Definitions
- the present invention relates to a method for manufacturing a heat insulating plate composed of a face material and a hard foam synthetic resin core material.
- foamed synthetic resin to be obtained examples include polyurethane foam, urethane-modified polyisocyanurate foam, and polyurethane foam.
- foaming agents for producing the above foamed synthetic resin.
- the main use of trichlorofluorometer (CFC-11) has been used.
- water was usually used together with CFC-11.
- dichlorodifluoromethane (CFC-12) which has a low boiling point (gas at normal temperature and normal pressure), is also used together.
- Fluorocarbons which are extremely stable in the atmosphere, such as CFC-l1 and CFC-12, which have been widely used in the past, reach the ozone layer above the atmospheric layer without being decomposed, It decomposed by the action, and it became possible that the decomposed product would destroy the ozone layer.
- hydrofluorocarbon As a compound that has a boiling point that can function as a foaming agent and does not have the risk of depleting the ozone layer, instead of hydrofluorocarbon, it is possible to use hydrofluorocarbon, pentane, hexane, heptane, or ozone. There are hydrocarbons such as butane and isomers of these compounds.
- water that generates carbon dioxide gas by the reaction with polyisocyanate is also used in combination with the above foaming agent or water alone because the generated carbon dioxide gas has no risk of destruction of the ozone layer. It has been used as an agent.
- foamed synthetic resin obtained by using them as a foaming agent has physical properties in comparison with the conventional foamed synthetic resin using CFC-11. Is seen to decrease. In particular, dimensional stability is significantly degraded due to form shrinkage. By increasing the density, it is possible to maintain the performance of the foamed synthetic resin, but in that case, cost is inevitable.
- a rigid foam synthetic resin material is sprayed or injected between two opposing face materials and foam-hardened to produce a heat-insulating plate composed of the face material and the hard foam synthetic resin core material.
- Insulating plates obtained by this method are broadly classified into boards and siding materials.
- the board uses craft paper or plywood as a surface material, and is used as a heat insulating material for the insulation wall of a freezer.
- the siding material uses a metal plate or the like as the face material, and is used as it is as the outer wall of the house.
- the small face of the board or siding is made of foam composite Since the resin is bare and exposed, even if the synthetic foam resin exposed on this small surface shrinks even a little, it becomes very noticeable and easily becomes a problem. Furthermore, the field of rigid foam synthetic resin boards competes with polystyrene-based boards, etc., and the field of rigid foam synthetic resin siding materials competes with ceramic siding materials, etc. Demands for low density and low cost are also very high. Furthermore, in recent years, the use of rigid foamed synthetic resins for high airtightness and high heat insulation in the housing field has been increasing.
- a hard polyurethane modified poly-sodium foam with higher flame retardancy than that of the hard polyester foam may be considered.
- the raw material of rigid urethane-modified polyisocyanate foam especially the raw material of rigid urethane-modified polyisocyanurate foam, use aromatic polyester diol from the viewpoint of physical properties such as flame retardancy.
- the crosslink density decreases, and form shrinkage tends to occur more easily than in rigid polyurethane foam.
- a polymer-dispersed polyol is a composition in which polymer fine particles obtained by polymerizing a monomer having a polymerizable unsaturated group in a polyol such as a polyether polyol or a polyester polyol are dispersed. Used as a raw material for soft or semi-rigid polyurethane foam, it has been used to improve the physical properties of these polyurethanes. In the above-mentioned technology for producing a hard polyurethane foam having good dimensional stability by adding a polymer-dispersed polyol to a polyol having a high hydroxyl value, it is considered that the polymer fine particles exert some effect.
- the process for producing the polymer monodispersed polyol is carried out in a saturated polyol having no polymerizable unsaturated group, and in some cases, an unsaturated polymer having a polymerizable unsaturated group. It is known that polymerization of a monomer having a polymerizable unsaturated group is carried out under conditions in which all is present, followed by removal of unreacted components. Various polyols and polyester polyols are known as polyols.
- the above-mentioned conventional polymer monodispersed polyol is a polymer dispersed polyol having a low hydroxyl value (50 mg K0HZg or less) used as a raw material of a soft or semi-rigid polyethylene foam. . Therefore, conventional low-hydroxyl value polymer monodisperse polyols have poor compatibility with high hydroxyl value polyols for rigid polyurethane foams, and when used in combination, low-hydroxyl value polyols and polymer fine particles are separated. However, since the viscosity of the polyol mixture is increased, it has been difficult to use a conventional polymer dispersion polyol having a low hydroxyl value as a raw material for a hard polyurethane foam.
- Japanese Patent Publication No. Hei 7 — 89886 has a description about polymer-dispersed polyol with high hydroxyl value
