Fireproof composite material

Abstract

The invention provides a fireproof composite material which comprises polycarbonate, a sulfonate fire retardant, and glass fibers as inorganic filling materials. The component ratio of the polycarbonate is 100 parts by weight; the component ratio of the sulfonate fire retardant is 0.1-5.0 parts by weight; and the component ratio of the glass fiber is 5-50 parts by weight. Therefore, the fireproof composite material provided by the invention has a thickness of 1.5-1.0 cm, and has a fireproof grade of UL 94 V0 when tested by a vertical combustion test. The fireproof material provided by the invention can maintain a fireproof grade of UL 94 V0 with a light-weight requirement being met; the adopted sulfonate fire retardant is an environment-friendly material, and can avoid environment pollution; the glass fibers are used as inorganic filling materials, which can enhance the rigidity and the dimension stability of the fireproof composite material.

Description

technical field [0001] The present invention relates to a polymer compound composition, more particularly, to a fireproof composite material made of a polycarbonate composition or a polycarbonate derivative composition. Background technique [0002] Most general thermoplastic materials (such as: polycarbonate) have good mechanical strength and can be used in many industries, such as: architectural decoration, vehicle interiors, and housings for electronic components or electrical appliances, and more and more products require Only with flame retardant characteristics can it comply with relevant fire regulations and pass certification. Moreover, the design attributes of more and more products are light, thin and short under the requirements of light weight. However, the thinner the finished product is, the more difficult it is to maintain good fire resistance. [0003] At present, in the known technology, such as U.S. publication patent specifications US6001921, US6117542, U...

AI Technical Summary

Problems solved by technology

[0004] Among them, the halogen-based and phosphorus-based flame retardant materials with added bromide cannot meet the requirements of TCO'99 certification during the production process. Lower heat deflection temperature of material and cause mold contamination

However, fireproof materials using melamine or aluminum hydroxide as flame retardants have problems such as high processing temperature and poor impact strength.
