The Sponge sand paper that in patent application document prepared by embodiment 1 is labeled as application examples 9, and substrate is polyurethane sponge, glue in application examples 9
Knot material is epoxy modified resin, and abrasive material is high-temperature calcination Brown Alundum.
According to the stripping of GB/T7122-1996 " the measurement floating roller method of high-strength adhesive peel strength " detection application examples 1-9
From intensity, the Sponge sand paper of application examples 1-9 is placed at 50 DEG C, 75 DEG C, 105 DEG C and 130 DEG C and places 3min, is subsequently cooled to room
Temperature, then its peel strength is measured, it will test result and be reported in Table 5 below.
The heat resistance of 5 Sponge sand paper binder of table detects
It can be seen from data in table 5 according to the binder of embodiment 1-5 preparation after Sponge sand paper is made with sponge, sand paper,
Peel strength at different temperatures is different, and as the temperature rises, peel strength Strength Changes are little, when temperature is increased to
At 130 DEG C, peel strength decline, but fall is small, peel strength still in 6.04kN/m or more, illustrates the embodiment of the present invention
The binder of 1-5 preparation is heat-resist in Sponge sand paper use process is made, will not be old because of the heat in friction process
Change, viscosity reduces.
Application examples 6 is made of binder prepared by comparative example 1, comparative example 1 because being not added with heat-barrier material in heat-resisting stabilizing agent,
It can be seen from data in table 5 as the temperature rises, the peel strength of Sponge sand paper is gradually reduced, at 130 DEG C, removing
Intensity is only 4.67kN/m, illustrates that the heat resistance of binder can be significantly improved by adding heat-barrier material.
Application examples 7 is made of binder prepared by comparative example 2, and comparative example 2 is glued because being not added with modified water glass in binder
Tie agent as the temperature rises, peel strength constantly reduces, and illustrates that the heat-proof aging of binder can be improved by adding modified water glass
Performance improves the cohesive force of binder at high temperature.
Application examples 8 is made of binder prepared by comparative example 1, comparative example 3 because being not added with elasticity modulus filler in binder,
The peel strength of binder prepared by comparative example 3 as the temperature rises, constantly reduces, and at 130 DEG C, peel strength is only
4.61kN/m illustrates to add elasticity modulus filler, can improve the heat resistance of binder.
Application examples 9 is the Sponge sand paper of prior art preparation, and cementitious matter is epoxy modified resin, can by data in table 5
To find out, as the temperature rises, peel strength is gradually decreased, and the heat resistance of cementing material is poor.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
Member can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but as long as at this
All by the protection of Patent Law in the scope of the claims of invention.
