preparation example Construction

[0031] The present invention provides a method for preparing the flame-retardant plastic-absorbing PC / ABS alloy material described in the above scheme, comprising the following steps:

[0032] 1) Mix and stir PC-122 and PA-1730 to obtain the first mixture;

[0033] 2) mixing and stirring the interface toughening compatibilizer, phosphazene flame retardant, plasticizing flame retardant synergist, anti-dripping agent, lubricant and antioxidant with the first mixture to obtain the total mixture;

[0034] 3) extrude the total mixture of the step 2) into granules, and cool to obtain a flame-retardant plastic-absorbing PC / ABS alloy material.

[0035] In the present invention, PC-122 and PA-1730 are mixed and stirred to obtain the first mixture. In the present invention, the rotational speed of the mixing and stirring is preferably 400-600 r / min, more preferably 500 r / min; the mixing and stirring time is preferably 3-5 minutes, more preferably 4 minutes.

[0036]After obtaining the...

Embodiment 1

[0041] 730Kg of PC-122 and 110Kg of PA-1730 were stirred at a speed of 400r / min for 5min to obtain the first mixture.

[0042] 30Kg interface toughening compatibilizer MBS 2620, 90Kg phosphazene flame retardant (PCTP), 25Kg triphenyl phosphate, 5Kg anti-dripping agent (entropy energy 3306), 4.5Kg lubricant (Tianjin Lianlong PETS) and 2.5 Kg antioxidant (Tianjin Lianlong 168) and the first mixture were mixed and stirred for 3min at a rotating speed of 2500r / min to obtain the total mixture;

[0043] The total mixture was extruded and granulated by a co-rotating twin-screw extruder (rotating speed 300r / min, temperature 265°C), and cooled in a water tank to obtain a flame-retardant and plastic-absorbing PC / ABS alloy material.

Embodiment 2

[0045] 740Kg of PC-122 and 90Kg of PA-1730 were stirred at a speed of 600r / min for 3min to obtain the first mixture.

[0046] 50Kg interface toughening compatibilizer MBS 2620, 70Kg phosphazene flame retardant (PCTP), 35Kg triphenyl phosphate, 3Kg anti-dripping agent (entropy energy 3306), 5.5Kg lubricant (Tianjin Lianlong PETS) and 1.5 Kg antioxidant (Tianjin Lianlong 168) and the first mixture were mixed and stirred for 2min at a rotating speed of 3500r / min to obtain the total mixture;

Abstract

The invention discloses a flame-retardant blister PC / ABS alloy material as well as a preparation method and application thereof, and belongs to the technical field of organic synthetic materials. Theflame-retardant blister PC / ABS alloy material comprises the following components in parts by weight: 73 to 74 parts of PC-122, 9 to 11 parts of PA-1730, 3 to 5 parts of an interface toughening compatilizer, 7 to 9 parts of a phosphonitrile flame retardant, 2.5 to 3.5 parts of a plasticizing flame retardant synergist, 0.3 to 0.5 part of an anti-dripping agent, 0.45 to 0.55 part of a lubricating agent and 0.15 to 0.25 part of an antioxidant. The plasticizing flame-retardant synergist is triphenyl phosphate or diphenyl phosphate. The PC / ABS alloy material provided by the invention is relatively good in comprehensive performance, relatively good in plastic uptake and high in saturation degree.

Description

technical field [0001] The invention relates to the technical field of organic synthetic materials, in particular to a flame-retardant plastic-absorbing PC / ABS alloy material and a preparation method and application thereof. Background technique [0002] Polycarbonate (referred to as PC) is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. PC has the advantages of high impact strength, good creep resistance and dimensional stability, heat resistance, and excellent dielectric properties, but also has disadvantages such as poor processing fluidity, easy stress cracking, sensitivity to notches, and poor chemical resistance. ABS resin is a terpolymer (acrylonitrile-butadiene-styrene) developed on the basis of polystyrene (PS) resin modification. It is a kind of good performance between engineering plastics and general-purpose p...
