[0052] Prepare dioctyl phthalate-free rubber and plastic thermal insulation material according to the formula shown in Table 1, and the preparation process is as follows:
[0053] 1. Ingredients: Accurately weigh the required raw materials according to the formula requirements in Table 1.
[0054] 2. Internal mixing and open refining: the raw materials are separately internally mixed and opened, and rolled into raw material films for later use.
[0055] (1) Weigh 8 / 10 of the total amount of nitrile rubber, 4 / 5 of the chlorinated paraffin, all polyvinyl chloride, all vinyl chloride resin, all aluminum hydroxide, all calcium carbonate, all epoxy soybean oil, Four-fifths of paraffin-based rubber processing oil, all carbon black, all antimony trioxide, all dispersants, all paraffin, all stearic acid, all polyethylene glycol, all calcium stearate and all antioxidants are mixed, put After entering the internal mixing room of the internal mixer for internal mixing, the material is d...

The invention provides a rubber plastic thermal insulation material without dioctyl phthalate as well as a preparation method thereof. The rubber plastic thermal insulation material is prepared by taking nitrile rubber and polyvinyl chloride as main raw materials and adding chlorine vinegar resin, aluminum hydroxide, calcium carbonate, azodicarbonamide, chlorinated paraffin, epoxidized soybean oil, paraffin-based rubber processing oil, carbon black, antimony trioxide, a dispersing agent, paraffin, stearic acid, polyethylene glycol, calcium stearate, an anti-ageing agent, sulfur, zinc oxide andan accelerant. The rubber plastic thermal insulation material has high heat-insulating property and compression resilience property and does not contain dioctyl phthalate. Experiments prove that whenany one or more of components of the material are omitted or replaced, the heat-insulating property and the compression resilience property of the obtained rubber plastic thermal insulation materialare unsatisfactory.
Description
technical field [0001] The invention belongs to the technical field of rubber and plastic thermal insulation materials, and in particular relates to a dioctyl phthalate-free rubber and plastic thermal insulation material and a preparation method thereof. Background technique [0002] Rubber and plastic thermal insulation products are closed-cell elastic materials made of nitrile rubber and polyvinyl chloride as the main raw materials, together with various auxiliary materials, and foamed. However, the existing rubber and plastic products are usually filled with dioctyl ester, that is, dioctyl phthalate as a plasticizer, but this product will pollute the environment and stimulate human skin. Contents of the invention [0003] In view of this, the object of the present invention is to provide a dioctyl phthalate-free rubber and plastic thermal insulation material and a preparation method thereof. The rubber and plastic thermal insulation material provided by the present inve...
