Development and evaluation of a high-strength and anti-high temperature pre-crosslinking gel

There are many kinds of pre-crosslinking gel being used at present, but their high temperature resisting performance are poor. The general temperature resisting capacity is only about 120 degrees C. Aiming at the poor resistance to high temperature of current pre-crosslinking gel, an anti-high temperature pre-crosslinking polymer gel is developed in this paper. Experimental results show that this product has appropriate swelling ability, better anti-extruding strength, better deformability and elasticity. The temperature resisting capacity in freshwater can reach as high as 150 degrees C,and it still has comparatively higher strength after high temperature treatment.
