Abstract

The invention provides an internal combustion engine oil composite tackifier and a preparation method thereof. The preparation method comprises the following steps: firstly, selecting 50-60wt% of liquid glue 0010 and 40-55wt% of base oil, and selecting a clean special weighing and blending kettle; adding 50-60 wt% of liquid glue 0010 and 40-55 wt% of base oil into a special weighing reaction kettle, heating the special weighing reaction kettle, and performing circular stirring under a certain condition; carrying out two-whole cyclic mixing and carding on the raw materials in the special weighing reaction kettle by utilizing homogenizing equipment to obtain a composite tackifier; and sampling and inspecting: inspecting various indexes of the obtained composite tackifier. The composite tackifier is especially suitable for blending diesel engine oil with a long mileage of 100,000 km or above, is also especially suitable for product subdivision of gasoline and engine oil according to HTHSdata, has core data SSI of not more than 15, thickening efficiency of 0.8, high thickening efficiency and a small addition amount, reduces a cost, has excellent oxidation resistance, the oil film of an old vehicle can be improved, and the sealing performance of all components is enhanced.

Description

technical field [0001] The invention belongs to the technical field of a composite viscosifier for internal combustion engine oil, in particular to a composite viscosifier for internal combustion engine oil and a preparation method thereof. Background technique [0002] There are simple OCP type, PIB type, HSD type, and PMA type of existing blended internal combustion engine oil thickeners, but all kinds of thickeners have obvious shortcomings, such as poor low temperature performance, poor shear resistance, high price, Thickening efficiency is low. [0003] Therefore, a compound tackifier for internal combustion engine oil and a preparation method thereof are provided, which have excellent oxidation resistance, can improve the oil film of old vehicles, and enhance the sealing performance of various parts. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the present invention provides a composite tackifier for internal combustio...
