Abstract
Production of fire retardant for electronic products is carried out by taking wet phosphoric acid as initial raw material, reacting it with ammonia to prepare ammonium dibasic phosphate, grinding for ammonium dibasic phosphate and phosphorus pentoxide while mixing, putting them into kneading kettle, adding into ammonia to polymerize, raising temperature by three-stage process, polymerizing and modifying for polymonium phosphate surface by polyurethane coating material to obtain 500-mesh electronic fire retardant.
Description
Technical field
The present invention relates to phosphoric acid by wet process to make the manufacture method of electronic industry triammonium polyphosphate as starting raw material.
Background technology
Ammonium polyphosphate (APP) is that a kind of most important phosphorus that develops rapidly in recent years is inorganic combustion inhibitor, is one of main component of expansion type flame retardant (IFR), can be applicable to fields such as electronics, electrical equipment and automobile.China is from the twentieth century APP that begins one's study the eighties, and industrial scale is less at present, and the polymerization degree is low, and the quality instability can't satisfy the requirement that electronic industry is used.
Summary of the invention
The present invention with phosphoric acid by wet process as starting raw material, obtain Secondary ammonium phosphate with ammonia gas react and the Vanadium Pentoxide in FLAKES polymerization adds ammonia, utilize and mediate reactor and three sections intensification polymerization techniques, avoided dashing material, again modification is carried out on the ammonium polyphosphate surface, obtained electron triammonium polyphosphate fire retardant.
Technical scheme of the present invention is:
1. with phosphoric acid by wet process as starting raw material, get Secondary ammonium phosphate with ammonia gas react.
2. Secondary ammonium phosphate and Vanadium Pentoxide in FLAKES add ammonia and adopt three sections to heat up 170 ℃-180 ℃ through mediating the still polymerization, and 220 ℃-230 ℃, 290-300 ℃ of polymerization technique.
3. adopt the urethane coating material that modification is carried out on the ammonium polyphosphate surface.
With phosphoric acid by wet process as starting raw material, can with the integrated production of phosphorus ammonium, low to ingredient requirement, heat energy, waste residue, waste liquid, waste gas can be used for chemical fertilizers production workshop section in the production process, the process of producing product energy consumption is low, and the product cut size of production can reach 500 orders, and can carry out serialization production.
Specific embodiments
Earlier with phosphoric acid by wet process as starting raw material, produce Secondary ammonium phosphate with ammonia gas react, Secondary ammonium phosphate and Vanadium Pentoxide in FLAKES drop into after ground and mixed mediates still ammonification gas-phase (co-) polymerisation, adopt three sections to heat up 170 ℃-180 ℃, 220 ℃-230 ℃, 290-300 ℃ of polymerization technique polymerization obtains the ammonium polyphosphate particle, adopts the urethane coating material that modification is carried out on the ammonium polyphosphate surface again, obtains particle diameter and can reach 500 purpose electron triammonium polyphosphate fire retardants.
Figure of description is that production unit is mediated the polymeric kettle structure iron.
