に、引き離しが困難となり、作業性が悪くなる。Among these synthetic resin emulsions, it is better to have tackiness in consideration of actually adhering the ceramic member, and the thermoplastic resin emulsion and the synthetic rubber emulsion are preferable. The adhesive thin film obtained by kneading with the ceramic powder or the like preferably has a value of 1.5 to 3 kgf / cm 2 in terms of strength of adhesive force. The present inventors measured the adhesive force by 7 × 7 × 0.5.
cm asbestos slate board, the adhesive material from which the release sheet on one side is peeled off is attached with another epoxy resin adhesive,
On the other side of the adhesive material, peel off the release sheet, and attach a steel adhesive strength measurement attachment (having an adhesive area of 2.5 x 2.5 cm polished with No. 280 water resistant abrasive paper), After a pressure and a weight of 5 kg were left to stand for 15 minutes, the adhesive strength was measured using a tensile tester at a pulling speed of 2 mm / min. This adhesion is 1.5k
If it is smaller than gf / cm 2, when using an adhesive, one release sheet is peeled off and attached to the ceramic member to be joined, and when the other release sheet is peeled off, it floats on the adhesive thin film attached to the ceramic member. May occur. On the other hand, when the adhesive force is excessively higher than 3 kgf / cm 2 , it becomes difficult to separate the adhesive when it is once attached and it is desired to repair the adhesive, and the workability is deteriorated.
