Description
Technical field
The present invention relates to a kind of polypropene composition, particularly a kind of low polypropene composition that distributes.The present invention gives a kind of low preparation method who distributes polypropene composition.
Background technology
Automobile bodies is owing to often be in closure state, thereby the inner air quality often receives the influence of organic cpds (TVOC) such as free formaldehydes that interior products produces such as skin chair cover or cloth chair cover, alkane, benzene, toluene, thereby to human body generation detrimentally affect.For reducing the TVOC content in the material; Need control from aspects such as starting material source, complete processing, additives; Or add the material that can react with these small molecules volatile matter; It is bigger to generate molecular weight, not volatile can the stable existence material in and the compound that is difficult for evaporating, thereby reach the purpose that reduces TVOC.Patented claim WO2007052074-A2 discloses a kind of palladium doped molecular sieve and has adsorbed VOC gas, and this molecular sieve is adsorb volatile gas long-term effectively, in wet environment, is a kind of cost-effective VOC remover particularly; Chinese patent CN1727390A discloses PP composite material of a kind of low smell and preparation method thereof; Its method is in system, to add alkali metal aluminosilicate powder smell remover (sodium type molecular sieve); Bad smell in the absorption system is prepared the PP composite material that hangs down smell.
Yet the method that reduces TVOC through chemical reaction often only is directed against a factor that produces TVOC, can not solve the TVOC problem that various factors produces simultaneously; Physical adsorption does not possess particular selecting property, can the small molecules of all generations be adsorbed, and has a shortcoming but the adding molecular sieve prepares low TVOC polypropylene material: can not add oily substance in the system.In actual production process; Generally to obtain the uniform compsn of performance; Need to add a certain amount of white oil or MO and stick to resin material grain surface, and then with vacuum this part is added oil and remove, thereby come preparing product to have congenital defect with molecular sieve by filler.
No matter chemisorption or physical adsorption all is the removal of low molecular weight volatile material that system or system are produced in the course of processing, do not block the source that produces these VOC.Thereby, need to add a kind of material and cut off the VOC that produces in the course of processing.EP2141196A1 discloses a kind of preparation method of low VOC polypropene composition; It utilizes in the epoxy resin ester group and the talcum powder surface in the epoxide group and polyester to carry out bonding, thereby hinders the polypropylene modified material of the VOC that the DeR that takes place between talcum powder and the oxidation inhibitor obtains; EP2141193A1 discloses the employing carboxylic-acid substance and the talcum powder surface forms skim through covalent linkage or ionic linkage, and this skim has reduced the catalytic activity on talcum powder surface, thereby hinders the DeR between talcum powder and the oxidation inhibitor; Chinese patent 200910212885.0 discloses modified polypropylene composite material of a kind of scrape resistant and preparation method thereof; Its method is for to add toughner, mineral filler, anti-wear agent etc. in polypropylene material, and reaches the purpose of modification through cooperatively interacting of various ingredients.The addition of these additives is often less, and is generally solid, can not on filling surface, form the layer of even film.
