Colored plastic wood composite materials make the world more colorful
With the rapid development of science and technology and the continuous improvement of people’s living standards, higher requirements have been placed on WPC, which not only requires materials to have good decorative effects, but also requires high cost performance. In order to meet these needs of consumers, WPC It will develop in the direction of high functionality and intelligence. Plastic wood itself does not have the characteristics of high functionality and intelligence, but an appropriate amount of functional pigments can be added to the material matrix to make plastic wood have certain special functions, such as anti-fouling, anti-mildew, fire prevention, temperature display and luminescence, etc. special function.
At present, there are relatively few studies on the application of functional pigments to plastic wood composite, which has a great development prospect. Scientists and technicians added color-changing capsules into bamboo powder/plastic composite materials, and successfully prepared reversible thermochromic plastic wood. At the same time, they studied the mechanical properties, physical properties, rheological properties, temperature and light response and thermal properties of the material. However, functional pigments are relatively expensive compared to organic and inorganic pigments, and they are more sensitive to environmental changes, which limits their application in plastic wood to a certain extent. In order to realize the functionalization and intelligence of plastic wood composite, it is necessary to strengthen the research and development of non-toxic or low-toxicity, environmentally friendly functional pigments, while ensuring the functionality of the materials, minimize the production cost of functional pigments.
As a new green and environmentally friendly material, plastic wood composite has a very good development prospect, and has been widely used in outdoor, automotive interior and construction fields. In order to produce colored plastic wood composite with excellent performance and high degree of functionality, materials must be strictly selected according to the type of material, physical and chemical properties, and the process parameters must be reasonably adjusted according to the ratio of materials and the environmental conditions of the place of use. Under the premise, add appropriate pigments.
Studies have found that by adding functional pigments to the plastic wood composite matrix, not only will not cause significant damage to the strength of the plastic wood composite, but also has a good decorative effect, environmental protection and low or non-toxic to humans, allowing the material to have certain special functions , which enhances the added value of materials, and promotes the development of the plastic wood industry in the direction of functionalization and intelligence.
