Example Embodiment
[0036] Example 1
[0037] The new process for preparing frosted PVC foamed wallpaper is realized in the following ways:
[0038] 1. Production process of coating section:
[0039] A. Preparation of paste: first put in plasticizer, epoxy soybean oil, potassium zinc stabilizer, one-half of the amount of viscosity reducer, put it in a mixer and stir at low speed for 5 minutes, and then continuously add AC foaming agent and PVC paste Resin, titanium dioxide, calcium carbonate. After the addition is complete, stir evenly, and finally add one-half of the viscosity reducer to adjust the viscosity to 3000 CPS, and filter.
[0040] The components of the paste are as follows, in parts by weight,
[0041] Plasticizer 60
[0042] Epoxidized soybean oil 12
[0043] AC blowing agent 5
[0044] Potassium zinc stabilizer 5
[0045] Viscosity Reducer 20
[0046] PVC paste resin 100
[0047] Titanium dioxide 15
[0048] Calcium carbonate 70.
[0049] The plasticizer is DOP (dioctyl phthalate); the AC foaming a...
Example Embodiment
[0066] Example 2
[0067] The new process for preparing the imitation frosted PVC foamed wallpaper, the paste ratio in the coating section is as follows, and the others are the same as in Example 1.
[0068] The components of the paste are as follows, in parts by weight,
[0069] Plasticizer 65
[0070] Epoxidized soybean oil 11
[0071] AC blowing agent 5.5
[0072] Potassium zinc stabilizer 5
[0073] Viscosity Reducer 15
[0074] PVC paste resin 120
[0075] Titanium Dioxide 10
[0076] Calcium carbonate 80.
[0077] The plasticizer is DOP (dioctyl phthalate); the AC foaming agent is azodicarbonamide; and the viscosity reducing agent is a low-sulfur and low-aromatic hydrocarbon solvent.
