Description
Technical field
The present invention relates to a kind of fiber glass reinforced ABS composition, be specifically related to a kind of low smell fiber glass reinforced ABS composition and method of making the same.
Background technology
Vinylbenzene-divinyl-vinyl cyanide (ABS) resin is with rigidity and the thermotolerance of vinyl cyanide, the features such as shock resistance of the glossiness of polystyrene and processibility and polyhutadiene, are widely used in the fields such as household electrical appliance, office equipment, instrument, communications and transportation, material of construction, household utensils and wrapping material.Use glass fiber reinforced ABS can further improve the mechanical property of matrix material, and improve its heat resisting temperature.But because fiber glass reinforced ABS composite material smell is very large, limited it at automobile, the application in the fields such as household electrical appliances.
The reason that fiber glass reinforced ABS composite material smell is large is many-sided, and first, ABS resin, in manufacturing processed, exists more small molecular weight impurity, and smell is more unpleasant, and total carbon emitting is also higher; And, in the preparation process of glass fiber reinforced ABS composite material, tending to add the various compatilizers that add, these compatilizers tend to give off an unpleasant smell to some extent.
The basic skills that reduces smell comprises two kinds of chemical reaction and physical adsorptions.Chemical reaction method refers to the additive that some can react with scent of small-molecule substance, these additives and small molecules reaction, produce the another kind of compound that molecular chain is large, can not evaporate in general environment, thereby elimination smell, for example zinc ricinate reduces smell by chelating aldehyde ketone molecule.And for physical adsorption, theoretically, a large amount of cavities can be adsorbed the small molecules of any generation smell or other fugitive constituents, therefore may all produce effect to producing all respects of smell problem.Conventional physical absorbent comprises gac, silica gel, Attapulgite, clay mineral system, molecular sieve, zeolite, wollastonite, wilkinite etc. at present.
It is that resinogen material, stablizer, mineral filler and processing cracking produce that patent 200510026760.0 is mentioned smell, smell solution: nano zine oxide and nano titanium oxide.The improved ABS alloy of a kind of smell molding is disclosed in USP6297307, by adding the mixture of a kind of zinc oxide, magnesium oxide and at least one epoxy compounds, although this method can be improved smell, these additives especially impact and have a great impact the mechanical property of ABS alloy material.
Aforesaid method to the smell problem of material by solution in various degree, yet aforesaid method is only the impact on smell for a certain component, reduce smell, but in fact material smell is the interactional result of various ingredients smell thereby add sorbent material.Therefore, develop a kind of ABS composition that can solve various smell problems comprehensively and don't affect the mechanical property of materials and seem particularly important.
