Embodiment 1

[0020] A high temperature resistant plastic bottle cap masterbatch. The components of the plastic bottle cap masterbatch include 85 parts by weight of low-density polyethylene resin, 3 parts of heat stabilizer, 2 parts of flame retardant, and 0.5 parts of dispersant. Parts, 0.5 parts of surface treatment agent, 6 parts of filling masterbatch.

[0021] Further, the components of the filler masterbatch include 30 parts by weight of the filler masterbatch carrier, 10 parts filler, 0.5 part dispersant, and 1.5 parts surface treatment agent. The function of the dispersant is to improve the processing fluidity of the masterbatch. , It is helpful for the masterbatch to be more uniformly dispersed in the matrix resin, and the surface treatment agent can change the surface activity of the inorganic filler, making it from hydrophilic to lipophilic, so as to facilitate mixing with the filler masterbatch carrier.

[0022] Further, the preparation method of the filling masterbatch includes the ...

Embodiment 2

[0033] A high temperature resistant plastic bottle cap masterbatch. The components of the plastic bottle cap masterbatch include 100 parts by weight of low-density polyethylene resin, 6 parts of heat stabilizer, 4 parts of flame retardant, and 2 parts of dispersant. Parts, 1 part of surface treatment agent, 10 parts of filling masterbatch.

[0034] Further, each component of the filler masterbatch includes 40 parts by weight of the filler masterbatch carrier, 20 parts of the filler, 1 part of the dispersant, and 2 parts of the surface treatment agent.

[0035] Further, the preparation method of the filling masterbatch includes the following steps:

[0036] (a) Take 40 parts of filler masterbatch carrier and 20 parts of filler into a mixer, heat to 50°C, and keep stirring for 20 minutes;

[0037] (b) Take 1 part of the dispersant and 2 parts of the surface treatment agent and place them in the above-mentioned mixer, and keep stirring for 30 minutes to make the mixing uniform to obtain ...

Embodiment 3

[0046] A high-temperature resistant plastic bottle cap masterbatch. The components of the plastic bottle cap masterbatch include 88 parts by weight of low-density polyethylene resin, 4 parts of heat stabilizer, 3 parts of flame retardant, and 1 part of dispersant. Parts, 0.7 parts of surface treatment agent, 8 parts of filling masterbatch.

[0047] Further, each component of the filler masterbatch includes 34 parts by weight of the filler masterbatch carrier, 16 parts of filler, 0.6 part of dispersant, and 1.7 parts of surface treatment agent.

[0048] Further, the preparation method of the filling masterbatch includes the following steps:

[0049] (a) Take 34 parts of filler masterbatch carrier and 16 parts of filler into a mixer, heat to 44°C and stir continuously for 17 minutes;

[0050] (b) Take 0.6 parts of dispersant and 1.7 parts of surface treatment agent and place them in the above-mentioned mixer, and keep stirring for 27 minutes to make the mixture uniform to obtain the req...

Abstract

The invention discloses a high temperature resistant plastic bottle cap masterbatch. The plastic bottle cap masterbatch includes the following components, by weight: 85-100 parts of low density polyethylene resin, 3-6 parts of a heat stabilizer, 2-4 parts of a flame retardant, 0.5-2 parts of a dispersant, 0.5-1 part of a surface treating agent, and 6-10 parts of a filling masterbatch. According tothe invention, the dispersant and the surface treating agent are added into the masterbatch raw materials to fully fuse the heat stabilizer and the flame retardant so as to improve the heat resistance of a plastic bottle cap. Meanwhile, the filling masterbatch is added into the masterbatch raw materials. The filling masterbatch can not only improve the heat resistance of the plastic bottle cap, but also improve the tensile strength and bending strength of the plastic bottle cap. Furthermore, a filling material is added into the filling masterbatch, and so the amount of the masterbatch raw materials can be increased and the cost of the raw materials is reduced. The plastic bottle cap produced by the masterbatch provided by the invention is high temperature resistant, does not deform in theprocess of high temperature disinfection, can improve the tensile strength and bending strength of the plastic bottle cap, and can reduce the cost of the raw materials.

Description

Technical field [0001] The invention relates to a high temperature resistant plastic bottle cap master batch and a manufacturing process thereof, and belongs to the technical field of plastic bottle caps. Background technique [0002] Plastic bottle caps are widely used in the packaging of food and medicines, and used with packaging bottles. Therefore, after the production of plastic bottle caps, they need to be sterilized by high temperature before they can be put into use. The general high temperature sterilization temperature is 121°C. However, the raw materials in the prior art produce plastic bottle caps that are not resistant to high temperatures and are easily deformed in a high-temperature environment, thereby affecting the sealing properties of the bottle caps and affecting the use. To this end, we propose a high temperature resistant plastic bottle cap master batch and its manufacturing process. Summary of the invention [0003] The main purpose of the present invention...
