Problems solved by technology

[0004] But these flame retardants also have many deficiencies: First, it is difficult to eliminate impurities in these flame retardants during the production process, such as antimony trioxide impurities containing heavy metals such as arsenic trioxide and lead, which are highly toxic to the human body and do not meet the national RoHS indicators Secondly, when PVC is burned, it is difficult to burn completely, and a large amount of carbon particles will be produced, which will be scattered in the gas to form black smoke accompanied by pungent harmful gas, causing difficulties in rescue and escape from the fire scene; more seriously, in order to obtain Sufficient flame retardant performance requires a high proportion of addition, which affects the mechanical properties of the material, thereby affecting the overall comprehensive performance of the material
[0013] In the above patents, there are two obvious shortcomings: first, most of the flame retardant and smoke suppression systems are compounded with one or more of antimony trioxide, aluminum hydroxide, and magnesium hydroxide, and the addition amount is large (50-75%), and need to introduce more other additives, which will affect the mechanical properties of the material, such as the rate of dimensional change after heating, Vicat softening point; second, the particle size grade of most additives selected is relatively large , and added directly to PVC for direct compounding, affecting compatibility with PVC

Abstract

The invention discloses a steel-plastic fireproof window profile with good processing performance and mechanical strength and excellent flame-retardant and smoke inhibition effects and a manufacturing method thereof. The steel-plastic fireproof window profile is prepared by compounding a PVC foaming body and a steel liner, wherein the PVC foaming body consists of PVC resin, a plasticizer, a thermal stabilizer, an impact modifier, a lubricating agent, an ultraviolet absorbent, titanium dioxide, a flame-retardant and smoke inhibition agent and a foaming agent; the flame-retardant and smoke inhibition agent consists of zinc stannate, alpha-ammonium octamolybdate, alpha-zirconium phosphate, quaternary phosphorus salt surfactant and the like; the steel-plastic high-flame-retardant fireproof door and window profile can be used for improving the flame-retardant and smoke inhibition efficiency of the flame-retardant and smoke inhibition agent so as to ensure that the PVC foaming body has excellent plasticity, is convenient for performing composite processing on the steel liner, can be used for improving the oxygen index and reducing the smoke density grade, and is suitable for being used as frames of partition glass curtain walls and doors and windows of large buildings.

Description

technical field [0001] The invention relates to a building material, in particular to a steel-plastic fireproof door and window profile made of PVC foam with flame-retardant and smoke-suppressing effects and a steel lining and a manufacturing method thereof. Background technique [0002] With the development of industry, plastics are more and more widely used in chemical industry, light industry, agriculture, building materials, electromechanical, textile and other industries, and the development of plastic molding and processing technology is becoming more and more rapid. Especially in recent years, the rise of steel-plastic co-extruded door and window profiles has made plastics more and more important in the construction industry. [0003] Polyvinyl chloride (PVC) is widely used in chemical industry, light industry, agriculture, building materials, electromechanical, textile and other industries because of its advantages of corrosion resistance, insulation, wear resistance...
