Abstract

The invention discloses a modified PP flame-retardant material air-conditioner plastic suction thermal-insulation plate, which comprises, by weight, 50-70 parts of polypropylene, 30-50 parts of high-density polyethylene, 10-20 parts of a flame retardant, 0.3-1 part of an anti-aging agent, 2-5 parts of a synergist, and 0.5-1 part of a stabilizer, wherein the synergist is the compound of graphite, phosphoenolpyruvate and pyridoxal 5-phosphate, the stabilizer is sodium octyl phosphate, and the flame retardant is potassium hexatitanate crystal whisker. According to the present invention, the preparation is performed by mainly using polypropylene and high-density polyethylene as the basic materials, and potassium hexatitanate is added, such that the flame retardancy of the whole material can besubstantially improved; and the added synergist can provide good flame retardant performance, and can make the whole material can have good mechanical property in an annealed state for a long time.

Description

technical field [0001] The invention relates to a polymer material, in particular to a PP antibacterial film and a preparation method thereof. Background technique [0002] Polypropylene (PP) is widely used in electronic appliances, communication equipment, automobiles, building materials and other fields due to its advantages of low price, excellent mechanical properties, and easy molding and processing. However, due to the flammability of PP itself, its further application is limited. Although traditional halogen-containing flame retardants have good flame-retardant properties, they will produce a lot of smoke and toxic gases when they burn, causing secondary pollution. Therefore, it is of great significance to study halogen-free flame-retardant polypropylene. [0003] Flame-retardant insulation panels are often used in air conditioners. During the operation of the air conditioner, due to heat exchange, a continuous and stable temperature is generated. This temperature is...
