Embodiment 1
[0022] Example 1 A preparation method of low-temperature transparent high-impact MBS resin
[0023] A preparation method of low-temperature transparent high-impact MBS resin, comprising the following preparation steps:
[0024] (1) Synthesis of rubber phase latex: Introduce nitrogen into the 10L reaction kettle, set the rotation speed of the reaction kettle to 100rpm, add the dispersion medium, remove the oxygen in the dispersion medium by vacuuming, and then pour the emulsifier into the reaction kettle , polymerization monomer, initiator, molecular weight regulator, adjust pH = 10 by pH regulator, control the solid content at 35%, raise the temperature to 7±1.5℃ under the protection of nitrogen, react at constant temperature for 20h, the conversion rate is ≥93% and the latex particles When diameter = 80-110nm, finish the reaction and get rubber phase latex;
[0025] (2) Resin phase graft polymerization: Introduce nitrogen into the 10L reactor, set the rotation speed of the r...
