乏しく、摩耗に対しても弱いという致命的な欠陥
がある。 On the other hand, there are reinforcing core metal plates whose bending stress is strengthened by steps and coated with vinyl chloride resin, but this produces sink marks on the surface corresponding to the steps and is flat with no unevenness. It has the drawback of spoiling the aesthetic appearance due to the formation of a surface, and also has the fatal flaw that it lacks a soft feel and is susceptible to abrasion.

すいという問題がある。 Therefore, attempts have been made to reduce the weight by using vinyl chloride foam for the coating layer, but the creep is greater than the heat resistance inherent to vinyl chloride.
There are problems in that the foam collapses, spoiling the appearance, causing plasticizer to ooze out, and that the coating layer is more likely to peel off than the reinforcing core metal plate.

３，１４が形成されている。 The covering layer 3 is integrally molded by inserting the reinforcing core metal plate 2, and is a synthetic resin molded body having a specific gravity of 1.09 to 1.33. By this molding, the coating layer 3
The skin layer 1 is formed on the inner and outer layers of the skin layer 1 by promoting cooling through the reinforcing core metal plate 2 and the mold.

There is no risk of peeling.

観とを得ることができる。 In addition, in the copolymer of the coating layer 3, if polyethylene glycol diacrylate or polyethylene glycol dimethacrylate copolymerized with vinyl chloride exceeds 3.0% by weight, the heat resistance of vinyl chloride decreases, causing thermal deformation and causing roughness. If it is less than 0.1% by weight, its properties are similar to ordinary vinyl chloride homopolymers.
Although the hardness is high and the soft feel is poor, the surface becomes sticky and unevenness occurs, but if the above-mentioned substance that copolymerizes with vinyl chloride is within 3.0 to 0.1% by weight, a good tactile feel and elision effect can be obtained. Can be done. Further, if the degree of polymerization of the vinyl chloride copolymer is outside the range of 800 to 4000, the plasticizer will ooze out, resulting in the sticky phenomenon that is a drawback of vinyl chloride homopolymers, which is not preferable. Therefore, by setting the content of the substance copolymerized with vinyl chloride to 3.0 to 0.1% by weight and setting the degree of polymerization to 800 to 4000, a good feel and appearance can be obtained.

Kg／cm2以上とすることにより、強度的に問題がな
いとともに加工性もよくすることができる。 Further, in the alumina-silicate hollow body of the coating layer 3, if the specific gravity is less than 0.15, there is a problem in terms of strength, and if it exceeds 0.7, a large amount of addition is required to reduce the weight, which impedes workability. Also, the particle size is
If it is less than 5μ, the specific gravity will be high, requiring a large amount of addition, resulting in a decrease in strength, and if it exceeds 300μ,
It inhibits workability and becomes brittle in terms of strength. moreover,
If the compressive strength is less than 70Kg/ cm2 , it will be compressed during injection molding and it will be difficult to maintain the shape as a hollow body.
This is not preferable because it causes an increase in specific gravity. Also,
If the amount added is too large compared to the above copolymer, the properties of the vinyl chloride resin will deteriorate, and if it is too small, the weight of the synthetic resin will increase, which is inappropriate. Therefore, the alumina silicate hollow body has a specific gravity of 0.15 to 0.7, a particle size of 5 to 300μ, and a compressive strength of 70.
By setting it to Kg/cm 2 or more, there is no problem in terms of strength and workability can also be improved.
このようにして形成した被覆層３は比重が1.09

せることができる。 The coating layer 3 formed in this way has a specific gravity of 1.09.
~1.33, which can fully satisfy the performance of the armrest.

It was something to do. Note that the reason for the variation in specific gravity is that the density is different between the vicinity of the injection port and other locations.
