Embodiment 1
[0020] A kind of preparation method of the wallboard containing PVC modified material that the present invention proposes, comprises the following steps:
[0021] S1. Preparation of PVC modified components: In parts by weight, add 100 parts of purified water, 15 parts of emulsifier and 15 parts of ethanol into the reactor, stir evenly to form blend A;
[0022] S2. Add 4 parts of the polyvinyl chloride resin to the blend A, and stir evenly in a stirrer to form a nano-blend B;
[0023] S3. Add blend B to 15 parts of sponge cells, carry out grafting reaction in the reactor, then add 5 parts of maleic anhydride, stir evenly, and obtain polymer C after suction filtration;
[0024] S4. Polymer C was washed with 15 parts of ethanol for 10 minutes, and after drying for 10 minutes, polymer D was obtained;
[0025] S5. Preparation of PVC material template: mix polymer D and 20 parts of vinyl chloride polymer evenly, heat up to 50°C, suspend in water phase, chlorinate, increase the chlo...
