Embodiment 1

[0023] A kind of preparation method of the nylon 6 composite material of high fluidity easy demoulding, comprises the following steps,

[0024] A, material preparation, including the following components by mass: injection molding grade nylon 675kg, EXPANCEL microsphere powder 5kg, calcium montanate 0.5kg, talcum powder 0.3kg, oleic acid 1kg;

[0025] EXPANCEL microsphere powder is AkzoNobel's EXPANCEL microsphere powder, and the model of the microsphere powder is 920DU20. Talc powder is made by mixing talc powder with a particle size of 1500 mesh and talc powder with a particle size of 800 mesh at a mass ratio of 4:6. Injection molding grade nylon 6 is selected from commercially available products.

[0026] B, mixing, the components in the step A are fully mixed to obtain a blend;

[0027] The components were mixed by a high-speed mixer for more than 20 minutes, and discharged at 60° C. for later use to obtain a blend.

[0028] C. Preparation: Extrude the blend in step B t...

Embodiment 2

[0031] The preparation method of this embodiment is basically the same as that of Example 1, except that, in this embodiment, the preparation step includes the following components in parts by mass:

[0032] Injection molding grade nylon 686kg, EXPANCEL microsphere powder 15kg, calcium montanate 2kg, talcum powder 1.4kg, oleic acid 2kg.

Embodiment 3

[0034] The preparation method of this embodiment is basically the same as that of Example 1, except that, in this embodiment, the preparation step includes the following components in parts by mass:

[0035] Injection grade nylon 678kg, EXPANCEL microsphere powder 9kg, calcium montanate 0.8kg, talcum powder 0.7kg, oleic acid 1.5kg.

Abstract

The invention belongs to the field of high-polymer composite materials, and relates to a high-flowability easy-demolding nylon 6 composite material and a preparation method thereof. The preparation method comprises the following steps: A. preparing the following components in parts by mass: 75-86 parts of injection-molding-grade nylon 6, 5-15 parts of EXPANCEL microsphere powder, 0.5-2 parts of calcium montanate, 0.3-1.4 parts of talcum powder and 1-2 parts of oleic acid; B. mixing: thoroughly mixing the components in the step A to obtain a blend; and C. preparation: extruding the blend in the step B through the head of an extruder, and granulating to obtain the high-flowability easy-demolding nylon 6 composite material. The composite material has the advantages of high flowability and easy demolding, and can be used for designing thinner parts, thereby saving the material.

Description

technical field [0001] The invention belongs to the technical field of organic polymer composite materials, and relates to a nylon 6 composite material with high flow and easy demoulding and a preparation method thereof. Background technique [0002] Nylon 6 has balanced strength, hardness and chemical corrosion resistance, and is currently one of the most productive varieties of polyamide plastics. Because nylon has excellent barrier properties, it is often used to prepare nylon containers or precision instrument parts, which also requires it to have good fluidity during processing; at the same time, nylon resins often suffer from excessive melt viscosity during processing. If it is too large, it will cause the product to be rough, lack luster, or have problems such as flow lines and glass fiber exposure. [0003] A Chinese invention patent discloses a high-fluidity nylon 6 and its manufacturing process [Application No.: 201210436753.8], which is composed of the following ...
