Widely used for furniture fashion, etc. but,
The surface pattern of the mold form is diverse and complex;
Generally, unevenness etc. are formed. For this reason, conventional worm clips cannot adequately cover the skin material.
Assembly is performed by applying adhesive to the surface of the mold form.

ンフォームの製造方法である。[Means for Solving the Problem] The present inventors conducted various studies on hot mold type polyurethane foam, and found that the skin is formed on polyurethane foam by stirring the foaming stock solution and injecting it into the mold once. During this process, chemical reaction conditions and external conditions (e.g. temperature) cause bubble generation and defoaming to occur at the contact area with the inner surface of the mold, resulting in a mixture of foam generation and defoaming at the contact area with the inner surface of the polyurethane foam (contact area).
It was determined that this is because the gas defoamed and formed a film. Therefore, the present inventors set the rise time (time from the start of foaming to the completion of foaming) of the foaming stock solution to within a certain period of time, and
By using a solvent type mold release agent, we attempted to make the hot mold type mold form skin-free. That is, the present invention produces polyurethane foam by injecting a foaming stock solution, which is a mixture and stirring of at least polyol, 6-isocyanate, amine catalyst tin catalyst, silicone oil, and water, into a lower mold, and rising it with the upper mold closed. This is a method for producing polyurethane foam, characterized in that the rise time is within 90 seconds and that a solvent-type mold release agent is used during foaming.
本発明において、溶剤タイプの離型剤としては、固形分

であるものが挙げられる。In the present invention, examples of the solvent-type mold release agent include those in which the solid content is mainly synthetic wax and the solvent is petroleum naphtha and a low boiling point solvent.
本発明において、ライズタイムを９０秒以＋Ｊｑとする

くするには、例えば錫触媒を少し多く添加すればよい。In the present invention, the reason why the rise time is set to 90 seconds or more +Jq is because if it exceeds 90 seconds, a skin will be formed on the surface of the mold form. In order to speed up the rise time in this way, for example, a little more tin catalyst may be added.

ムを得る事ができる。[Function] According to the present invention, by increasing the rise time to within 90 seconds and by applying a solvent-type mold release agent inside the mold during foaming, the foam is defoamed on the mold foam surface and a film is formed. It is possible to avoid this and achieve non-skinning. As a result, it is possible to easily coat the surface of the mold form with the coating phase, and to obtain a polyurethane foam that is excellent in physical properties and cost.

By spraying a solvent-type mold release agent onto the inner surface of the upper mold during foaming, the foam disappears on the surface of the mold form 11 and a film is formed, as shown in Figure 1. can be avoided and non-skinned. Therefore, since the surface of the mold form 11 is roughened, even if the skin material is coated on the mold form 11 with an adhesive, it can be prevented from peeling off. Also, since no skin is formed as in the conventional case, there is less abnormal noise.
更に、上記のように表皮材の被覆が可能となることから
