Abstract: PURPOSE:To remove dust and dirt easily by a method wherein a silicon reactive resin in which silicon and a synthetic resin are reacted is used as an additive, and interior accessaries of a refrigerator are molded of a resin whose material is the same as the synthetic resin and provided inside the refrigerator. CONSTITUTION:Resin is first graft polymerized with silicon whose main component is dimetyle polysiloxane to obtain silicon reactive resin 3. Then, by using the silicon reactive resin 3 as an additive, the same resin is injection molded to obtain a food container for vegetable. Thus, as the silicon reactive resin 3 obtained by the graft polymerization of silicon and a synthetic resin is added to the resin whose material is the same as the synthetic resin, it is difficult for silicon to flow out of the silicon reactive resin 3. Further, by the water repulsiveness of the silicon which is added into the resin, the surface of the food container 2 is protected. By this, only by wiping the food container 2 with dish cloth or the like, dust can be easily removed. That is, the food container 2 can be easily and effectively cleaned.

Abstract: PURPOSE:To provide an adiabatic door for a refrigerator, etc., strong in the adhesivity of a cap door to an urethane resin adiabatic material used HCFC 123 as a foaming agent and not causing cracking and discoloration of the cap door by employing the resin cap door comprising a specific material. CONSTITUTION:The objective product is produced by integrally foaming an urethane adiabatic material in a adiabatic space formed from a resin cap door and a metal door surface plate. The adiabatic material is produced from an organic polyisocyanate containing 40-90wt.% of polymeric MDI, etc., as a NCO component, while HCFC 123, HCFC 141b or their mixture is used as the foaming agent. The resin cap door comprises a composition containing a graft copolymer produced by copolymerizing 30-50wt.% of (i) a vinyl cyanide compound with (ii) 50-70wt.% of an aromatic vinyl compound in the presence of a conjugated dienic rubber, a copolymer comprising 30-50wt.% of the component i and 50-70wt.% of the component ii, and n-butyl acrylate/n-propyl acrylate copolymer coated with the copolymer comprising 30-50wt.% of the component i and 50-70wt.% of the component ii.
