Description
Technical field
The present invention relates generally to Material Field, particularly relates to a kind of igelite for arrangements for automotive doors plaque.
Background technology
Halogen, low cigarette, low toxicity, efficiently environment friendly flame retardant are the targets that people pursue always, some fire retardant supplies of the whole world in recent years and application business show very high enthusiasm to the non-halogen of fire retardant, have also dropped into very large strength to the application and development of halogen-free flame retardants and fire retardant material.
Phosphorus flame retardant mainly comprises the APP, primary ammonium phosphate, Secondary ammonium phosphate, phosphoric acid ester etc. of red phosphorus combustion inhibitor, inorganic phosphorus system, the non-halophosphate etc. of organophosphorus system.Inorganic hydrate mainly comprises magnesium hydroxide, aluminium hydroxide, material modified as hydrotalcite etc.APP, hydrotalcite are this serial environment-friendly type and the representative products of good market prospect; APP is that a kind of long-chain shape is phosphorous, the inorganic polymer of nitrogen.Because it has, chemical stability is good, water absorbability is little, dispersiveness is excellent, density is little, low toxin, is widely used in the fields such as flame retardant plastics, rubber, fiber; But there is the problem of a general character in domestic and international APP application process, the water tolerance being exactly APP is not good, and water absorbability is stronger.Therefore, hydrophobically modified process must be carried out when applying in some electron devices.At present, the method improving APP water resistance mainly contains: carry out surface treatment by coupling agent to APP, carry out micro encapsulation process to APP, utilize sol-gel processing technique to carry out the methods such as coating modification to APP.Wherein sol-gel processing technique generally adopts positive silicon ester to be hydrolyzed in-situ preparation orthosilicic acid, then polymerization generates the surface that polysiloxane is coated on APP, complete the coating modification to APP, due to the synergistic existence of SiO2 and APP, while improving APP water resistance, the flame retardant properties of APP can be improved.
Summary of the invention
The object of the invention provides a kind of igelite for arrangements for automotive doors plaque.
The present invention is achieved by the following technical solutions:

For a preparation method for the igelite of arrangements for automotive doors plaque, comprise the following steps:
(1) ethanol of above-mentioned 90-95% is joined in magnetic stirring apparatus, add ethyl cellulose under agitation condition, stirring and dissolving, obtain lysate;
(2) tetraethoxy, ten difluoro heptyl propyl trimethoxy silicanes are mixed to join in lysate, 20-30 minute is stirred when nitrogen protection, drip above-mentioned Glacial acetic acid, after dropwising at 50-60 DEG C stirring reaction 1-1.6 hour, obtain silicon sol;
(3) joined by ammonium polyphosphate in above-mentioned silicon sol, stirring reaction 2-3 hour, filter, wash, microwave drying, obtains silicon sol coated ammonium polyphosphate;
(4) PH is regulated to be 1-2 the aniline-water solution hydrochloric acid of above-mentioned 0.5mol/l, add above-mentioned coated ammonium polyphosphate, ultrasonic 30-35min in the ultrasonic dispersers that frequency is 36-40kHz, power 60-70W, send into magnetic stirring apparatus, stir 30-40 minute, sodium peroxide is dissolved in after in 6-10 times of distilled water and adds, stirring reaction 3-5 hour under normal temperature, product is used successively hydrochloric acid, dehydrated alcohol, deionization washes clean, filter cake is fully dry at 120-130 DEG C, obtains water resistant, flame-retardant additive;
(5) above-mentioned water resistant, flame-retardant additive are mixed with each raw material of residue, 600-1000 rev/min of dispersed with stirring 20-30 minute, feeding twin screw extruder melt extrudes, and the product extruded, through circulator bath cooling and pelletizing, obtains the described igelite for arrangements for automotive doors plaque.
Advantage of the present invention is:
First the present invention adopts tetraethoxy, ten difluoro heptyl propyl trimethoxy silicanes are precursor, first hydrolysis reaction is passed through, then further polymerization reaction take place, form the tight and shaggy coating film of one deck quality, also be coated on the surface of ammonium polyphosphate while being introduced by vinyl in coating film, effectively raise reactive behavior and the water resisting property of ammonium polyphosphate;
Then aniline is formed comparatively stable suspension in hydrochloric acid soln, after adding coated ammonium polyphosphate, a part is dispersed in the surface of coated ammonium polyphosphate film, part dispersion in the liquid phase, after adding oxygenant sodium peroxide, the polyreaction major part of aniline occurs in coated ammonium polyphosphate film surface, and the polyaniline of formation effectively delays the thermolysis effect of ammonium polyphosphate, improves flame retardant resistance, surface strength and additive dispersiveness in the plastic, consistency.
