Definitions
- the present invention relates to a polymer product having a cushioning property, a composite product, and a method for producing the same.
- the armrest of the door trim which is a vehicle interior product to which the elbow of the occupant abuts, is often configured as a composite product by combining a first member that maintains the product shape and a second member that imparts a soft feeling. ..
- Patent Document 1 describes the following armrests (1) to (4), which have different forms of imparting a soft feeling to the second member, as an example of such a composite product.
- a second member obtained by wrapping a polyurethane foam with a thin-walled skin made of an olefin-based thermoplastic elastomer (TPO) is adhered to the outer surface of a first member (molded base material) made of polypropylene (PP).
- TPO thermoplastic elastomer
- PP polypropylene
- TPO is a resin material in which the mixing ratio of rubber (EPDM) and oil (liquid paraffin, etc.) is higher than that of PP, etc., thereby giving a soft feeling to the outer surface portion composed of the second member.
- the outer surface of the first PP member is integrally provided with a second member composed of a TPO skin and a large number of pin-shaped or rib-shaped protrusions protruding from the back surface thereof, and the skin is locked.
- Wearing type armrest (Fig. 13 of the same document). It is explained that the bending deformation of the protrusion gives elasticity, which gives a soft feeling to the outer surface of the member composed of the skin.
- the type (1) above has problems such as high material cost and easy deterioration due to heat and hydrolysis because a foam made of polyurethane is used for the second member. Therefore, the types (2) to (4) above, which use a thermoplastic elastomer having less of these problems as the second member, have come to be preferred, and the type (4) has been increasing in particular.
- Patent Document 2 describes that in the type (4) above, the second member is formed of TPO, polyvinyl chloride (PVC), polyurethane-based thermoplastic elastomer (TPU), or the like.
- Patent Document 3 describes that in the type (4) above, the second member is formed of a soft PVC, TPO, a styrene-based thermoplastic elastomer (TPS), or a polyester-based thermoplastic elastomer (TPEE).
- TPS styrene-based thermoplastic elastomer
- TPEE polyester-based thermoplastic elastomer
- the present inventors comprehensively examined the tactile sensation of the same type, there was a place that was inferior to the tactile sensation of the above type (1) using a polyurethane foam. That is, the polyurethane foam has a relatively high resilience, and its high resilience feel is familiar to the user, whereas the one using a thermoplastic elastomer has a relatively low resilience. Therefore, it is a place where the tactile sensation is not tense.
- an object of the present invention is to provide a composite product capable of obtaining a highly repulsive good feel by using a thermoplastic elastomer.
- Polymer products In polymer products that are given cushioning properties by elastic deformation of polymer products.
- Polymer products are made of solid (non-foaming) or slightly foamed thermoplastic elastomers with a foaming ratio of 1.1 times or less, with a modulus of impact resilience at 23 ° C. measured in accordance with JIS K6255 at 23 ° C. Is formed and It is characterized in that the hysteresis loss rate at 23 ° C. measured by compressing and decompressing the polymer product at a speed of 60 mm / min is 28% or less.
- Composite product A first member and a second member including a plate-shaped portion and a second member including a plurality of protrusions protruding from the back surface thereof and having a protrusion abutting on the first member, and cushioning property due to elastic deformation of the second member.
- a plate-like part and a plurality of protrusions are formed by a solid or slightly foamed thermoplastic elastomer having a elastic modulus at 23 ° C. measured according to JIS K6255 at 23 ° C. and a foaming ratio of 1.1 times or less. Is formed integrally, It is characterized in that the hysteresis loss rate at 23 ° C. measured by compressing and decompressing the composite product at a speed of 60 mm / min is 28% or less.
- the load when the displacement is 1 mm is 2 to 12 N at the time of the compression by the indenter having the spherical radius of the tip of 10 mm. This is because an appropriate soft feeling can be obtained.
- Method for manufacturing a polymer product In a method for manufacturing a polymer product in which cushioning property is imparted by elastic deformation of the polymer product.
- a slightly foamed thermoplastic elastomer having a rebound elastic modulus of 30 to 90% at 23 ° C. and a foaming ratio of 1.1 times or less measured according to JIS K6255 is injected into the mold, and the speed is 60 mm. It is characterized by molding a polymer product having a hysteresis loss rate of 28% or less at 23 ° C. measured by compression and decompression at / min.
- Method for manufacturing a composite product A first member and a second member including a plurality of protrusions protruding from a plate-shaped portion and its back surface and having a protrusion abutting on the first member are included, and the second member is elastically deformed.
- a plate-shaped plastic elastomer with a rebound resilience at 23 ° C. measured in accordance with JIS K6255 at 23 ° C. and a solid or slightly foamed thermoplastic elastomer having a foaming ratio of 1.1 times or less is injected into the mold.
- the part and multiple protrusions are integrally molded, It is characterized in that the hysteresis loss rate at 23 ° C. measured by compressing and decompressing the composite product at a speed of 60 mm / min is 28% or less.
- the plate-like portion and the plurality of protrusions of the second member of the polymer product or composite product are made of a solid or slightly foamed thermoplastic elastomer having a rebound resilience of 30 to 90% and a foaming ratio of 1.1 times or less. Since it is formed and the hysteresis loss rate of the polymer product or composite product is 28% or less, it gives a good feeling of high resilience. When the hysteresis loss rate exceeds 28%, the protrusions remain crushed due to creep deformation due to heat, and the tactile sensation deteriorates to a less tense one, which makes it feel cheap.
- the lower limit of the hysteresis loss rate is not particularly limited and is determined by the limit value of the material, but if it is dared, it is 1%.
- thermoplastic elastomer can be used to obtain a highly repulsive feel.

- FIG. 5 is a graph showing the load-displacement curves of Comparative Examples 1 and 2.
- the first member is not particularly limited, and examples thereof include a member directly under the surface layer portion and a base material in the composite product.
- the material of the first member is not particularly limited, but is preferably one having a higher hardness than the material of the second member in order to maintain the shape of the product, and various resins, metals, wood, ceramics and the like can be exemplified.
