It should be understood that the inorganic particles may be dispersed in the polyolefin emulsion system in such a manner as to be coated with the polyolefin resin and form colloidal particles of core-shell structure, so as to be stably and uniformly dispersed in the polyolefin emulsion system, so as to enable the performance of the inorganic particles in the polyolefin emulsion to be fully exerted; depending on the choice of the type of inorganic particles, different inorganic particles may impart different properties to the polyolefin emulsion, for example, when the inorganic particles are alumina or silica, the heat resistance and shape retention properties of the emulsion particles are improved, and the overall properties of the polyolefin emulsion are also improved.
In addition, the inorganic particles are coated by the polyolefin resin to form emulsion particles with a core-shell structure, the core-shell structure has higher stability, the inorganic particles serving as the inner cores are blocked by the polyolefin resin of the outer shell in a plurality of emulsion particles in an emulsion system, the inorganic particles are not easy to agglomerate in the polyolefin emulsion, and the emulsion particles can be stably and uniformly dispersed in the polyolefin emulsion; and the inorganic particles are used as the inner cores of the emulsion particles, so that the density of the emulsion particles can be adjusted, the emulsion particles are prevented from floating and agglomerating in the polyolefin emulsion, the stability of the polyolefin emulsion is improved, and the long-term storage of the polyolefin emulsion is facilitated.
In some embodiments of the present application, the polyolefin emulsion is prepared from the following raw materials in parts by weight: polyolefin resin: 5-40 parts of a lubricant; inorganic particles: 0.005-20 parts; solvent: 10-40 parts of a lubricant; deionized water: 90-110 parts; emulsifying agent: 0.1-5 parts.
It can be understood that by designing the proportion of the components, 5-40 parts of polyolefin resin is mainly used for forming the shell of the emulsion particle, 0.005-20 parts of inorganic particles are mainly used for forming the inner core of the emulsion particle, 10-40 parts of solvent can dissolve and waterborne the polyolefin resin in the preparation process, the inorganic particles are uniformly dispersed in the polyolefin resin and coated by the polyolefin resin to form the emulsion particle with a stable core-shell structure, 90-110 parts of deionized water is used as a continuous phase of the polyolefin emulsion for dispersing the emulsion particle, and 0.1-5 parts of emulsifier plays a role of reducing interfacial tension in the emulsion, so that incompatible components are uniformly dispersed together to form the stable polyolefin emulsion; through the synergistic effect of the components, the prepared polyolefin emulsion can form emulsion particles with inorganic particles as an inner core and polyolefin resin as an outer shell and in a core-shell structure, so that the dispersibility and stability of the inorganic particles in the polyolefin emulsion are obviously improved, the performance of the inorganic particles in the polyolefin emulsion can be fully exerted, and the overall performance of the polyolefin emulsion is further improved.
It is clear that in the preparation raw materials of the polyolefin emulsion of the embodiment of the application, the polyolefin resin can be 5 parts, 10 parts, 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts or any weight part range in 5-40 parts by weight; the inorganic particles may be 0.005 parts, 0.105 parts, 2.205 parts, 4.605 parts, 8.805 parts, 10.005 parts, 11.105 parts, 12.205 parts, 14.605 parts, 18.805 parts, 20 parts, or any part by weight within 0.005-20 parts or any range of parts by weight; the solvent can be 10 parts, 15 parts, 20 parts, 25 parts, 30 parts, 35 parts, 40 parts or any part range of the weight in 10-40 parts; the deionized water can be 90 parts, 91 parts, 92 parts, 93 parts, 94 parts, 95 parts, 96 parts, 97 parts, 98 parts, 99 parts, 100 parts or any weight part range within 90-100 parts; the emulsifier may be 0.1 part, 1.1 part, 2.3 parts, 3.4 parts, 4.5 parts, 5 parts, or any part by weight or any range of parts by weight within 0.1 to 5 parts.
To improve the softening point of the polyolefin emulsion, in some embodiments, the polyolefin emulsion is prepared from a raw material that further includes not more than 20 parts by weight of a tackifying resin. By designing not more than 20 parts by weight of tackifying resin in the preparation raw materials of the polyolefin emulsion, the combined action of the tackifying resin and the polyolefin resin can improve the softening point of the latex particle shell resin, thereby improving the softening point of the polyolefin emulsion and further improving the overall performance of the polyolefin emulsion.
The tackifying resin may be 0 part by weight, or may be 0.01 part by weight, 1 part by weight, 2 parts by weight, 3 parts by weight, 4 parts by weight, 5 parts by weight, 6 parts by weight, 7 parts by weight, 8 parts by weight, 9 parts by weight, 10 parts by weight, 11 parts by weight, 12 parts by weight, 13 parts by weight, 14 parts by weight, 15 parts by weight, 16 parts by weight, 17 parts by weight, 18 parts by weight, 19 parts by weight, 20 parts by weight, or any weight range of 0to 20 parts by weight, depending on the application requirements of the polyolefin emulsion.
In an alternative embodiment of the application, the D50 particle size of the emulsion particle is 0.01-20 μm, preferably 0.05-10 μm; by designing the average particle diameter D50 of the emulsion particles to be within the particle diameter range, the stability and the dispersibility of the emulsion particles in the polyolefin emulsion can be improved, so that the performance of inorganic particles can be brought into play, and the overall performance of the polyolefin emulsion can be effectively improved.
In an alternative embodiment of the present application, the particle size of the inorganic particles D50 is 0.01 to 10 μm, preferably 0.05 to 5 μm, and the inorganic particles have a smaller particle size, and the smaller size inorganic particles can provide a larger specific surface area, so that the inorganic particles are more easily coated with the polyolefin resin, and a latex particle with a stable core-shell structure is formed in the emulsion system along with the polyolefin resin.
In an alternative embodiment of the application, the softening point of the polyolefin resin is 50-180 ℃, preferably 60-160 ℃; the polyolefin resin with the softening point in the range is easier to be heated and dissolved in the preparation process so as to promote the coating of inorganic particles and form a stable shell layer outside the inorganic particles.
In an alternative embodiment of the present application, the melting point of the inorganic particles is higher than the softening point of the polyolefin resin, so that the inorganic particles can still maintain the complete particle form after the polyolefin resin is heated and dissolved, and thus the inorganic particles are coated by the polyolefin resin in the emulsion system to form stable emulsion particles.
In some embodiments of the present application, the solvent includes a hydrophilic solvent and a hydrophobic solvent, the hydrophilic solvent can promote the hydration of the polyolefin resin, improve the compatibility of the polyolefin resin with deionized water in the system, and promote the stability of the polyolefin resin dispersed in the system to form a stable dispersion system, and the hydrophilic solvent is also beneficial to reducing the attractive force between latex particles and inhibiting the agglomeration trend thereof, so as to maintain the smaller size of the latex particles, so that the performance of the inorganic particles is effectively exerted; and the interaction force exists between the hydrophobic solvent and polyolefin resin molecules, so that the solvent molecules can permeate into the molecular structure of the polyolefin resin and interact with the polyolefin resin, thereby promoting the further dissolution of the resin; hydrophilic solvent and hydrophobic solvent are used as solvents to facilitate the polyolefin resin to be fully dissolved and then coated on the surfaces of inorganic particles, so that the emulsion particles with higher stability are formed.
In some embodiments of the present application, the mass ratio of the hydrophilic solvent to the hydrophobic solvent is (0.5-2): 1, in the mass ratio range, the hydrophilic solvent and the hydrophobic solvent can effectively play respective roles, so that the polyolefin resin is fully coated on the surfaces of the inorganic particles, and emulsion particles with core-shell structures with higher stability can be formed in the polyolefin emulsion.
In some embodiments of the present application, the inorganic particles include coated modified inorganic particles and/or uncoated modified inorganic particles, for example, the inorganic particles may be surface coated modified silica or titania, etc., and the inorganic particles may be surface coated unmodified alumina or boehmite, etc.
In some embodiments of the present application, the emulsifier may be an anionic emulsifier, a nonionic emulsifier, or a mixed emulsifier of an anionic emulsifier and a nonionic emulsifier. It is understood that anionic emulsifiers interact with the oil-water interface mainly through negatively charged hydrophilic groups to form stable polyolefin emulsions; the nonionic emulsifier mainly reduces the tension of an oil-water interface through the interaction of hydrophobic groups and an oil phase, so that the emulsification process is promoted; both can promote the emulsification reaction of the system in the preparation process so as to be beneficial to forming polyolefin emulsion, and can form emulsion particles with core-shell structure with higher stability in the polyolefin emulsion.
In some embodiments of the present application, when the emulsifier is a mixed emulsifier of an anionic emulsifier and a nonionic emulsifier, the mass ratio of the anionic emulsifier to the nonionic emulsifier is 1: (0.01-2) to effectively promote the emulsification reaction of the system in the preparation process so as to promote the formation of the polyolefin emulsion and enable the inside of the polyolefin emulsion to form emulsion particles with core-shell structures with higher stability.
In some embodiments of the present application, the polyolefin resin includes at least one of a polypropylene resin, an amorphous α -olefin copolymer resin, an ethylene-octene or ethylene-butene copolymer resin, an ethylene-vinyl acetate copolymer resin, an ethylene-acrylic acid (ester) copolymer resin, a maleic anhydride grafted polyolefin resin, an acrylic acid grafted polyolefin resin, a methacrylic acid grafted polyolefin resin, and an acrylic acid/methacrylic acid blend modified polyolefin resin, which may each serve as a shell in a polyolefin emulsion as the polyolefin resin, coating inorganic particles to form latex particles having a stable core-shell structure in the polyolefin emulsion.
In some embodiments of the application, the inorganic particles comprise at least one of alumina, boehmite, silica, zinc oxide, and titania; the substances can be coated by polyolefin resin as inorganic particles, so that emulsion particles with a core-shell structure with higher stability are formed in polyolefin emulsion; in addition, the inorganic particles of the substances can adjust the density of the latex particles, and avoid the phenomenon that the latex particles in the polyolefin emulsion float upwards and agglomerate, so that the overall performance of the polyolefin emulsion can be effectively improved.

The following is a description of the advantages of the polyolefin emulsion prepared according to the embodiments of the present application with reference to fig. 1 to 7, table 2 and table 3.
Compared with comparative example 1, as shown in fig. 1, the polyolefin emulsion prepared in example 1 has latex particles dispersed therein, and further referring to fig. 2 and 3, the latex particles in the polyolefin emulsion have a core-shell structure, the polyolefin resin forms a complete and stable coating layer on the surface of inorganic particles, and the dispersion of the latex particles is good and the particle size is uniform; referring to fig. 4 and 5, the polyolefin emulsion prepared in comparative example 1 has latex particles dispersed therein, and the latex particles of the polyolefin emulsion prepared in comparative example 1 have no core-shell structure since inorganic particles are not added to the preparation raw material. With further reference to fig. 6 and 7, the integrity of the latex particles in the polyolefin emulsion prepared in example 1 is better, and the deformation of the latex particles is serious and a large amount of the latex particles are bonded after the polyolefin emulsion prepared in comparative example 1 is hot pressed, which indicates that the stability and heat resistance of the polyolefin emulsion in example 1 are better, because the latex particles of the polyolefin emulsion in example 1 have a stable core-shell structure, and the latex particles take Al 2O3 particles as the inner core and ethylene-ethyl acrylate copolymer resin as the outer shell, and the Al 2O3 particles as the inner core can improve the heat resistance and shape retention of the latex particles, so that the overall performance of the polyolefin emulsion is effectively improved.
With further reference to tables 2 and 3, the samples coated with the polyolefin emulsion prepared in example 1 had a permeability of 203.8 s/100cc when left at 80℃for 1min, which is similar to the permeability of the samples coated with the polyolefin emulsion prepared in comparative example 1 at 80 ℃; and when the sample is placed at 120 ℃ for 20min, the air permeability of the sample obtained by coating the polyolefin emulsion prepared in the example 1 at 120 ℃ is 376 s/100cc, and compared with the air permeability of the sample obtained by coating the polyolefin emulsion prepared in the comparative example 1 at 120 ℃ is obviously improved; the samples coated by the polyolefin emulsion prepared in the embodiment 1 have better air permeability at a high temperature of 120 ℃, because the polyolefin emulsion in the embodiment 1 has emulsion particles with a core-shell structure, al 2O3 particles have higher stability and dispersibility in the polyolefin emulsion, the heat resistance and shape retention capability of Al 2O3 particles on the emulsion particles can be fully exerted, the emulsion particles can be spherically distributed on the samples at 80 ℃ and 120 ℃, the porous base materials on the samples are less blocked, and the samples have better air permeability; in comparative example 1, the polyolefin emulsion is not introduced with inorganic particles, the latex particles have no core-shell structure, the latex particles have poor heat resistance and stability, and particularly, serious deformation collapse is easy to occur under the high temperature condition of 120 ℃, so that the porous substrate of the sample is seriously blocked, and the sample has poor air permeability.
With continued reference to Table 3, the emulsion of example 1 had a skin mass of 0.3g, which was significantly lower than that of comparative example 1, because the Al 2O3 particles within the latex particles in example 1 were able to adjust the latex particle density so that the latex particles did not easily float up in the polyolefin emulsion; in contrast to comparative examples 1 to 3 (in particular comparative example 1), the latex particles do not have a core-shell structure because the inorganic particles are not coated, and the latex particles are easy to float and agglomerate, so that the emulsion crust quality is higher, and the polyolefin emulsion is not easy to store.
In summary, according to the embodiment of the application, the emulsion particle with the inorganic particle as the inner core and the polyolefin resin as the outer shell and the high-stability core-shell structure is formed by the compatibility of the raw materials such as the polyolefin resin, the inorganic particle, the solvent and the emulsifier, so that the dispersibility and the stability of the inorganic particle in the polyolefin emulsion are obviously improved, the performance of the inorganic particle in the polyolefin emulsion is fully exerted, and the overall performance of the polyolefin emulsion is further improved.
