening agent according to the present application are not particularly limited, and those skilled in the art may make routine selections.
In the use process of the deodorizing master batch, a recovery device can be added.
Compared with the prior art, the invention has the following beneficial effects:
According to the application, by adding the specific liquid extractant, namely selecting the specific azeotrope with good compatibility with volatile matters and matching with the vacuumizing device, volatile organic compounds in the modified polypropylene can be carried away from the polymer in the extrusion process, the content of the volatile organic compounds is reduced, meanwhile, bad smell is reduced, and meanwhile, the modified polypropylene has excellent physical properties.
