Description
Technical field
The present invention relates to a kind of fiber glass reinforced ABS compositions, be specifically related to a kind of low abnormal smells from the patient fiber glass reinforced ABS compositions and
Its preparation method.
Background technology
Styrene-butadiene-acrylonitrile (ABS) resin with the rigidity of acrylonitrile and thermostability, polystyrene
The features such as the impact resistance of glossiness and processability and polybutadiene, are widely used in household electrical appliance, office equipment, instrument instrument
The fields such as table, transportation, construction material, household utensils and packaging material.Glass fiber reinforced ABS is used to improve further
The mechanical property of composite, and improve its heat resisting temperature.But owing to fiber glass reinforced ABS composite material abnormal smells from the patient is very big, limit
Make it in automobile, the application in the fields such as household electrical appliances.
The reason that fiber glass reinforced ABS composite material abnormal smells from the patient is big is many, and first, ABS resin in the fabrication process, is deposited
At more small molecular weight impurity, abnormal smells from the patient is more unpleasant, and total carbon emitting is the highest；And, at glass fiber reinforced ABS composite material
In preparation process, often adding and various add compatilizer, these compatilizers give off an unpleasant smell the most to some extent.
The basic skills reducing abnormal smells from the patient includes chemical reaction and physical absorption two kinds.Chemical reaction method refers to that some can be with
The additive of scent of small-molecule substance reaction, these additives and the reaction of little molecule, produce strand big, in general environment
The another kind of compound that can not evaporate, thus eliminate abnormal smells from the patient, such as zinc ricinate is to be dropped by chelating aldehyde ketone molecule
Low abnormal smells from the patient.And for physical absorption, theoretically, substantial amounts of cavity can be to any generation abnormal smells from the patient or other fugitive constituents
Little molecule adsorb, it is thus possible to produce odor problem various aspects the most effective.The most conventional physical absorption
Agent includes activated carbon, silica gel, attapulgite, clay mineral system, molecular sieve, zeolite, wollastonite, bentonite etc..
It is that resin raw material, stabilizer, mineral filler and processing cracking are produced that patent 200510026760.0 mentions abnormal smells from the patient
Raw, abnormal smells from the patient solution: nano zine oxide and nano titanium oxide.USP6297307 discloses what a kind of abnormal smells from the patient improved
ABS molded, by adding a kind of zinc oxide, magnesium oxide and the mixture of at least one epoxide, this method
Although abnormal smells from the patient can be improved, but the mechanical property of ABS alloy material is especially impacted and is had a great impact by these additives.
Said method to the odor problem of material by solution in various degree, but, said method is only for certain
The impact on abnormal smells from the patient of one component, thus add adsorbent to reduce abnormal smells from the patient, but actually material abnormal smells from the patient is various ingredients abnormal smells from the patient phase
The result of interaction.Therefore, develop and a kind of can solve various odor problem comprehensively and don't affect the ABS of the mechanical property of materials
Compositions is particularly important.
