Abstract
The invention discloses a high fatigue resistance air fiber mat and a preparation method thereof, wherein the high fatigue resistance air fiber mat comprises 60-90 parts of thermoplastic elastomer resin, 10-40 parts of polyolefin resin, 1-2 parts of cross-linking agent, 0.1-0.4 part of initiator, 0.1-0.5 part of catalyst, 0.3-0.6 part of antioxidant and 0.5-2 parts of processing aid; adding thermoplastic elastomer resin, polyolefin resin, a cross-linking agent, an initiator, a catalyst and an antioxidant into an extruder, melting to form fluid, extruding the fluid through a die head to form fiber filaments, winding and bonding the fiber filaments under the buoyancy effect when the fiber filaments fall to the water surface, and performing water cooling shaping to obtain the high fatigue-resistant air fiber mat. Compared with the conventional air fiber pad, the high-fatigue-resistance air fiber pad prepared by the invention has the advantages of better high elasticity, high permeability, high support, high fatigue resistance and the like, is suitable for manufacturing mattresses or automobile cushions, sleeping mats and the like with higher use frequency, and has simple preparation method and easy production, popularization and application.
Description
Technical Field
The invention belongs to the technical field of high polymer materials, and particularly relates to a high fatigue-resistant air fiber mat and a preparation method thereof.
Background
The main material types of the mattress or cushion commonly used at present are sponge, spring, latex and the like. The resilience of the sponge is poor, so that the sponge cushion is easy to dent; the spring pad with enough support degree lacks softness, and has quicker loss after long-term use, so that the surface is uneven; the cost of the latex pad is high and the latex pad is easy to cause allergy to human body. The high polymer fiber pad is a high polymer material which is heated and melted, after spinning plate spinning, fiber filaments are wound to form bonding points, and the bonding points are gathered to form a three-dimensional ring connector with irregular holes. Chinese patent (publication No. CN 113287902A) discloses a preparation method of an air fiber cushion, which uses polyolefin elastomer as a base polymer and is matched with proper additives, and the air fiber cushion with high elasticity, high support and good air permeability is obtained through the steps of mixing, stirring, heating and melting, extruding filaments, cooling, shaping, flattening, cutting and the like.
However, large-area collapse often occurs in the use process of the common fiber mat, the supporting hardness and rebound effect are seriously deteriorated, and the service life of the common fiber mat is greatly shortened; the bond points between the filaments were analyzed as critical stress sites, which resulted in increased collapse stiffness loss (after compression fatigue) of the fiber mat once debonded and destroyed. Therefore, how to increase the number of bonding points and the bonding strength becomes a key problem in preparing a high fatigue resistant fiber mat.

performance testing
The air fiber mats prepared in examples 1 to 5 and comparative examples 1 to 3 were tested for tensile strength, elongation at break, 25% indentation hardness, indentation ratio, and compressive fatigue hardness loss, wherein the indentation ratio is the ratio of 65% to 25% deformation corresponding values when the fiber mats were subjected to an open indentation hardness test; compression fatigue hardness loss: the fiber mat was repeatedly compressed about one hundred thousand times, and the difference in the corresponding collapse hardness at 40% of the compressed fiber mat thickness was measured, with the compression frequency (70.+ -. 5) times/min. The test results are shown in table 1 below:
table 1 results of air fiber mat performance tests prepared in examples 1 to 5 and comparative examples 1 to 3
As can be seen from table 1, the addition of the crosslinking agent can crosslink the air fiber mat in the shaping process in water, thereby improving the tensile strength and 25% indentation hardness and greatly reducing the compression fatigue hardness loss; however, the elongation at break is reduced due to the presence of more micro network structures after crosslinking; there is no obvious trend in the variation of the collapse ratio. From the results of examples 1 and 3, it can be seen that the more the crosslinking agent is added, the better the crosslinking agent is, the more the amount of the crosslinking agent is added, the more the corresponding initiator is needed, the initiator is peroxide, which is easy to degrade the polymer material in the melting process, so that the material performance is reduced, the compression fatigue hardness loss is higher, and the more the crosslinking agent is, the more the odor is present, and the greater the odor is present in the air fiber mat under the condition of the more the amount of the crosslinking agent is added, so that the user experience is affected.
The addition of the cross-linking agent is favorable for forming a cross-linking structure by the polyolefin resin, improves the tearing strength of the bonding part of the fiber yarn, and improves various performance indexes such as wear resistance, heat resistance, bending resistance and the like of the fiber yarn due to the fact that the fiber yarn which does not form the bonding structure also has more micro-cross-linking structures.
