Description
Technical Field
The invention relates to the technical field of section bar preparation, in particular to a polyvinyl chloride section bar with high flame retardance and photooxidation aging resistance and a preparation method thereof.
Background
The PVC profile is an industrial and domestic PVC product which is formed by adding various functional additives into PVC resin and then extruding at high temperature, and can be divided into hard PVC profile and soft PVC profile according to the performance, wherein the hard PVC profile is mainly used for building aspects, such as manufacturing PVC doors and windows, PVC bottom plates, PVC pipes and the like; the soft PVC section bar is used for manufacturing PVC hoses, transmission cables and the like. The PVC section added with the functional auxiliary agent has the advantages of ageing resistance, ultraviolet resistance, corrosion resistance, high strength, low price and good heat preservation and heat insulation performance, can partially replace materials such as aluminum sections, steel and the like, and has lower pollution degree than aluminum sections.
The PVC profile product undergoes the lead-in period and the high-speed development period, and as one of products of scientific and technological development, the PVC profile is rapidly developed in the field of doors and windows, and a wide space is provided for the development of the national building material industry.
However, polyvinyl chloride sectional materials and doors and windows produced by various domestic manufacturers are generally conventional sectional materials, have poor flame-retardant and fireproof performance, are easy to cause hidden trouble accidents, have poor effect on solving the problem of photo-oxidative aging of the PVC sectional materials, influence the service life of the door and window sectional materials, and particularly have more obvious influence in certain strong-light areas.
Disclosure of Invention
The technical problem to be solved by the invention is as follows:
the existing polyvinyl chloride sectional material is poor in flame-retardant and fireproof performance, is easy to cause hidden trouble accidents, and solves the problem that the PVC sectional material is poor in photo-oxidative aging effect, so that the service life of the door and window sectional material is influenced.
The invention adopts the technical scheme for solving the technical problems that:
the high-flame-retardant photo-oxidation-aging-resistant polyvinyl chloride profile is prepared from the following raw materials in parts by mass: 85-95 parts of polyvinyl chloride, 10-15 parts of inorganic flame retardant, 5-10 parts of organic flame retardant, 2-4 parts of heat stabilizer, 0.1-0.5 part of lubricant, 15-20 parts of impact modifier, 1-3 parts of titanium dioxide, 1-3 parts of ultraviolet absorbent, 6-9 parts of antioxidant and 0.2-0.4 part of fluorescent brightener;
