Abstract
The invention discloses a modified rectorite/natural latex composite foaming material and a preparation method thereof, wherein the preparation raw materials comprise: natural latex, carboxylic acrylonitrile butadiene latex, modified rectorite, vulcanizing agent, accelerator and anti-aging agent; a method of modifying modified rectorite comprising: adding water into an organic modifier to obtain an organic modifier solution; adding water to rectorite to obtain a rectorite solution; adding the rectorite solution into the organic modifier solution dropwise to obtain a modified rectorite precursor solution; carrying out hydrothermal reaction on the modified rectorite precursor solution to obtain a modified rectorite precursor; sintering the modified rectorite precursor to obtain the modified rectorite. Compared with the conventional natural rubber foaming material, the mechanical property and the corrosion resistance of the modified rectorite/natural latex composite foaming material prepared by the invention are greatly improved.
Description
Technical Field
The invention relates to the technical field of high molecular compound compositions, in particular to a modified rectorite/natural latex composite foaming material and a preparation method thereof.
Background
Natural rubber has the advantages of good flexibility, good elasticity, high comfort and the like as a sole material, and has the defect of poor wear resistance, so that the mechanical property enhancement treatment needs to be carried out on the natural rubber sole material.
Currently, methods for reinforcing natural rubber materials include, but are not limited to: (one) filler reinforcement: preparation and properties of clay/natural rubber nanocomposites [ J ] synthetic rubber industry, 2015, 28 (2): 135-139; preparation and properties of carbon nanotube/natural rubber composite [ J ] composite science, 2005, 22 (5): 72-77; preparation and performance of reduced graphene oxide/natural rubber-nitrile rubber composite [ J ] composite academic newspaper, 2018, 5 (5): 1253-1259; (II) polymer blending reinforcement: preparing polylactic acid/natural rubber porous material [ J ] plastic by microcellular foaming, wherein the ratio of the polylactic acid/natural rubber porous material [ J ] plastic to the polylactic acid/natural rubber porous material [ 2018, 47(2) is as follows: 50-53; application of natural rubber/trans-butyl-pentyl rubber blend in tread rubber of all-steel radial tires [ J ] polymer material science and engineering, 2018, 34 (9): 89-95. Because natural rubber has poor polarity, and most of reinforcing materials are polar materials, all the reinforcing treatment methods need to solve the following problems: the mechanical strength of the natural rubber is improved, and the problem of compatibility of the reinforcing material and the natural rubber is solved.
The carboxylic butyronitrile latex is anionic high molecular polymer emulsion, and has good oil resistance, corrosion resistance and mechanical property. And because carboxyl with strong polarity is introduced into the macromolecular chain of the carboxylated nitrile latex, the activity and the bonding strength are improved, and the mechanical strength and the polarity of the natural latex can be improved by blending the carboxylated nitrile latex with the natural latex, so that the compatibility with a reinforcing material is improved.
Rectorite is a 1:1 regular interlayer mineral composed of dioctahedral mica and dioctahedral smectite, has the properties of good high temperature resistance, plasticity, dispersibility, expansibility, adsorbability, hydration property, cation exchange property, colloid double-layer, electromotive potential and the like, has good affinity with a polymer, and can be used as a reinforcing material to improve the mechanical property of the polymer. However, in particular, the compatibility problem of the rectorite reinforced natural rubber material and the rubber needs to be solved, and the uniformity of the rectorite material in the polymer is improved, so that the reinforcing effect is improved. Therefore, a modification treatment of the rectorite material is required. At present, rectorite modified latex foaming materials are rarely used for manufacturing sole materials.
Chinese patent CN201410361107.9 discloses a method for preparing a rubber/clay composite material with thermal-oxidative aging resistance, which comprises the steps of adding catecholamine monomers into clay water suspension subjected to ultrasonic stripping pretreatment under the condition of aerobic and alkaline at room temperature, and performing self-polymerization deposition on the surface of a clay sheet layer; then compounding with a rubber matrix in an emulsion blending mode, flocculating, washing, drying, mixing and vulcanizing to obtain the rubber/clay nano composite material. However, the clay aqueous suspension is directly blended and modified with a rubber latex material, the mixing uniformity is greatly influenced by contingency, the product property is unstable, and the prepared rubber composite material mainly improves the anti-aging performance of rubber and has limited improvement on the mechanical performance of the rubber.
Chinese patent CN201611120022.7 discloses a graphene natural rubber composite material for conveyor belt cover rubber and a preparation method thereof, wherein the graphene natural rubber composite material is prepared by taking graphene, phyllosilicate, white carbon black and natural latex as raw materials and adopting a wet mixing technology; plasticating the graphene natural rubber composite material, sequentially adding zinc oxide, stearic acid, an anti-aging agent, a silane coupling agent, a reinforcing agent and aromatic oil, and then mixing for the first time; then adding sulfur and an accelerant and mixing for the second time to obtain the product. However, this patent does not improve the compatibility of the reinforcing material with natural latex materials and has limited improvement in mechanical properties.
Therefore, in view of the above problems, there is a need to provide a reinforcing treatment method capable of effectively improving the mechanical strength of natural rubber materials, and simultaneously solving the compatibility problem between natural latex materials and reinforcing materials, so that the prepared natural latex composite material has good performance in the field of sole materials.
Disclosure of Invention
