preparation example Construction

[0026] A preparation method of the above-mentioned environment-friendly weather-resistant anti-aging flame retardant resin composition is characterized in that: it comprises the following preparation steps (such as figure 1 ):

[0027] First, add chlorinated polyethylene rubber grafted with butyl acrylate, styrene, and N-phenylmaleimide resin into the high-mixer and mix. The temperature is set at room temperature to 60°C. Plasticizer, continue mixing; when the temperature is 70°C-80°C, add antioxidant and lubricant; when the temperature is ≥80°C, add flame retardant, continue mixing, and cool and discharge when the temperature is ≤120°C;

[0028] Then, set the extrusion granulation temperature in the following sections: first section 160°C, second section 185°C, third section 200°C, fourth section 210°C, fifth section 200°C, sixth section 195°C , the seventh section is 205°C. The speed of the main machine is set at 250-300r / min; when the temperature reaches the set temperatu...

Abstract

The invention relates to an environmentally-friendly weather and aging resistant flame-retardant resin composition and a preparation method thereof. The composition comprises chlorinated polyethylene rubber grafted butyl acrylate, 100 parts by weight of styrene and an N-phenylmaleimide resin, 0.002-0.02 parts by weight of an antioxidant, 0.02-0.05 parts by weight of a plasticizer, 0.003-0.05 parts by weight of a lubricant and 0.02-0.15 parts by weight of a flame retardant. Technical problems comprising the material performance decrease and unsuitableness for the outdoor use caused by the addition of large amounts of expensive assistants comprising an environmentally-friendly flame retardant, an antioxidant, an ultraviolet ray absorber and the like to environmentally-friendly weather and aging resistant flame-retardant high-molecular materials in the prior art are solved in the invention. A Chinese blank is filled up, a foreign technological monopoly is broken through, and the high-molecular material which has the characteristics of weather resistance, ageing resistance, flame retardation and good comprehensive performances and can be used in the outdoor manner for a long term is provided in the invention. The composition has the advantages of simple and reasonable technical route, time saving, labor saving, environmental protection, mild technology, short production period, energy saving, consumption reduction, safety, and low production cost, and a cost 20-30% lower than an imported material.

Description

technical field [0001] The invention relates to a polymer material and a manufacturing method thereof, in particular to an environment-friendly, weather-resistant, aging-resistant, flame-retardant resin composition and a preparation method thereof. Background technique [0002] The materials used outdoors today are all energy-intensive non-renewable metals and woods, which are easy to rust and rot, and require painting and anti-corrosion treatment. However, the existing environment-friendly, weather-resistant, aging-resistant, and flame-retardant polymer materials basically use one or several types of polymer matrix resins to add a large number of expensive additives such as environmentally friendly flame retardants, antioxidants, and ultraviolet absorbers. Prepared by mixing granules. The addition of environmentally friendly flame retardants is very large, generally more than 20%, and the addition of a large amount of flame retardants will cause a decline in material perfo...
