Embodiment 1

[0028] The invention provides the following technical solutions:

[0029] A highly transparent modified nano-calcium masterbatch, the nano-calcium masterbatch includes the following raw material formula in parts by weight: 70 parts of nano-calcium, 6 parts of low fat-soluble high pressure, 3 parts of high fat-soluble high pressure, 2 parts of low melting point dispersant, Zinc stearate 1 part.

[0030] In a specific embodiment of the present invention, by putting nano-calcium and low-melting-point wax into a high-speed mixer at the same time for stirring, the nano-calcium powder is coated at the initial stage, so that it does not oxidize and burn at high temperature during processing. ;By using wax that melts at low temperature, the nano-calcium powder can be coated, and it is not easy to burn the calcium powder that is not coated with wax after heating up, so that the burned material is not easy to turn yellow; through the corresponding application carrier Resin extrusion gr...

Embodiment 2

[0048] A highly transparent modified nano-calcium masterbatch, the nano-calcium masterbatch includes the following raw material formula in parts by weight: 72 parts of nano-calcium, 7 parts of low-fat-melting high-pressure, 4 parts of high-fat-soluble high-pressure, 3 parts of low-melting wax, hard Zinc fatty acid 1.3 parts.

[0049] A method for preparing a highly transparent modified nano-calcium masterbatch, comprising the steps of:

[0050] S1: First select the wax that melts at low temperature, then put the nano-calcium and low-melting point wax into the high-speed mixer at the same time, and stir at a speed of 1200r / min for 5-15min, wait until the nano-calcium and low-melting point wax are mixed and heated to 105 degrees It can be stopped, and at this time, component A is obtained for use;

[0051] S2: After dehydrating the component A at 105 degrees, add low fat-melting high pressure, high fat-melting high pressure, low melting point wax and zinc stearate to the high-s...

Embodiment 3

[0055] A highly transparent modified nano-calcium masterbatch, the nano-calcium masterbatch includes the following raw material formula in parts by weight: 75 parts of nano-calcium, 8 parts of low-fat-soluble high-pressure, 5 parts of high-fat-soluble high-pressure, 4 parts of low-melting point wax, hard Zinc fatty acid 1.5 parts.

[0056] A method for preparing a highly transparent modified nano-calcium masterbatch, comprising the steps of:

[0057] S1: First select the wax that melts at low temperature, then put the nano-calcium and low-melting point wax into the high-speed mixer at the same time, and stir at a speed of 1200r / min for 5-15min, wait until the nano-calcium and low-melting point wax are mixed and heated to 105 degrees It can be stopped, and at this time, component A is obtained for use;

[0058] S2: After dehydrating the component A at 105 degrees, add low fat-melting high pressure, high fat-melting high pressure, low melting point wax and zinc stearate to the ...

Abstract

The invention provides high-transparency modified nano calcium masterbatch, and belongs to the technical field of nano calcium masterbatch. The high-transparency modified nano calcium masterbatch comprises the following raw materials in parts by weight: 70-85 parts of nano-calcium, 6-12 parts of a low-fat-solubility high pressure material, 3-9 parts of a high-fat-solubility high pressure material,2-8 parts of low-melting-point wax, and 1-3 parts of zinc stearate. According to the masterbatch, the production cost is low, so that the nano calcium masterbatch has the advantages of fine and smooth product surface, uniform dispersion, high whiteness, particularly good optical transparency and the like in the plastic industry; as a filling body, the masterbatch has the characteristics of largevolume, good tensile force, excellent impact resistance and the like; the masterbatch can be widely applied to various processing technologies of plastics, such as injection molding, film blowing, tape casting, calendering, extrusion and the like, can also be applied to production of various types of functional masterbatch, and has a wide market.

Description

technical field [0001] The invention belongs to the technical field of nano-calcium masterbatch, and in particular relates to a highly transparent modified nano-calcium masterbatch. Background technique [0002] The masterbatch is a resin component or base material in which fibers or other reinforcing materials are dispersed in reinforced plastics. The continuous phase in composite materials is called masterbatch or base material. [0003] At present, all filler masterbatches on the market in our country are made of low-mesh (400-2500 mesh) heavy calcium powder as raw materials. The transparency of blown film products is poor, and this kind of filler masterbatch can be used in plastic processing. The filling amount is low; and the production cost is high, the tensile force is poor, and the impact resistance is weak. Contents of the invention [0004] The purpose of the present invention is to provide a highly transparent modified nano-calcium masterbatch, which aims to s...
