Description

Technical Field

[0001] The invention relates to a high-temperature chain oil composition for a rock wool machine and a preparation method thereof, belonging to the technical field of high-temperature chain oils. Background Art

[0002] Since the 19th century, high-temperature chains based on roller chains have been widely used in chain transmission and gear drive systems of drying rooms, ovens, hot furnaces, stretching tenters and other equipment in the textile, building materials, papermaking, plastic film and other industries. Since the chain drive itself is not only suitable for use under high torque and low speed, but also can show excellent performance in corrosive, humid environments and high-speed transmission, its application is becoming more and more popular;

[0003] Rock wool is a building insulation material with outstanding performance. It has the characteristics of thermal insulation, sound absorption, heat insulation, fire prevention, and breathability. It is the only external wall insulation material that can fully meet the A-level non-combustible insulation material in my country's current national and industry standards. The high-temperature chain transmission drive system based on roller chains has been widely used in the transmission and gear drive systems of rock wool production equipment.

[0004] Since rock wool production involves extremely high temperatures (reaching 300°C), traditional high-temperature chain oils (generally operating at around 250°C) will exhibit varying degrees of smoke, carbon deposits, oil dripping, agglomeration and other undesirable phenomena during use, leading to gas pollution in the rock wool processing workshop and shortening the refueling cycle, thus failing to meet the needs of normal equipment operation. Summary of the invention

[0005] The purpose of the present invention is to provide a high-temperature chain oil composition for a rock wool machine and a preparation method thereof. The high-temperature chain oil has excellent properties such as high oxidation resistance, low volatility loss, less carbon deposition, no coking, and extended refueling cycle. It can withstand the high temperature test of 280-300°C for a long time, can reduce gas pollution in the rock wool machine production workshop, reduce the number of equipment maintenance and maintenance costs, and is particularly suitable for chain lubrication of rock wool machine production equipment.

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0007] A high-temperature chain oil composition for a rock wool machine, comprising the following components: pentaerythritol ester, complex ester, type I antioxidant, type II antioxidant and anti-wear agent;

[0011] 1-4 parts of type I antioxidant;

[0012] 1-2 parts of type II antioxidant;

[0013] 1-2 parts of anti-wear agent.

[0014] Preferably, the pentaerythritol ester is a reaction product of a C9-C11 acid and pentaerythritol, wherein the viscosity at 40° C. is 120-140 mm 2 / s.

[0015] Preferably, the complex ester is a reaction product of pentaerythritol and dibasic acid, and has a viscosity of 460-540 mm2 / s at 40°C.

[0017] Preferably, the type II antioxidant is: polymer thioether phenol or a mixture of polymer thioether phenol and thiocarbamate, zinc thiocarbamate, and antimony thiocarbamate.

[0018] Preferably, the anti-wear agent is one or both of zinc thiocarbamate and antimony thiocarbamate.

[0019] The present invention also provides a method for preparing the above-mentioned rock wool machine high temperature chain oil composition, and the preparation method comprises the following steps:

[0020] S1: 20-40 parts of pentaerythritol ester and 60-80 parts of complex ester are mixed to prepare a base oil;

[0021] S2: prepare a mixture, add 1-4 parts of type I antioxidant and 1-2 parts of type II antioxidant into the base oil, and gradually and slowly raise the temperature to 90-100° C. while stirring, and keep the temperature for 30 minutes;
