[0057] A kind of preparation method of the composite material of low styrene volatilization unsaturated polyester resin, the steps are as follows:
[0058] 1. Take 5-90% styrene and 10-95% unsaturated polyester by weight, add them to the reaction vessel, and mix and stir for 1-5 hours;
[0059] 2. According to the total weight of styrene and unsaturated polyester, add 1-25% of inorganic layered material and 0.1-10% of accelerator, mix and stir for 1-5 hours to obtain pre-intercalation;
[0060] 3. According to the total weight of styrene and unsaturated polyester, add 0.1-10% curing agent, and perform post-curing treatment for 6-12 hours.
[0061] The curing treatment is: put the material in a constant temperature drying oven at a temperature of 40°C, heat and cure for 3-6 hours, and then take it out; then put the material in a drying room at a temperature of 80°C, and cure for 3-6 hours to eliminate The internal residual stress of the material is taken out to obtain the prod...

[0072] Step 1. Take 600kg of styrene and 400kg of unsaturated polyester by weight, add them to the reaction vessel, and mix and stir for 1-5 hours;
[0073] Step 2. According to the total weight of styrene and unsaturated polyester, add 100 kg of inorganic layered material and 10 kg of accelerator into the reaction vessel, mix and stir for 1-5 hours, and obtain a pre-intercalated product;
[0074] Step 3: According to the total weight of styrene and unsaturated polyester, add 10 kg of curing agent into the reaction vessel, stir for 2-40 minutes, and release the material;
[0075] Step 4. Send the material into a constant temperature drying oven at a temperature of 40°C, heat and cure for 3-6 hours, and then take it out;
[0076] Step 5: put the material into the drying room again, at a temperature of 80°C, cure for 3-6 hours, eliminate the internal residual stress of the material, take it out, and obtain the product.
[0077] In this process, the volatilization of styrene bef...
