Master batch containing heat radiation shielding component, and heat radiation shielding transparent resin form and heat radiation shielding transparent laminate for which the master batch has been used

Abstract

In a master batch containing a heat radiation shielding component, which is used to produce heat radiation shielding transparent resin forms, the master batch has as chief components a thermoplastic resin and a hexaboride represented by XB 6 , wherein X is at least one selected from La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Y, Sm, Eu, Er, Tm, Yb, Lu, Sr and Ca. The hexaboride, which is a heat radiation shielding component, is contained in an amount of from 0.01 part by weight or more to less than 20 parts by weight based on 100 parts by weight of said thermoplastic resin. The use of this master batch enables simple production of heat radiation shielding transparent resin forms having a high visible-light transmission power and a high heat radiation shielding performance, without relying on any high-cost physical film formation methods.

What is claimed is:  
     
         1 . A master batch containing a heat radiation shielding component, which is used to produce heat radiation shielding transparent resin forms; the master batch comprising: 
 as chief components a thermoplastic resin and a hexaboride represented by XB 6 , wherein X is at least one selected from La, Ce, Pr, Nd, Gd, Tb, Dy, Ho, Y, Sm, Eu, Er, Tm, Yb, Lu, Sr and Ca;    said hexaboride, which is a heat radiation shielding component, being contained in an amount of from 0.01 part by weight or more to less than 20 parts by weight based on 100 parts by weight of said thermoplastic resin.    
     
     
         2 . The master batch according to  claim 1 , wherein said thermoplastic resin is at least one selected from an acrylic resin, a polycarbonate resin, a polyether-imide resin, a polystyrene resin, a polyether-sulfone resin, a fluorine resin, a polyolefin resin and a polyester resin.  
     
     
         3 . The master batch according to  claim 1  or  2 , wherein said hexaboride comprises fine particles having an average particle diameter of 1,000 nm or less.  
     
     
         4 . The master batch according to  claim 1  or  2 , wherein said hexaboride have been surface-treated with at least one selected from a silane compound, a titanium compound and a zirconia compound.  
     
     
         5 . A heat radiation shielding transparent resin form characterized by being obtained by diluting and mixing the master batch according to  claim 1  with a thermoplastic-resin form material of the same type as the thermoplastic resin of the master batch or a different type of thermoplastic-resin form material having a compatibility with the master batch, and forming the resulting mixture in a stated shape.  
     
     
         6 . A heat radiation shielding transparent laminate characterized by being obtained by laminating the heat radiation shielding transparent resin form according to  claim 5  to other transparent form.
