| Abstract: |
| By using three kinds of heat sensitive agents as experimental factors，a quadratic rotary combination design was adopted to establish the relationship between the properties of heat sensitive latex，specifically，the thermal stability and viscosity，and the addition level of the three kinds of heat sensitive agents，and the optimization formula of heat sensitive latex was achieved.The results showed that，when the addition levels of heat sensitive agent ammonium acetate， polyvinyl methyl ether and PEG600 were 0.5，0.9 and 0.75 phr，respectively，the thermal stability and viscosity of the heat sensitive latex after 16 h maturation were 52 s and 67.5 mPa·s，respectively，which met the molding technology requirement. |
