Abstract
The invention discloses a dry release agent for the injection molding industry. In percentage by weight, the dry release agent consists of 3-15% of soybean emulsified honey, 0.3-1.0% of polydimethylsiloxane, 0.3-1.0% of 107 silicon rubber and the balance being petroleum ether (60-90). The invention also provides a preparation method of the release agent. The method comprises the following steps: adding the soybean emulsified honey to the petroleum ether and rapidly stirring until the soybean emulsified honey is completely dissolved; and then adding 201-500cs of silicon oil and 107 silicon rubber and stirring until the complete dissolving forms so as to obtain a finished product. The release agent disclosed by the invention is good in release effect, a released molded part is smooth in surface and free from oil stain, the subsequent processing of the plastic surface is not affected and the cost is low, and moreover, a problem on a use method of the soybean emulsified honey is solved, so that the green production is really achieved.
Description
Technical field
The invention belongs to chemical field, particularly relate to a kind of releasing agent, specifically a kind of dryness releasing agent and preparation method thereof of injection industry.
Background technology
The dryness releasing agent used in the market has following several:
1. use soybean lecithin as main release materials, be applicable to need secondary operations and the exigent plastic products of effects on surface oil stain;
2. silicone release, common are with high viscosity 201 silicon rubber.
3. polyvinyl alcohol releasing agent, polyvinyl alcohol with low degree of polymerization water-soluble or water, alcohol mixeding liquid, add a small amount of glycerine simultaneously.
4. fluoroplastics releasing agent, the features such as it is low that it has surface energy, and heat endurance is high, release property is good.
Above four class dryness releasing agents can be used for the demoulding of different materials or different technologies requirement, but have a common shortcoming, and cost is higher, competitive poor.
Summary of the invention:
For above-mentioned technical problem of the prior art, dryness releasing agent that the invention provides a kind of injection industry and preparation method thereof, dryness releasing agent of described this injection industry and preparation method thereof solves the higher technical problem of releasing agent cost of the prior art.
The dryness releasing agent of a kind of injection industry of the present invention, is made up of the material of following percentage by weight:
Soybean emulsification honey 3 ~ 15%;
Polymeric methoxymethyl siloxanes (dimethicone) 0.3 ~ 1.0%;
107 silicon rubber 0.3 ~ 1.0%;
Benzinum (60 ~ 90) surplus.
Further, described polymeric methoxymethyl siloxanes is that 201-500cs silicone oil has another name called polydimethyl siloxane fluid, and its viscosity is 500cs.
Further, described soybean emulsification honey is the byproduct after the oil expression of soybean grease factory, and being usually used in food industry or feed industry, is main demoulding raw material.
Further, the chemical name of 107 described silicon rubber is hydroxyl endblocked polydimethylsiloxane.
Further, in described benzinum, the initial boiling point of cut is not less than 60 degrees Celsius, and the end point of distillation is not higher than 90 degrees Celsius.
Present invention also offers the preparation method of the dryness releasing agent of above-mentioned a kind of injection industry, comprise the steps: to take soybean emulsification honey, dimethyl silicone polymer, 107 silicon rubber, benzinum (60 ~ 90) according to mass ratio, first soybean emulsification honey is joined in benzinum, rapid stirring adds dimethyl silicone polymer and 107 silicon rubber again to dissolving completely, is stirred to and dissolves completely.
The present invention is that a kind of soybean emulsification honey that adopts is as the dryness releasing agent of primary raw material, because soybean emulsification honey molecular weight is not very big, can be dissolved in the organic solvents such as benzinum, after being sprayed onto metal die surface, solvent evaporates, leave the excellent and uniform organic polymer of thickness of one deck greasy property at die surface, separate plastics and iron and steel mould, make finished product be easy to deviate from from mould, and make plastic smooth surface, stop plastic products to be bonded on mould, play good stripping result.
The present invention compares with prior art, and its technological progress is significant.The present invention solves dryness releasing agent cost to remain high on the basis keeping dryness releasing agent premium properties, lacks the problem of price competitiveness.Solve soybean emulsification honey problem of outlet simultaneously, turn waste into wealth, reach green and produce.
