Embodiment 1

[0021] A low-cost black plastic, which is composed of the following raw materials in parts by weight:

[0022] Lanolin 2, myristyl oleate 6, barium metaborate 0.7, zinc cyanurate 0.2, phthalate 12, bis-octylmethyl tertiary amine 0.2, ammonium polyphosphate 106, glacial acetic acid 1.3, ethyl Base cellulose 1.3, tetraethyl orthosilicate 3, dodecafluoroheptylpropyltrimethoxysilane 20, 95% ethanol 34, 0.5mol / l aniline aqueous solution 200, sodium peroxide 10, polyvinyl chloride 500, Fly ash 5, carbon black 2.

[0023] A preparation method of low-cost black plastic, comprising the following steps:

[0024] (1) Calcinate the fly ash at 800°C for 1 hour, and after the discharge is cooled, put it into a 14mol / l sodium hydroxide solution to soak for 3 hours, filter it, wash it with water, mix it with lanolin, and add it to the mixture with a weight of 3- Add myristyl oleate to 4 times of absolute ethanol, heat and stir at 70°C for 10 minutes to obtain pretreated fly ash;

Abstract

The invention discloses low-cost black plastic. A sol-gel treatment process is adopted to coat the surface of APP (ammonium polyphosphate) firstly to improve the surface strength and water resistance, then polyaniline coating is performed to improve the flame retardance and thermal decomposition, and the dispersity and compatibility of additives in the plastic are improved effectively.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a low-cost black plastic. Background technique [0002] Halogen-free, low-smoke, low-toxicity, high-efficiency and environmentally friendly flame retardants have always been the pursuit of people. The application and development of halogenated flame retardants and flame retardant materials has also invested a lot of effort. [0003] Phosphorus-based flame retardants mainly include red phosphorus flame retardants, inorganic phosphorus-based APP, ammonium dihydrogen phosphate, diammonium hydrogen phosphate, phosphate esters, and organic phosphorus-based non-halogen phosphates. Inorganic hydrates mainly include magnesium hydroxide, aluminum hydroxide, modified materials such as hydrotalcite, etc. APP and hydrotalcite are representative products of this series of environmentally friendly products with good market prospects; APP is a long-chain inorganic polymer containing phosph...
