Problems solved by technology

However, the flame retardancy of this composite material is poor; for this reason, many plastic door and window manufacturers apply halogenated flame retardants to polycarbonate / ABS resin composite materials to improve their flame retardancy. The ecological requirements of the environment for materials are getting higher and higher, and the halogenated flame-retardant polycarbonate / ABS resin composite materials are increasingly criticized by people

preparation example Construction

[0016] figure 1 It is a process step chart of the preparation method of the new flame-retardant door and window profile in the embodiment of the present invention; the raw material components contained in the door and window profile include polycarbonate, ABS resin, MBS resin, composite flame retardant, and composite auxiliary agent. The preparation method The method includes the following steps: a) mixing raw materials, b) extrusion granulation, and c) injection molding.

[0017] The new flame-retardant door and window profiles mentioned in the present invention use polycarbonate / ABS resin composite plastic as the base material, and are prepared by adding composite flame retardant, compatibilizing and toughening agent and composite auxiliary agent, and adopting the method of melt blending and extrusion. become. Among them, the composite flame retardant is composed of bisphenol A bis(diphenyl phosphate) and potassium perfluorobutane sulfonate at a mass ratio of 120:1; the com...

Embodiment 1

[0019] The specific preparation method is as follows:

[0020] a) Mix raw materials, first weigh 78% polycarbonate, 10% ABS resin, 3% MBS resin, 8% composite flame retardant, 1% composite auxiliary agent by weight percentage; then put the above raw materials into Put it into a high-speed stirring container and mix evenly, wherein, the stirring speed is 500r / min, and the stirring time is 10min.

[0021] b) Extrusion granulation, put the mixed material prepared in step a) into a twin-screw extruder, and melt and extrude according to the extruder process conditions to obtain pellets; wherein, the extruder process conditions are: extruder The rotation speed is 40r / min, and the temperature of each section of the extruder is 200°C, 210°C, 220°C, and 210°C from the feed port to the die head.

[0022] c) Injection molding, first preheat the pellets prepared in step b) at 80°C for 2 hours, and then use the injection molding machine to inject the pellets according to the injection mold...

Abstract

The invention provides a novel flame-retardant door and window profile and a preparation method thereof. The door and window profile comprises polycarbonate, ABS (acrylonitrile butadiene styrene) resin, MBS (methacrylate butadiene styrene) resin, composite flame retardant and composite auxiliaries. The preparation method includes the steps: a) mixing raw materials; b) squeezing granulation; c) injection molding. The door and window profile has fine mechanical property, high heat resistance and excellent halogen-free flame retardation, and is extremely wide in application prospect.

Description

technical field [0001] The invention relates to a door and window profile, in particular to a novel flame-retardant door and window profile and a preparation method thereof, belonging to the technical field of doors and windows. Background technique [0002] Doors and windows are an indispensable part of the living room. Doors and windows can be divided into wooden doors and windows, steel doors and windows, aluminum alloy doors and windows, plastic doors and windows, etc. according to their materials. Among them, wooden doors and windows are moderate in price, poor in appearance, poor in sealing, afraid of fire and flammable, deformed and cracked, high in maintenance costs, and short in service life; steel doors and windows are low in price, low in grade, easy to corrode, easy to deform, high in maintenance costs, and long in service life. Short and facing elimination; aluminum alloy doors and windows are light in weight, durable, good in sealing performance, good in flame...
