Description
Technical Field
The invention relates to the technical field of foaming materials, in particular to a foaming cross-linked thermoplastic elastomer material and application thereof.
Background
The foaming material is widely applied to the fields of shoe wear and yoga mats, and is prepared by chemical foaming or reaction foaming; chemical foaming has the problems of foaming agent residue, foaming agent decomposition, high product toxicity and the like, and reactive foaming has the problems of incomplete reaction, monomer residue, large smell and the like.
Chinese patent CN114989570a discloses a method for preparing a crosslinked thermoplastic elastomer micro-foaming coiled material, which uses supercritical nitrogen fluid to impregnate and irradiate the crosslinked thermoplastic elastomer coiled material, and uses low-temperature air locking treatment and hot air material haircutting to foam the crosslinked thermoplastic elastomer micro-foaming coiled material. However, the strength of the foaming material disclosed in the above patent is low, and it is difficult to meet the increasing requirements of users.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a foaming cross-linked thermoplastic elastomer material with excellent mechanical properties and application thereof.
In order to achieve the above purpose, the technical scheme adopted by the invention is as follows:
a foamed crosslinked thermoplastic elastomer material comprising the following components in parts by weight: 100 parts of thermoplastic elastomer resin and 1-18 parts of plasticizing rubber; the melting point of the thermoplastic elastomer resin is 40-120 ℃; the plasticizing rubber comprises at least one of natural rubber, chloroprene rubber, styrene butadiene rubber and styrene rubber.
For thermoplastic elastomer resin with lower melting point, the resin is unfavorable for foaming when the crosslinking is higher, and the strength of the resin is low when the crosslinking degree is lower, so that the prepared foamed product has low strength and poor mechanical property.
The plasticized rubber has large molecular weight and high torque of processing equipment, and when the content of the plasticized rubber in the formula is too high, the processability of the formula is poor, and the components in the formula are difficult to uniformly mix; when the content of the plasticized rubber in the formula is too low, the improvement effect of the plasticized rubber on the formula performance is not obvious.
Preferably, the weight part of the plasticized rubber is 3 to 15 parts. Controlling the weight portion of the plasticizing rubber in the range further improves the comprehensive performance of the plasticizing rubber.
Preferably, the foaming cross-linked thermoplastic elastomer material also contains 0-20 parts of auxiliary agent, wherein the auxiliary agent comprises at least one of nucleating agent, pigment, lubricant and antioxidant.
Preferably, the thermoplastic elastomer resin is at least one of a polyolefin elastomer and a styrene elastomer. Compared with other thermoplastic elastomer resins, the foaming cross-linked thermoplastic elastomer material prepared from the thermoplastic elastomer resin has better mechanical property and better uniformity of products.
Preferably, the gel content in the foamed crosslinked thermoplastic elastomer material is 45wt.% to 75wt.%. The gel content is too high, the growth of cells is hindered, the molecular chain mobility is weak, a moderate expansion rate is difficult to obtain, and the density of the prepared product is high; the gel content is too low, the molecular chain movement is intense, the fluid viscosity is small, and the foaming material can shrink obviously, so that the stability of the processing process is affected. The gel content is related to the properties of the foamed crosslinked thermoplastic elastomer material, and for a foamed material of the same or similar density, the higher the gel content, the higher the tensile strength of the foamed material, however, the higher the gel content, the lower the toughness of the foamed material, and the elongation at break.
The foaming cross-linked thermoplastic elastomer material can be prepared by referring to CN114989570A, and specifically comprises the following steps:
(1) Adding the components into a double-screw extrusion casting machine according to the proportion, extruding and casting to form a film, and performing irradiation crosslinking to obtain a crosslinked thermoplastic elastomer coiled material;
(2) And immersing the crosslinked thermoplastic elastomer coiled material in supercritical nitrogen fluid to obtain an immersed crosslinked thermoplastic elastomer coiled material, and then locking air at low temperature and introducing hot air to perform physical foaming crosslinking to obtain the foaming crosslinked thermoplastic elastomer material.
Meanwhile, the invention also discloses a foaming cross-linked thermoplastic elastomer/cloth composite coiled material, wherein the foaming cross-linked thermoplastic elastomer comprises the following components in parts by weight: 100 parts of thermoplastic elastomer resin, 1-18 parts of plasticizing rubber and 0-20 parts of auxiliary agent, wherein the auxiliary agent comprises at least one of nucleating agent, pigment, lubricant and antioxidant.
The preparation method of the foaming cross-linked thermoplastic elastomer/cloth composite coiled material comprises the following steps:
(1) Weighing the thermoplastic elastomer resin, the plasticizing rubber and the auxiliary agent according to a proportion, drying, uniformly mixing, extruding by a double-screw extrusion casting machine, drawing by a pair of rollers, cooling, and performing irradiation crosslinking to obtain a crosslinked thermoplastic elastomer coiled material;
(2) Immersing the cross-linked thermoplastic elastomer coiled material in supercritical nitrogen fluid, releasing pressure by a high-pressure container, taking out the immersed coiled material, and performing gas locking treatment to obtain an immersed cross-linked thermoplastic elastomer coiled material;
(3) Foaming the impregnated crosslinked thermoplastic elastomer coiled material to obtain a foamed crosslinked thermoplastic elastomer coiled material, maintaining the foaming temperature unchanged, drawing the foamed crosslinked thermoplastic elastomer coiled material in an expanded state by adopting a tension roller, hot-pressing and compounding the foamed crosslinked thermoplastic elastomer coiled material with cloth by adopting a compound roller, cooling, correcting and rolling to obtain the foamed crosslinked thermoplastic elastomer/cloth compound coiled material.
The foamed crosslinked thermoplastic elastomer/cloth composite coiled material prepared by the method has higher peel strength between the foamed crosslinked thermoplastic elastomer and cloth.
Preferably, in step (1), the thickness of the crosslinked thermoplastic elastomer web is 1 to 6mm. Further preferably, the thickness of the crosslinked thermoplastic elastomer web is 2 to 5mm. Controlling the thickness of the cross-linked thermoplastic elastomer coiled material within the above range is beneficial to improving the stability of the processing process and ensuring the product to have higher uniformity.
Preferably, in step (3), the foaming temperature is 100 to 180 ℃, and more preferably, the foaming temperature is 120 to 170 ℃. When the stretching and rolling are carried out at the above temperature, the bonding degree of the foamed thermoplastic elastomer and the cloth is high, and the thickness of the prepared coiled material is uniform, and no air bubbles are generated.
Preferably, in the step (3), the thickness compression amount of the material at the composite roller is 10-30% of the original thickness, and the temperature of the composite roller is 160-190 ℃. The process is favorable for improving the peeling strength between the foaming cross-linked thermoplastic elastomer and the cloth, does not cause great attenuation of the elasticity of the material, and can prolong the service life of the composite coiled material.
In addition, the invention also discloses application of the composite coiled material in the fields of shoe wear and yoga mats.
Compared with the prior art, the invention has the beneficial effects that:
The invention overcomes the technical difficulty that the low-melting-point thermoplastic elastomer is difficult to prepare the foaming material with higher strength by selecting the components and the dosage of each component of the foaming cross-linking thermoplastic elastomer material, and simultaneously further improves the strength and uniformity of the material by limiting the gel content of the foaming cross-linking thermoplastic elastomer material.
