Production formula and production method for high viscosity vaseline

Abstract

The invention relates to a production formula and a production method for a high viscosity vaseline. The method comprises treating an additive and blending raw materials, wherein the raw materials comprise a main raw material and an additive, the main raw material comprises the following components, by weight, 20-35% of a cerate, 30-55% of a base oil, and 18-40% of a wax oil, the additive is a butyl rubber, the butyl rubber is blended with the base oil to obtain an additive treatment material, a weight ratio of the butyl rubber to the base oil in the additive treatment material is 15-30%:70-85%, mixing stirring is performed for 12-16 hours at a temperature of 160 DEG C, and the additive treatment material is maintained at 135-145 DEG C for later use, the main raw material is subjected to a sulfuric acid treatment, and then is blended with the additive treatment material, the raw materials are completely stirred and constantly heated in a refinement kettle, the oil product is filtered to obtain the vaseline product. According to the method, results of a large number of experiments show that kinematic viscosity of the vaseline produced by the formula process can be increased to more than 25 mm<2> / s (100 DEG C) so as to enhance performance of the vaseline as a lubricant and increase an industrial application value.

Description

technical field [0001] The invention relates to the technical field of production of petrolatum products, in particular to a production formula and method of petrolatum capable of increasing the viscosity of petrolatum. Background technique [0002] Vaseline is the transliteration of vaseline. It is a kind of oily petroleum product. Its chemical composition is long-chain alkanes. , cosmetics, medicinal ointment, infiltration and perfusion capacitors, and can also be used in antirust and waterproofing agents. [0003] The conventional vaseline production process is to first blend the raw materials to make the physical properties of the blend meet the product requirements, and then refine the blend to remove non-ideal chemical components such as sulfur, nitrogen, oxygen and condensed ring aromatics contained in the raw materials. Traditional Vaseline blending components are vacuum distillate base oil and vacuum residue light dewaxing paste. [0004] Vaseline is a paste-like ...

Problems solved by technology

[0005] CN1156753A discloses a kind of vaseline formula, and this formula uses vacuum distillate oil dewaxed oil and vacuum distillate oil wax bottom oil as the blending component of petrolatum raw material, thereby reduces the vacuum distillate oil base oil and vacuum residue in the petrolatum raw material The content of oil light dewaxing paste expands the source of Vaseline raw materials, but does not solve the problem of increased viscosity of Vaseline

At present, the research related to the production technology of vaseline is mainly on its refining process, such as changing from the traditional acid-clay method and aluminum chloride method to the hydrogenation method (CN200810010254.6, CN201010141816.8), the main purpose of which is to reduce The three wastes pollution in the production process of vaseline, the increase of production yield, did not solve the problem of the increase of the viscosity of vaseline
