Modified ADC (azodicarbonamide) foaming agent with heat conduction and preparation method of modified ADC foaming agent

Abstract

The invention discloses an ADC (azodicarbonamide) foaming agent with heat conduction and a preparation method of the ADC foaming agent. The ADC foaming agent comprises the ADC foaming agent and a ZnO / MgO composite material, wherein the using amount of the ZnO / MgO composite material is 5%-40% of the mass of the ADC foaming agent, and the mass content of ZnO in the ZnO / MgO composite material is 1-50%. The method comprises the following steps: uniformly mixing the ADC foaming agent and the ZnO / MgO composite material in a mixing machine for 10-30min at normal temperature, wherein the using amount of the ZnO / MgO composite material is 5%-40% of the mass of the ADC foaming agent, and the mass content of ZnO in the ZnO / MgO composite material is 1-50%. The ADC foaming agent disclosed by the invention has the beneficial effects that the modified ADC foaming agent provided by the invention has good heat conduction performance in the foaming process, so that the foaming time is shortened, on the one hand, the energy consumption of a manufacturer is reduced, and the on the other hand, the utilization rate of equipment is improved.

Description

technical field [0001] The invention relates to the field of ADC foaming agents, in particular to a modified ADC foaming agent with thermal conductivity and a preparation method thereof. Background technique [0002] As we all know, ZnO is an excellent ADC foaming agent additive, which can significantly reduce the decomposition temperature of pure ADC foaming agent, so that the decomposition temperature of the foaming agent is consistent with the processing temperature of rubber and plastic materials, so that qualified foam can be prepared. Soaked products. [0003] Due to the good activation performance of ZnO on ADC foaming agent, it is widely used in the modification research and application of ADC foaming agent. The research found that the activation performance of nano-ZnO is better than that of conventional ZnO. However, the particle size of nano-ZnO is small, the surface energy is high, the particles are in an unstable state, and they are prone to agglomeration, whic...

[0005] However, since SiO 2 It has a certain thermal resistance. During the foaming process of the compound foaming agent, it is not conducive to the conduction of heat inside the foaming substrate, thus requiring a longer foaming time. On the one hand, it increases the energy consumption of the manufacturer, and on the other hand On the one hand, it reduces the utilization rate of equipment
