Problems solved by technology

Especially the plastic profiles and pipes located on the outer surface of the building, the accumulation of dust and the stains left by the rainwater washing will inevitably affect the appearance of the building after a certain period of time; at the same time, the water droplets remaining for a long time wet the surface of the building materials, increasing the surface Humidity, under certain conditions, will also accelerate the aging of materials and reduce the service life of building materials
The building materials located on the inner surface of the building also have the same problem, for example, the doors and windows will also leave water and dust stains after cleaning

preparation example Construction

[0014] The present invention provides a kind of preparation method of modified acrylonitrile-styrene-acrylate terpolymer resin, wherein, the method comprises the following steps:

[0015] 1) Under the conditions of the ammonolysis reaction, the acrylonitrile-styrene-acrylate terpolymer resin is first contacted with diamine to obtain the contacted acrylonitrile-styrene-acrylate terpolymer resin;

[0016] 2) Under the reaction conditions for generating amides, the contacted acrylonitrile-styrene-acrylate terpolymer resin obtained in step 1) is subjected to a second contact with the alkyl carboxylic acid solution;

[0017] Wherein, the diamine is a structure shown in formula (I), and R in formula (I) is C 1-20 A straight-chain or branched alkylene group, or an arylene group; the number of carbon atoms in the alkyl carboxylic acid is 3-30;

[0018] NH 2 -R-NH 2 (Formula I).

[0019] According to the method of the present invention, the acrylonitrile-styrene-acrylate terpol...

Embodiment 1

[0039] The ASA resin raw material (ASA resin raw material purchased from Sabic Company) was ultrasonically cleaned with water, and immersed in a methanol solution of p-phenylenediamine at 20°C (p-phenylenediamine:methanol=1:3 (volume ratio)) for 3h, After taking out, adopt methanol rinse after 3 times, dry under the temperature of 25 ℃, then the n-hexane solution (the content of capric acid is 1% by weight of the ASA resin of drying in 25 ℃ of capric acid, this capric acid Containing 0.5gDCC in the normal hexane solution) after soaking in 48h, take out, remove solvent and promptly obtain the modified ASA resin. After the modified ASA resin was dried, it was compression-molded to obtain a 2mm thick ASA disc (disc diameter 10cm, the same below), and the contact angle between the original ASA disc and pure water was measured to be 95-110°.

Embodiment 2

[0041] The ASA resin raw material (ASA resin raw material purchased from Sabic Company) was ultrasonically cleaned with water, immersed in a 25°C ethanol solution of hexamethylenediamine (hexamethylenediamine:ethanol=1:8 (volume ratio)) for 5h, and after taking it out , after adopting ethanol rinse 3 times, dry at a temperature of 25°C, then dry the ASA resin in the ethanol solution of tetracosanoic acid at 50°C (the content of tetracosanoic acid is 5% by weight) Take it out after submerging in the water for 30 hours, and remove the solvent to obtain the modified ASA resin. After the modified ASA resin was dried, it was compression-molded to obtain a 1mm-thick disc, which was cleaned by ultrasonic waves, and its contact angle with pure water was measured to be 100-120°.

Abstract

The invention provides a modification method of an acrylonitrile-styrene-acrylate terpolymer resin, which comprises the following steps: under ammonolysis reaction conditions, carrying out first contact on the acrylonitrile-styrene-acrylate terpolymer resin with diamine to obtain the contacted acrylonitrile-styrene-acrylate terpolymer resin; and under amide generation reaction conditions, carrying out second contact on the contacted acrylonitrile-styrene-acrylate terpolymer resin with an alkyl carboxylic acid solution. The invention also provides a modified acrylonitrile-styrene-acrylate terpolymer resin obtained by the method and a product prepared from the modified acrylonitrile-styrene-acrylate terpolymer resin. The modified acrylonitrile-styrene-acrylate terpolymer resin provided by the invention has excellent self-cleaning function.

Description

technical field [0001] The invention relates to a method for modifying acrylonitrile-styrene-acrylate terpolymer resin and the modified acrylonitrile-styrene-acrylate terpolymer resin prepared by the method and modified propylene A product prepared from a nitrile-styrene-acrylate terpolymer resin. Background technique [0002] Acrylonitrile-styrene-acrylate terpolymer (hereinafter referred to as ASA) combines the chemical resistance and high hardness of acrylonitrile with the impact resistance and weather resistance of acrylate , The excellent processing performance of styrene is integrated, and it is an engineering plastic with excellent comprehensive performance. ASA resin has been widely used in various chemical building materials because of its good colorability, rich colors, excellent weather resistance, and its Vicat softening temperature is as high as 92°C. In recent years, with the acceleration of urbanization and the continuous advancement of technology, a new gen...
