Flame-retardant and smoke-suppression PVC building template and fabrication method thereof

Abstract

The invention relates to a flame-retardant and smoke-suppression PVC (polyvinyl chloride) building template and a fabrication method thereof. The flame-retardant and smoke-suppression PVC building template is combined integrally by a panel, a connecting partition and a reinforcing rib plate, and is characterized in that the panel, the connecting partition and the reinforcing rib plate of the PVC building template are fabricated by the following raw materials in parts by weight through mixing and extrusion: 100 parts of PVC resin, 5-40 parts of calcium carbonate, 4-8 parts of heat stabilizer, 1-5 parts of processing aid ACR (acrylics), 5-10 parts of impact modifier CPE (chlorinated polyethylene), 0.5-10 parts of pigment, and 4-30 parts of flame-retardant and smoke-suppression system. The flame-retardant and smoke-suppression PVC building template and the fabrication method have the advantages that flame retardance and smoke suppression purposes are achieved basically by using fewer materials; in addition, the flame-retardant and smoke-suppression PVC building template has the characteristics that the flame-retardant and smoke-suppression PVC building template is simple and convenient to mount, various in assortment, sound-proof, heatproof, corrosion-resistant, and good in comprehensive mechanical property; and the flame-retardant and smoke-suppression PVC building template has the most important advantages of safety, good flame resistance and excellent smoke control property.

Description

technical field [0001] The invention relates to a PVC building template, in particular to a flame-retardant and smoke-suppressing PVC building template and a preparation method thereof. Background technique [0002] Polyvinyl chloride (PVC) is one of the five general-purpose plastics, and it is widely used in various fields because of its excellent performance-price ratio. In recent years, as the country vigorously promotes the tendency of replacing steel with plastic and wood with plastic, PVC as a chemical building material has developed rapidly. However, PVC is a flame retardant material, but due to the need to add plasticizers during processing, the flammability of PVC is improved, and a large amount of smoke will be generated when its products are burned, which increases the harm of fire to people's lives and property . [0003] Chinese invention patent application (application number: 201110307136.3 application date: 2011-10-12) discloses a combined PVC building form...

AI Technical Summary

Problems solved by technology

However, the addition of flame retardant and smoke suppressant will affect the mechanical properties of PVC materials, the greater the amount added, the greater the impact

In addition, some flame retardants and smoke suppressants have a great impact on PVC processing technology, and proper processing technology must be adjusted to normal production

At the same time, the production cost of some flame-retardant and smoke-suppressing products is very high, which requires us to not only achieve the effect of flame-retardant and smoke-suppressing, but also consider that the overall cost of the product should not be too high, choose the right product and the right dosage
