Problems solved by technology

[0005] Chinese patent document CN 104177685 A provides a black nylon 6 plastic containing iron chromium oxide as an infrared reflector, but only contains one infrared reflector, and the content is limited to 0.5-1.5%
[0010] 1. There is no COC plastic with infrared heat insulation;
[0011] 2. The existing infrared reflective plastic color matching space is relatively narrow, and can only achieve green, blue, brown, black, gray and other hues, but cannot achieve purple, yellow and other colors
[0012] 3. Although infrared reflective pigments can reflect infrared rays to achieve heat insulation, they cannot prevent the degradation of plastics caused by ultraviolet light

Abstract

The invention discloses an infrared light reflection heat insulation COC plastic and a preparation method and application thereof. The COC plastic is prepared from the following raw materials in percentage by weight: 50 to 99.5 percent of COC, 0.5 to 50 percent of infrared reflecting agent, 0 to 1 percent of antioxidant, 0 to 1 percent of UV (Ultraviolet) stabilizer and 0 to 10 percent of titanium dioxide. The infrared reflecting agent comprises at least one of pigment blue 28, pigment blue 36, pigment green 50, pigment green 60, pigment yellow 53, pigment brown 24, pigment brown 33, pigment yellow 164, pigment green 17, pigment brown 29, pigment black 30, pigment purple 16 and pigment purple 14. The preparation method comprises the following steps: uniformly mixing the raw materials according to the ratio, adding the mixture into a double-screw extruder through a main feeding port, and conducting extruding to obtain the infrared light reflection heat insulation COC plastic. When the COC plastic is applied to a packaging material, a packaged object can be prevented from deteriorating due to rapid temperature rise, and the COC plastic is particularly suitable for packaging temperature-sensitive components, raw materials and other products.

Description

technical field [0001] The invention relates to the field of COC plastics, in particular to an infrared light reflective heat-insulating COC plastic and a preparation method and application thereof. Background technique [0002] As a multifunctional packaging material, cycloolefin copolymer (COC) resin is widely used in many fields due to its excellent properties such as water vapor barrier. However, infrared light can penetrate ordinary COC resin, and solar radiation will cause the packaged items to heat up rapidly and deteriorate. [0003] Infrared reflective heat insulation technology is generally applied to coatings, but for packaging materials, coating coating involves secondary processing, which will increase man-hours and costs. Therefore, the infrared reflective modified COC resin can be used as a packaging material, which can avoid secondary processing, save man-hours, and save costs. [0004] The following are some existing infrared reflective plastic inventions....
