Problems solved by technology

However, most of the existing plastic additives have a single function, resulting in the need to add a variety of additives during the plastic molding process. For example, when preparing plastic casings for home appliances, lubricants, stabilizers, mold release agents, antistatic agents and Wear-resistant agent, etc., such complicated addition in the preparation process will not only complicate the production process, but also the quality of the produced products will be unstable

Embodiment 1

[0023] The preparation of octadecyl oleic acid amide comprises the steps of: taking oleic acid and octadecylamine as raw materials, taking oleic acid and octadecylamine in a molar ratio of 1.005:1, adding a catalyst of 0.45% of the total weight of raw materials , at a temperature of 185° C. and a pressure of 0.5 MPa, react for 6 hours to obtain octadecyl oleic acid amide; wherein, the composition of the catalyst includes: 85% SiO 2 , 14.5% TiO 2 and 0.5% La2 o 3 .

[0024] In this example, the synthetic conversion rate (calculated as C18) of octadecyl oleic acid amide is >98.5%, the purity (total amide content) is >=98.5%, and the product yield is >=95.5%.

Embodiment 2

[0026] Application of octadecyl oleic acid amide to prepare PP film: add octadecyl oleic acid amide to the screw extruder together with PP resin, maleic anhydride grafted PP, sodium stearate and antioxidant 168 in an amount of 5‰ Melt and mix in the machine, and prepare PP film-1 through extrusion and biaxial stretching process.

[0027] In addition, without adding stearyl oleic acid amide, directly add PP resin, maleic anhydride grafted PP, sodium stearate and antioxidant 168 into the screw extruder to melt and mix, and prepare by extrusion and biaxial stretching process into PP film-2.

[0028] According to GB / T 12802.2-2004 standard, the antistatic performance of PP film was tested. After testing, the surface resistivity of PP film-1 was 10 10 Ω, the surface resistivity of PP film-2 is 10 12 Ω.

[0029] Example 2

[0030] Preparation of PP scratch-resistant masterbatch: In terms of mass percentage, take 70% epoxy resin, 15% octadecyl oleic acid amide, 1% maleic anhydrid...

Embodiment 3

[0033] Preparation of anti-scratch and antistatic masterbatch: 75% PE, 10% stearyl oleic acid amide, 5% stearylamine polyoxyethylene ether, 5% monoglyceride and 5% hydroxyethyl Ethylene bis stearamide is mixed, melted and granulated to obtain scratch-resistant and anti-static masterbatch.

[0034] After testing, the PP film made of the above-mentioned scratch-resistant and anti-static masterbatch was measured to have a surface resistivity of 10 10 Ω, and its color difference value is 0.42, indicating that the prepared PP film has good scratch resistance and antistatic properties.

Description

technical field [0001] The invention belongs to the technical field of polymer compounds, and in particular relates to stearyl oleic acid amide, its preparation method and application. Background technique [0002] Plastic is a material with synthetic or natural polymer compounds as the main component, which can be plasticized and formed under certain conditions, and the final product can keep its shape. The main component of plastic is resin, and its basic performance depends on the nature of resin. Resin accounts for 40-100% of the total weight of plastic. In the plastic molding process, in order to improve the processing performance of the resin or to improve the performance of the resin itself, it is often necessary to add plastic additives. [0003] With the development of the plastic synthetic resin industry, the application field of the plastic additive industry has been continuously expanded, and the product variety has increased significantly. The plastic additive ...
