Problems solved by technology

[0005] At present, the masterbatches on the market use oleic acid amide or erucic acid amide, as well as talcum powder, silicon dioxide, ultrafine calcium carbonate and barium sulfate in the preparation process, so that the prepared masterbatches have a certain Color, large amount added, poor hand feeling
In addition, the masterbatch made of oleic acid amide or erucic acid amide should generally be used at a temperature not higher than 260°C, and its high temperature resistance is poor; and its migration range is too large
[0006] At present, oleic acid amide and erucic acid amide are gener

Embodiment 1

[0024] The invention discloses a high-temperature-resistant, low-migration organic slippery opening agent, which is obtained by mixing 25% by weight of pentaerythritol stearate, 25% by weight of ethylene bisoleic acid amide and 50% by weight of behenic acid amide.

[0025] The anti-blocking agent can be used alone as a masterbatch, and the method for making the anti-blocking agent into a carrier-free, high-temperature-resistant, low-migration organic slippery anti-blocking agent masterbatch is as follows:

[0026] 1. Extrusion method: Mix the components and feed them into the screw extruder, extrude and cut into pellets to obtain carrier-free, high-temperature-resistant, low-migration organic smooth open masterbatch. The obtained masterbatch can withstand high temperature 350°C , and dispersed well, no migration.

[0027] 2. Dropping bead granulation method: Mix and heat the components to 120 degrees to dissolve, then cool down to 90 degrees and stir for 20 minutes, then filte...

Abstract

The invention discloses a heat-resistant and low-migrating organic smooth opening agent which is obtained by mixing of, by weight, 25-50wt% of component A, 25-50wt% of component B and 25-50wt% of component C. The component B refers to pentaerythritol fatty acid ester, the component B refers to one or two selected from ethylene bis oleamide and stearyl erucic acid amide, and the component C refers to one or two selected from behenamide and polymethyl methacrylate; ethylene bis oleamide and stearyl erucic acid amide are in the mass ratio of 2:1-1:2 when used simultaneously; behenamide and polymethyl methacrylate are in the mass ratio of 2:1-1:2 when used simultaneously. A carrier-free opening-agent master batch obtained with the above formula has the advantages of smoothness, opening, lubricating, demolding and no folding out of the surface in plastics, and the opening agent is resistant to high temperature to 350DEG C, low in migration and uniform in dispersion and is used for preparing the heat-resistant and smooth plastic master batch.

Description

technical field [0001] The invention relates to the technical field of preparation of plastic masterbatches, more specifically, to a high-temperature-resistant, low-migration organic slippery anti-blocking agent and a masterbatch prepared from the anti-blocking agent. Background technique [0002] Plastic raw materials can only be made into plastic materials through processing. The most commonly used methods for forming (thermoplastic) under high temperature conditions are extrusion, injection molding, calendering, casting, blow molding, blister and thermoforming. Plastic materials have the advantages of light weight, high strength, excellent electrical properties, easy processing and molding, and bright colors, so they have become the most active field of material systems, and their applications in other fields are also expanding. From people's daily necessities, medical , agriculture and fishery, automobile, electrical and chemical construction, defense industry, aerospace...
