Abstract

The invention discloses plastic containing colophony powder and polyvinyl chloride. The plastic comprises raw materials in parts by weight as follows: 100-106 parts of ammonium polyphosphate, 1.3-2 parts of glacial acetic acid, 1.3-2 parts of ethyl cellulose, 3-4 parts of tetraethoxysilane, 16-20 parts of dodecafluoroheptyl-propyl-trimethoxysilane, 30-34 parts of 90-95% ethyl alcohol, 160-200 parts of a 0.5 mol / l aniline aqueous solution, 5-10 parts of sodium peroxide, 460-500 parts of polyvinyl chloride, 2-3 parts of colophony powder, 6-10 parts of calcined gypsum powder, 2-3 parts of PTMG, 0.1-0.12 parts of cobalt iso-octoate, 13-18 parts of iso-octyl methacrylate and 1-2 parts of ammonium sulfate. According to the plastic, firstly, surface coating is performed on the ammonium polyphosphate with a sol-gel treatment technology, the surface strength and the water resistance are improved, then polyaniline coating is performed, the flame retardance and the thermal decomposition performance are improved, and the dispersity and the compatibility of an additive in the plastic are effectively improved.

Description

technical field [0001] The invention mainly relates to the field of materials, in particular to a rosin powder polyvinyl chloride 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 ...
