Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with specific embodiments, and it cannot be assumed that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.

[0022] Implementation column 1

[0023] The steps of this embodiment are as follows:

[0024] S1. Disperse nano-cerium oxide in toluene solvent, configure the mixed dispersion liquid with a mass fraction of 20%, put it into the grinder, add 3% nano-cerium oxide dispersant BYK164, and grind it through a high-speed grinder until the particle size is about 50nm , stop grinding, and discharge to obtain a nano-slurry with a solid content of 20%.

[0025] S2, 25 parts of nano-c...

Abstract

The invention discloses an ultraviolet ray total barrier master batch and a preparation method thereof. The ultraviolet ray total barrier master batch comprises the following raw materials in parts byweight: 70-90 parts of a carrier resin polyethylene terephthalate (PET), 5-10 parts of ultraviolet absorbent, 1-5 parts of dispersant, 1-3 parts of antioxidant. The PET masterbatch is added into thePET product and thus the ultraviolet blocking rate of obtained PET product is more than 99.9%, and for thin film products, the light transmittance of the film product can reach 80-90%, the film product has full ultraviolet barrier, high light transmittance, high weather resistance, and a certain degree of thermal insulation. The PET masterbatch can be used as additive and directly used for manufacturing of the PET products, the properties of the PET products in terms of ultraviolet light barrier, transmittance, and the like can be conveniently adjusted by adjusting the composition, the addition amount, and the like of the masterbatch of the present invention, thereby expanding the application field of the PET products.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an ultraviolet total barrier masterbatch and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to their own health. Ultraviolet rays in sunlight are an inevitable thing that affects people's health. Therefore, effectively reducing the impact of ultraviolet rays on people's health is more and more popular. Therefore, most film or sheet products used outdoors need to block ultraviolet rays, especially window films used on glass and car windows. At present, many ultraviolet shielding films are mainly produced by coating, which has problems such as easy peeling off of the coating, high production cost, and large pollution. [0003] Preparing the ultraviolet blocking masterbatch first can better solve the problems existing in the traditional coating method, but in the process of ...
