Embodiment 1

[0027] The first step, primary esterification reaction: in parts by weight, 540-550 parts of stearic acid, 135-150 parts of pentaerythritol, 0.2-1.0% of catalyst, under vacuum conditions or under the protection of inert gas, heat up to 160- 250°C, react for 2 to 6 hours until anhydrous comes out, finish the first step reaction and cool down to normal temperature to obtain the first-time esterified ester product A.

[0028] The second step, secondary esterification reaction: in parts by weight, C 16-18 Add 520-550 parts of higher aliphatic alcohol, add 160-170 parts of phthalic acid, 0.2-1.0% of catalyst, raise the temperature to 160-250°C under vacuum conditions or under the protection of inert gas, and react to nothing after 2-6 hours. After the water comes out, the first step reaction is completed and the temperature is lowered to normal temperature to obtain the secondary esterified ester product B.

[0029] The third step, compounding: take 25-30 parts of A ester product ...

Embodiment 2

[0031] The first step, primary esterification reaction: in parts by weight, 270-330 parts of oleic acid, 90-100 parts of glycerol, 0.2-1.0% of catalyst, under vacuum conditions or under the protection of inert gas, the temperature is raised to 160 ~250°C, react for 2~6 hours until anhydrous comes out, finish the first step reaction and cool down to normal temperature to obtain the first-time esterified ester product C.

[0032] The second step, the secondary esterification reaction: in parts by weight, 380-420 parts of lauryl alcohol, 160-170 parts of terephthalic acid, 0.2-1.0% of catalyst, under vacuum conditions or under the protection of inert gas, Raise the temperature to 160-250°C, react for 2-6 hours until no water comes out, finish the first step reaction and cool down to normal temperature to obtain the secondary esterified ester product D.

[0033] The third step, compounding: take 25-30 parts of C ester products of primary esterification, take 50-60 parts of D ester...

Embodiment 3

[0035] The first step, one-time esterification reaction: in parts by weight, 380-450 parts of lauric acid, 130-150 parts of pentaerythritol, 0.1-1.0% of catalyst, under vacuum conditions or under the protection of inert gas, the temperature is raised to 160-250 ℃, react for 2 to 6 hours until anhydrous comes out, finish the reaction and cool down to normal temperature to obtain the esterified ester product E once;

[0036] The second step, secondary esterification reaction: in parts by weight, 190~210 parts of lauryl alcohol, stearin (C 16～18 ) 260-275 parts of alcohol, add 80-90 parts of phthalic acid, add 70-80 parts of adipic acid, 0.1-1.0% of catalyst, heat up to 160-250°C under vacuum or under the protection of inert gas, After 4 to 10 hours of reaction until no water comes out, the first step of reaction is completed and the temperature is lowered to normal temperature to obtain the secondary esterified ester product F;

[0037] The third step, compounding: take 30-40 p...

Abstract

The invention relates to a method for manufacturing lubricant, in particular to a manufacturing method of polyvinyl chloride ester inner / outer lubricant, which is applicable for the production of the polyvinyl chloride plastic processing industry. The method comprises the steps as follows: esterification reaction with polylol and fatty acid is conducted under the effect of catalyst in order to produce a primary ester product; esterification reaction with binary acid and fatty acid is carried out under the effect of catalyst to produce a secondary ester product; the ester products are remixed in the reactions twice with wax or fatty acid metal salt or the mixture of wax and fatty acid metal salt to produce the final product. The invention has the advantages of reasonable technique design, excellent lubricating performance, good stability, cooperative effect, etc.

Description

technical field [0001] The invention relates to a method for manufacturing a lubricant, in particular to a method for manufacturing a polyvinyl chloride ester internal and external lubricant, which is suitable for production in the polyvinyl chloride plastic processing industry. Background technique [0002] Lubricants are an important class of additives in plastic processing. It can be called a "catalyst" for plastic processing. At present, there are few varieties of ester lubricant products in PVC plastic processing, there is not much room for selection, the technical content of product performance is not high, and the lubricating performance of lubricants is not ideal. At present, there is no or very few ester lubricants with both internal and external lubricity, stability and synergy in this field. PVC plastic processing enterprises urgently need high-quality lubricant products to meet the market demand for high-grade plastic products. Contents of the invention [0...
