Problems solved by technology

However, the current commercialized thermosetting powder coatings do not have the function of self-degradation, so they will pollute the environment, especially for products with short service life and high replacement frequency, such as glass wine bottles, the pollution is more serious; Further, during the normal use of these products, it is more necessary to ensure that the products will not be degraded. Therefore, if you want to avoid the environmental pollution caused by the coating of powder coating glass wine bottles, you need to obtain a product that will not automatically degrade within the use cycle, but After reaching the service life, the product can be automatically degraded when certain environmental conditions are met

Abstract

The invention discloses a glass bottle coating with a degrading function and a glass bottle. A thermosetting powder coating is sprayed on the glass bottle and cured to obtain the glass bottle coating, wherein the thermosetting powder coating comprises the following raw materials in parts by weight: 25-55 parts by weight of thermosetting resin, 4-20 parts by weight of curing agent, 15-50 parts by weight of degrading agent, 0.1-5 parts by weight of flatting agent and 5-20 parts by weight of pigment and filler. According to the glass bottle coating, on the premise of meeting the basic performance of the glass bottle coating, a better degrading function of the glass bottle coating is effectively realized, and environment pollution caused by a wasted glass bottle is avoided.

Description

technical field [0001] The invention relates to a glass wine bottle coating, in particular to a glass wine bottle coating and a glass wine bottle with degradation function. Background technique [0002] Thermosetting powder coatings are widely used in various fields due to their advantages of no organic solvent, good environmental protection, high utilization rate, and convenient storage and transportation. Consumers hope that the coating of glass wine bottles coated with thermosetting powder coatings can be automatically degraded after the service life is met, so as to avoid environmental pollution caused by waste glass wine bottles and improve environmental protection performance. However, the current commercialized thermosetting powder coatings do not have the function of self-degradation, so they will pollute the environment, especially for products with short service life and high replacement frequency, such as glass wine bottles, the pollution is more serious; Further...
