preparation example Construction
[0040] The preparation method of above-mentioned formula sizing material, step is as follows:
[0041] In the open mill, the above-mentioned matrix rubber is firstly mixed evenly, and the color, active agent and vulcanization / accelerator are added in turn to knead evenly, and the above-mentioned protective wax test formula rubber is obtained.
[0042] The present invention also discloses a method for quickly evaluating the protective wax spit cream by using the above formula, which includes the following steps:
[0043] Step 1: Cut the protective wax test compound that needs to be tested for frosting into a sample of a specified size, stick cellophane on both sides and place it on a flat vulcanizing machine for vulcanization;
[0044] Step 2: Remove the cellophane from the vulcanized sample, and place it in an oven at 80°C for 3 minutes to 5 minutes to make the appearance color uniform;
[0045] Step 3: After taking dust-proof measures for the above-mentioned samples, place t...
Embodiment 2
[0067] In Example 2, each formula was only placed for 24 hours, and the obvious phenomenon of frosting can be observed, and the result of frosting rate is protective wax A > protective wax B > protective wax C, which is consistent with the theory;
[0068] To sum up: the combination of the test formula of the protective wax and the evaluation method of the present invention can quickly and accurately evaluate the frost of the raw material protective wax.
