[0002] At present, it is recognized that the coolant is composed of a large amount of water. Heavy-duty vehicles such as tanks have higher cooling requirements for their engines than ordinary vehicles. The common The coolant cannot meet the requirements of this type of heavy-duty and heavy-duty vehicles, and it will also cause damage to the engine cooling system

Embodiment Construction

[0010] Such as figure 1 The coolant oil used in a heavy-duty car is mixed and stirred with 1000g of ethylene glycol, 300-500g of deionized water, and 5-15g of triethanolamine, and heated to 90°-100° during the stirring process to obtain a mixed solution 1 , add 0.5-10g of anti-foaming agent to mixed solution 1, copper corrosion agent: 2-4g of benzotriazole, organic acid: 5-10g of phosphoric acid, fatty acid: 0.2-5g of polyacrylic acid, anti-cavitation: 0.2-5g of borax Afterwards, carry out sufficient stirring to obtain the mixed solution 2, add alkali agent: NaOH3-5g in the mixed solution 2, adjust the pH value of the solution to 7 to obtain the mixed solution 3, filter the mixed solution 3 until it is transparent, and wait for the solution to be cooled and then canned to obtain finished product.

Abstract

The invention discloses coolant oil for heavy-load type vehicles. A preparation method of the coolant oil is characterized by comprising the following steps of: mixing and stirring 1000g of ethylene glycol, 300-500g of deionized water and 5-15g of triethanolamine, and heating to 90-100 DEG C in a stirring process to obtain a mixed solution I; adding 0.5-10g of anti-foaming agent, 2-4g of copper corrosive, namely benzotriazole, 5-10g of organic acid, namely phosphoric acid, 0.2-5g of fatty acid, namely polyacrylic acid, and 0.2-0.5g of sodium borate for resisting cavitation to the mixed solution I, and then fully stirring to obtain a mixed solution II; and adding 3-5g of alkaline agent, namely NAOH to the mixed solution II, adjusting the pH value of the solution to 7 so as to obtain a mixed solution III, filtering the mixed solution III till being transparent, cooling the solution and then canning to obtain the finished product. The Coolant oil is environmentalLY-friendly and healthy.

Description

technical field [0001] The invention relates to a cooling oil with high boiling point, low freezing point, strong heat dissipation and environmental protection used in heavy-duty vehicles. Background technique [0002] At present, it is recognized that the coolant is composed of a large amount of water. Heavy-duty vehicles such as tanks have higher cooling requirements for their engines than ordinary vehicles. Common coolants in the world cannot meet the requirements of such heavy-duty and heavy-duty vehicles. requirements, and can also cause damage to its engine cooling system. However, the product greatly reduces the water content without affecting the ability of the base fluid to mix various additives; obtains higher boiling point, low specific heat, low freezing point and low temperature viscosity characteristics. It can help the engine warm up quickly when it is at low temperature and cold start. [0003] When the water content is low enough to meet the boiling point ...
