Embodiment 1

[0038] A kind of SAN resin composite material, comprises following component based on its gross weight:

[0039]

[0040]

[0041] The preparation method of this SAN resin composite material is as follows:

[0042] S1. SAN resin, PMMA resin, maleic anhydride-styrene binary copolymer, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, tri(2, 4-di-tert-butyl) phenyl phosphite and zinc stearate are poured into a medium-speed mixer and mixed uniformly to obtain a blend;

[0043] S2. Pour the blend into the storage hopper and extrude it through the twin-screw extruder. At the same time, the glass fiber is added from the natural exhaust port of the extruder, and the weight of the glass fiber entering the extruder per minute and the output per minute are tested. Calculate the weight of the finished product, calculate and control the glass fiber content, mix and extrude to obtain the SAN resin composite material.

Embodiment 2

[0045] A kind of SAN resin composite material, comprises following component based on its gross weight:

[0046]

[0047] The preparation method of this SAN resin composite material is as follows:

[0048] S1. SAN resin, PMMA resin, maleic anhydride-styrene binary copolymer, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, tri(2, 4-di-tert-butyl) phenyl phosphite and zinc stearate are poured into a medium-speed mixer and mixed uniformly to obtain a blend;

[0049] S2. Pour the blend into the storage hopper and extrude it through the twin-screw extruder. At the same time, the glass fiber is added from the natural exhaust port of the extruder, and the weight of the glass fiber entering the extruder per minute and the output per minute are tested. Calculate the weight of the finished product, calculate and control the glass fiber content, mix and extrude to obtain the SAN resin composite material.

Embodiment 3

[0051] A kind of SAN resin composite material, comprises following component based on its gross weight:

[0052]

[0053]

[0054] The preparation method of this SAN resin composite material is as follows:

[0055] S1. SAN resin, PMMA resin, maleic anhydride-styrene binary copolymer, tetrakis[β-(3,5-di-tert-butyl-4-hydroxyphenyl) propionate] pentaerythritol ester, tri(2, 4-di-tert-butyl) phenyl phosphite and zinc stearate are poured into a medium-speed mixer and mixed uniformly to obtain a blend;

[0056]S2. Pour the blend into the storage hopper and extrude it through the twin-screw extruder. At the same time, the glass fiber is added from the natural exhaust port of the extruder, and the weight of the glass fiber entering the extruder per minute and the output per minute are tested. Calculate the weight of the finished product, calculate and control the glass fiber content, mix and extrude to obtain the SAN resin composite material.

Abstract

The invention provides a solvent-resistant SAN resin composite material and a preparation method thereof. Based on the total weight, the SAN resin composite material comprises the following components: 42.4-58% of SAN resin, 18.5-21.5% of glass fiber, 20-30% of PMMA resin, 3-5% of a compatilizer, 0.2-0.6% of an antioxidant, and 0.3-0.5% of a lubricant. According to the SAN resin composite materialprovided by the invention, a certain amount of PMMA resin is mixed into an existing SAN resin and glass fiber reinforced material; the composite material has better solvent resistance; the problem that an existing AS-GF20 material is cracked when soaked in n-propyl alcohol and glacial acetic acid is effectively solved, cracking cannot occur after the AS-GF20 material is soaked in carbon tetrachloride, n-propyl alcohol and glacial acetic acid for a long time, and therefore the long-term use requirements of different types of air conditioner fan blades such as axial flow fan blades and centrifugal fan blades in the kitchen environment can be met.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a SAN resin composite material and a preparation method thereof. Background technique [0002] AS (SAN) resin belongs to styrene-based thermoplastic high-rigidity resin, which is generally prepared from acrylonitrile and styrene by bulk method, suspension method or emulsion method. It is usually used in the manufacture of housings for household daily necessities, including household electrical appliances, equipment accessories, auto parts, building materials, etc. Among them, the AS-GF20 material, which uses AS as the main base material and is mixed with glass fiber (GF) to enhance its mechanical properties, has the characteristics of high rigidity, high heat resistance, and high strength, so it is widely used in the manufacture of air conditioners, especially for air conditioners. Production of leaf parts. [0003] At present, major air conditioner manufacturers are ...
