preparation example Construction

[0031] A preparation method of a solid plasticizer based on fatty acid esters, comprising the following steps:

[0032] Step 1. Weigh fatty acid and polyol according to 30-90 parts by weight of fatty acid and 5-30 parts of polyol, and take sodium hydroxide as catalyst, and the weight of sodium hydroxide is 0.2%-0.4% of fatty acid, and then Pour the fatty acid, polyol and sodium hydroxide into the reaction kettle, heat it to 200 degrees Celsius, and keep it warm for 40 minutes to generate fatty acid ester;

[0033] Step 2. After reacting Step 1 to generate fatty acid ester, add a plasticizing release agent to the reactor for compounding. The mass part of the plasticizing release agent is 0.5-30 parts; wherein, the compounding temperature is at the above-mentioned plasticizing temperature. Above the melting point of the release agent, stir the reaction kettle for 30-40 minutes to fully mix the materials and set aside;

[0034] In step three, the material processed in step two i...

Embodiment 1

[0037] A solid plasticizer based on fatty acid ester comprises the following raw materials in parts by mass: 50 parts of fatty acid, 5-15 parts of polyol and 0.5-25 parts of plasticizing mold release agent. Wherein, the fatty acid is one or more of hydrogenated oil, stearic acid, lauric acid and oleic acid; the polyhydric alcohol is one or more of glycerin, sorbitol and pentaerythritol; The agent is one or more of oxidized wax, grafted wax and stearate.

[0038] The preparation method of the above-mentioned solid plasticizer based on fatty acid esters, in the raw materials, select stearic acid for use with fatty acid, polyhydric alcohol selects glycerin for use, and the oxidized wax of Honeywell is selected for use as plasticizing mold release agent; Including the following step:

[0039] Step 1. Weigh 1000 kg of stearic acid, 230 kg of glycerin (according to different formulas, glycerol can be between 100 and 300 kg), weigh 3 kg of sodium hydroxide, pour into the reaction ke...

Abstract

The invention discloses a solid plasticizer mainly based on fatty acid esters and a preparation method thereof. The raw material of the solid plasticizer comprises 30-90 parts of fatty acid, 5-30 parts of polyol and plastic 0.5-30 parts of mold release agent; the preparation method is that fatty acid and polyhydric alcohol generate fatty acid ester under the action of a catalyst, and the fatty acid ester is compounded with plasticizing mold release agent and then molded by a molding machine, that is, fatty acid ester-based solid plasticizer. During the use of the solid plasticizer obtained in the present invention, fillers are added according to process requirements, and the quality of the fillers is 10-60% of the total amount added, so as to meet the same proportion of replacement with liquid plasticizers. The present invention adopts a brand-new manufacturing process of solid plasticizer, and the obtained solid plasticizer is different from the traditional liquid plasticizer in form, making its operation easier and more convenient in the preparation of PVC auxiliary materials. The plasticizer replaces the liquid plasticizer, which can reduce the production cost and improve the production efficiency.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a solid plasticizer mainly based on fatty acid ester and a preparation method thereof. Background technique [0002] Plasticizers, also known as plasticizers, refer to substances that can increase the plasticity of polymer compounds or polymer materials. The existing plasticizers mainly refer to liquid plasticizers: dibutyl terephthalate, dioctyl phthalate, chlorinated paraffin, etc., which are widely used in the production of cable materials, floor materials, hoses, Artificial leather, pipe fittings, plates and other products, especially for polyvinyl chloride (PVC) processing. [0003] Polyvinyl chloride (PVC) is one of the five largest synthetic resins used in the world. It is a thermoplastic linear polymer produced by free radical polymerization of vinyl chloride monomer. PVC material has the advantages of high strength, low price, good chemical corrosion resistan...
