Flame-retardant smoke-suppressant PVC (polyvinyl chloride) buckle plate and preparation method thereof

Abstract

The invention relates to a flame-retardant smoke-suppressant PVC (polyvinyl chloride) buckle plate and a preparation method thereof. Two ends of the flame-retardant smoke-suppressant PVC buckle plate are provided with a rabbet and a tenon which are matched with each other; and the flame-retardant smoke-suppressant PVC buckle plate is produced by mixing and extruding of the following raw materials in parts by weight: 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, 0.1-0.8 part of polyethylene wax and 4-30 parts of a flame-retardant smoke-suppressant system. The flame-retardant smoke-suppressant PVC (polyvinyl chloride) buckle plate and the production method thereof have the advantage of basically achieving the purposes of retarding flame and suppressing smoke by using less materials; and in addition, besides the characteristics of buckle plates including simplicity in mounting, more varieties, sound insulation, heat insulation, corrosion resistance, good comprehensive mechanical performance and the like, the flame-retardant smoke-suppressant PVC building form further the important advantages of good safety, good flame retardant performance and excellent smoke controllability.

Description

technical field [0001] The invention relates to a PVC gusset, in particular to a flame-retardant and smoke-suppressing PVC gusset 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 . With the development of society, people have become more and more strict on materials. Ordinary PVC gussets (Chinese invention patent, patent number: 200910100375.4) have g...

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
