Embodiment 1

[0054] The acrylonitrile-butadiene-styrene foamed plastic formula without irritating smell is composed of the following components by weight percentage:

[0055] Acrylonitrile-butadiene-styrene 95%;

[0056] AC foaming agent 3%;

[0057] Diffusion agent EB-FF 1%;

[0058] Antioxidant 1010 0.3%;

[0059] Antioxidant 168 0.2%; and,

[0060] Purified biological enzyme enzyme (pumpkin vine biological enzyme enzyme) 0.5%; the enzyme product made from pumpkin vine as raw material is commercially available, such as the 601 type enzyme produced by Shanghai Qianbao Fine Chemical Co., Ltd.;

[0061] The sum of the above ingredients is 100%.

[0062] Preparation:

[0063] Step S1, weigh according to the above-mentioned foamed plastic formula, and put acrylonitrile-butadiene-styrene, diffusing agent EB-FF, antioxidant 1010, antioxidant 168 and purified biological enzymes in a mixer for mixing (AC blowing agent is not added here), forming a mixture;

[0064] Step S2, mixing the mixt...

Embodiment 2

[0071] The acrylonitrile-butadiene-styrene foamed plastic formula without irritating smell is composed of the following components by weight percentage:

[0072] Acrylonitrile-butadiene-styrene 96%;

[0073] AC foaming agent 2%;

[0074] Diffusion agent EB-FF 1%;

[0075] Antioxidant 1010 0.25%;

[0076]Antioxidant 168 0.25%; and,

[0077] Purified bio-enzyme (pumpkin vine bio-enzyme) 0.5%;

[0078] The sum of the above ingredients is 100%.

[0079] The preparation method is the same as in Example 1.

[0080] Performance characteristics: irritating odor, extremely slight.

Embodiment 3

[0082] The acrylonitrile-butadiene-styrene foamed plastic formula without irritating smell is composed of the following components by weight percentage:

[0083] Acrylonitrile-butadiene-styrene 90.5%;

[0084] AC foaming agent 5%;

[0085] Diffusion agent EB-FF 3%;

[0086] Antioxidant 1010 0.5%;

[0087] Antioxidant 168 0.5%; and,

[0088] Purified bio-enzyme (pumpkin vine bio-enzyme) 0.5%;

[0089] The sum of the above ingredients is 100%.

[0090] The preparation method is the same as in Example 1.

[0091] Performance characteristics: irritating odor, slight.

[0092] Thus, embodiment 1 is better than embodiment 2, and embodiment 2 is better than embodiment 3 again. The reason is that the weight percent sum of antioxidant 1010 and antioxidant 168 in embodiments 1 and 2 is equal to the weight percent of purified biological enzyme ferment, and the antioxidant 1010 and antioxidant 168 of embodiment 3 The sum of the weight percentages is far greater than the weight per...

Abstract

The invention discloses a formula and a preparation method of a pungent-smell-free acrylonitrile-butadiene-styrene foamed plastic, wherein the pungent-smell-free acrylonitrile-butadiene-styrene foamedplastic comprises the following components by weight: 90.5-96% of acrylonitrile-butadiene-styrene, 2-5% of an AC foaming agent, 1-3% of a dispersing agent EB-FF, 0.05-0.5% of an antioxidant 1010, 0.05-0.5% of an antioxidant 168, and 0.1-0.5% of purified biological enzyme. The finished product has no obvious pungent smell, the influence on injection molding operators is eliminated, the quality grade of the product is improved, and the competitiveness is high.

Description

technical field [0001] The invention relates to the field of plastic formulations, in particular, acrylonitrile-butadiene-styrene foamed plastic formulations without pungent odor. Background technique [0002] Acrylonitrile-butadiene-styrene, English name: Acrylonitrile Butadiene Styreneplastic, abbreviation: ABS. [0003] AC foaming agent, the chemical name is azodicarbonamide, the English name is Azobisformamide or Azodicarbonamide, ABFA, ADCA. [0004] Acrylonitrile-butadiene-styrene and AC foaming agent are mixed for foaming injection molding. The disadvantage is that: the decomposition and shearing of acrylonitrile-butadiene-styrene will produce HCN (hydrogen cyanide) during the injection molding process. ) and NOx (nitrogen oxides), styrene monomer, butadiene monomer, phenol and other gases form a unique odor; due to the exothermic action of the AC foaming agent, the small molecular organic matter, CO 2 , SO 2 , Ammonia (NH 3 ) and other decomposition, precipitatio...
