Problems solved by technology

[0005] The release oil can meet the requirements in practical application, especially in summer or when the temperature of the production workshop is high, but in winter, there will be problems, such as: due to the high kinematic viscosity of the product, it is not easy to fill, and the entire capillary is covered The time is too long; also because of the unique physical and chemical indicators of the product, it is difficult to dilute it with other materials with similar properties

Embodiment 1

[0032] Step 1, add 116.07kg (1000mol) of fumaric acid and 354.12kg (1900mol) of lauryl alcohol in the polymerization kettle, add 28kg of dilute sulfuric acid (5%), charge into nitrogen to convert the air in the polymerization kettle to react, after the reaction Decompress and discharge water, which is lauryl fumarate.

[0033] Step 2: Add 1.16kg of dibenzoyl peroxide initiator into the polymerization kettle and stir, keep the reaction temperature at 160°C, after 8 hours of polymerization reaction, discharge the polymer in the polymerization kettle, filter and remove it at a temperature above 100°C, etc. Impurities, that is, fumaric acid laurel resin.

[0034] Stir 75kg of the above lauryl resin fumarate and 25kg of trimethylolpropane trioleate at a temperature of about 100°C for 20 minutes to obtain a release oil for aluminum casting crystallizers, which is naturally cooled and packaged.

Embodiment 2

[0036] Step 1, the maleic acid of 116.07kg (1000mol) and the arachidyl alcohol of 597.1kg (2000mol) are added in the polymerizer, add 71.32kg dilute sulfuric acid (5%), fill into nitrogen and change the air in the polymerizer to react, react After decompression to discharge water, it is peanut ester maleate.

[0037] Step 2: Add 0.58kg of lauroyl peroxide initiator to the polymerization kettle and stir, keep the reaction temperature at 180°C, after 4 hours of polymerization, discharge the polymer in the polymerization kettle, filter and remove other impurities at a temperature above 100°C, It is maleic acid peanut resin.

[0038] Stir 25kg of the above-mentioned peanut ester maleate, 70kg of pentaerythritol tetraoleate, and 5kg of tributyl phosphate at a temperature of about 100°C for 20 minutes to obtain a release oil for aluminum casting crystallizers, which is naturally cooled and packaged.

Embodiment 3

[0040] Step 1, the maleic anhydride of 98.02kg (1000mol) and the stearyl alcohol of 527.59kg (1950mol) are added in the polymerizer, add 12.51kg cation exchange resin, charge into nitrogen and change the air in the polymerizer to react, reduce after the reaction Press out the water, which is stearyl maleate.

[0041] Step 2: Add 0.87kg of tert-butyl hydroperoxide to the polymerization kettle and stir, keep the reaction temperature at 170°C, after the polymerization reaction for 6 hours, discharge the polymer in the polymerization kettle, filter and remove impurities such as at a temperature above 100°C, It is stearyl alcohol maleate resin.

[0042] Stir 50kg of stearyl alcohol maleate resin, 46kg of dipentaerythritol oleate, and 4kg of triisooctanyl phosphate at a temperature of about 100°C for 20 minutes to form a mold release oil for aluminum casting crystallizers. Cool naturally Package.

Abstract

The invention provides butenedioic acid resin, a preparation method thereof, and preparation of a degradable micro-scale lubricant therewith. The butenedioic acid resin is characterized by being prepared from following raw materials: butenedioic acid or butenedioic acid anhydride and fatty alcohol, wherein the molar ratio of the butenedioic acid or the butenedioic acid anhydride to the fatty alcohol is 1:1.9-2. Raw materials for preparing aluminum-casted crystallizer demoulding oil include the butenedioic acid resin. The aluminum-casted crystallizer demoulding oil is stable, is uniform in dispersion and is low in kinematic viscosity.

Description

technical field [0001] The invention belongs to the technical field of demoulding, and relates to a butenedioic acid resin, a preparation method thereof and the use of the resin to prepare demoulding oil for aluminum casting crystallizers. Background technique [0002] Aluminum alloy processing and casting demolding Traditionally, a layer of graphite grease is applied to the surface of the mold. The disadvantages of this processing technology are high labor costs, uneven manual application, serious smoke during high temperature casting, severe damage to the mold, and smooth surface of the finished product. Poor degree etc. [0003] Due to the above shortcomings, the new casting and demoulding process uses capillaries densely covered on the surface of the crystallizer, and the capillaries are filled with vegetable oil such as soybean oil or some lubricating oil with better high temperature performance for lubrication and demoulding, which overcomes the above shortcomings. Hi...
