Polymethacrylate Co-extruded Composite Profiles
At present, the production of wood plastic composite decking material products, due to poor UV resistance, generally in the mixing process to add colour to solve the problem of poor weather resistance, but this method of production in the use of products in the process of its poor weather resistance and easy to fade problems still can not be a very good solution and become a bottleneck in the development of the industry.
The chemical name is polymethacrylate (PMMA, commonly known as acrylic), is a development and application of early important thermoplastic, with good chemical stability and weather resistance, and easy to dye, do not fade, processed products beautiful appearance. It is covered in the existing plastic wood profile, better to solve the existing profile fade, poor weather resistance.
Traditional garden timber (pure wood/anticorrosive wood) is always faced with the dilemma of unstable anti-ageing performance and short service life. Mouldy, discolored, broken and warped; Low cost, high maintenance. Replacement and maintenance costs within five years exceed the first investment; Less color change, less creativity. Single grain color or processed carbonized wood color is difficult to reflect the urban culture; Credit pressure. Landscape engineering many problems, let the government, users and landscape companies bear the credit crisis brought by materials.
The production process of the product, using two extruders, one for plastic wood base material, one for co-extrusion decking material, through the co-extruded composite profiles die at the same time, the molding can be one thickness of the fully coated plastic wood products. Products can be processed into a variety of products, such as the floor, bench bar, column and so on. This kind of product because has the coating layer structure, the ultraviolet ray resistance ability is strong, the mechanical strength is high, the chemical property is stable, the weather resistance is good, easy to dye, does not fade, greatly enhanced the existing plastic wood material service life, has opened up a brand-new direction for the plastic wood product outdoor use.
The co-extruded composite profiles product belongs to a new generation polymer composite material with very stable chemical and physical properties. Due to low resource consumption, pollution-free production, ecological and environmental protection, wide use and recycling, it is known as the most economical and useful new material invention in the 21st century. It is mainly used in building materials, landscape and other industries, and is an ideal material to replace traditional wood, plastic, stone, porcelain and calcium. It fully shows the composite advantages of stable structure, a combination of hardness and softness, and strong reprocessing performance, which significantly improves the ability of anti-ageing and anti-impact. It is an outdoor plate produced by using quartz plastic base material.
Plate inert, not easy to produce a chemical reaction, not warps, not cracking, acid and alkali resistance, corrosion resistance, non-toxic, odorless, no radiation, no long fungus, no mildew, co-extruded composite profiles is very ideal outdoor building materials. Plate internal molecular structure is dense, with high strength and impact resistance, its load force, deformation resistance, service life is much better than the traditional materials. In particular, it is good waterproof, soaking in water for a long time, no expansion, no deformation, especially suitable for coastal, southern city landscape, yacht dock and yard use.
It is easy to cut as a special kind of “wood” and then modular assembly with standard fasteners. The water absorption rate is only 0.2%, good water resistance, not easy to mildew, corrosion resistance, moth resistance, good chemical stability, high hardness, material texture strong, high surface hardness, not easy to wear, according to needs, make different colors. Good anti-ageing performance, long service life, outdoor decoration garden, landscape design, courtyard, floor, landscape chair, guardrail production, building curtain wall, etc.
