Description
Technical field
The present invention is strong and unyielding high-performance polypropylene matrix material of a kind of low smell and preparation method thereof.Belong to the polypropene composition of not managing with chemical after-treatment.
Background technology
Along with the fast development of household electrical appliances, automobile industry, environmental protection, lightweight and functionalization become the main trend of these industry developments at present, and plastics and matrix material thereof then become its important structure and finishing material.Vestolen PP 7052 (PP) is little with its density, cost performance is high, and characteristics such as excellent heat resisting, rigidity, erosion resistance and easy processing have obtained using widely in automobile, household electric appliances, become maximum, the with the fastest developing speed kind of consumption in automobile, the household electrical appliances plastics.
But shrinking percentage is big because general PP exists, the product size poor stability, is prone to buckling deformation; Poor, the easy brittle failure of low-temperature flexibility; Shortcomings such as heat-resisting, photooxidation aging property difference; Can't satisfy Hyundai Motor, the many parts of household electrical appliances, like bumper, test board, engine blower, inner tank of washing machine, refrigerator drawer, particular requirement; Therefore must carry out modification to general PP material, particularly aspect rigid-tough balance.
At present, improve PP flexible method and in the PP material, add toughner exactly.In the PP material, add toughner and can show normal temperature and the low-temperature flexibility that improves PP; But also can bring the decline of material stiffness and heat-drawn wire.Improving PP inflexible method, is exactly in the PP material, to fill high heat-resisting, high inflexible inorganic fillers.The adding of inorganic fillers can significantly improve rigidity, thermotolerance and the dimensional stability of material; But can reduce the toughness of material simultaneously.According to the particular requirement of automobile, household electrical appliances parts, optimize PP matrix, toughner, the triangular proportioning of weighting agent, the strong and unyielding equilibrated PP composite material that request for utilization is satisfied in exploitation is the problem that the technician is concerned about always.
In the prior art, aspect the strong and unyielding balance modification of PP composite material, be the most frequently used method through PP matrix, toughner, the triangular ratio optimization of weighting agent, wherein the selection of weighting agent is extremely important with dispersion.But because mostly weighting agent commonly used is spherical, spins the smaller crystal grain of major diameter such as awl property, improving the matrix material inflexible simultaneously, can reduce material toughness.Spun glass add rigidity and the toughness that affiliation increases matrix material significantly simultaneously, but because the spun glass production environment is polluted greatly, and the PP product of institute's modification has the fine problem of revealing, and limited its application in automobile, household electrical appliances plastic component.The nano-composite material blend improves the PP rigidity and toughness is a kind of novel method that development in recent years is got up.But because nano material crystal grain is little, surface curvature is big etc. characteristics; The atomicity that is present in the grain surface lack of alignment is greater than the shared percentage ratio of surface atom in the crystalline material; And also there are various defectives at same nanomorphic intragranular; Very easily reunite, do not have the purpose of nano redigity particle toughening, thereby its process for treating surface is the maximum technology barrier that limits its application.
In addition; For MODIFIED PP,, can have some obvious smells because the PP base resin possibly contain the compound that incomplete polymeric small molecules, initiator or catalyzer etc. residual in building-up process have pungent odour; Some powdery PP particularly, smell is more obvious; And in the modification course of processing, because autoxidation is decomposed under the hot conditions, the PP base resin also can produce some ketones, aldehydes etc. and have the small molecules of pungent odour, thereby makes the PP resin itself become the main source of MODIFIED PP smell.In addition, the mineral filler that adds in the modifying process, grafts, coupling agent, lubricant, stablizer etc. add auxiliary agent, and self or its remaining impurities also have irritating smell; And in the course of processing, might quicken the autoxidation of PP and decompose, will cause Vestolen PP 7052 " copper poisoning ", produce bigger smell like the copper metal ion that contains in the mineral filler.If smell is big, will pollute in the car or the space of comparatively sealing in the room, it is healthy to influence people, and this just can satisfy modern society to household product green, environmental protection, health and safe demand far from.
In order to limit the smell of inside gadget material; Guarantee HUMAN HEALTH, satisfy environmental requirement; The part auto maker has been worked out the smell volatility that several criteria is come the restricted internal gadget; Like the PV3900-2000 of Volkswagen, the BO131-03 of Ford Motor and the GMW3205 of General Motors etc., part household electrical appliances company also begins the smell volatility of plastic component material is proposed requirements at the higher level.Wherein, PV3900-2000 and BO131-03 adopt 1～6 grade of evaluation, and the high more smell of rank is big more, are not more than 3 grades and are specification product.This patent adopts BO131-03 that smell is graded.
Thereby, reply Hyundai Motor, household electrical appliances development and social enviroment protection demand, reduction smell, strong and unyielding balance are one of PP composite material important subject.
To strong and unyielding equilibrium problem; Zhang Kai, Zhang Xiangfu, Zhou Wen mention in patent CN 101712780A and are adding a small amount of Nano filling and guaranteeing on the basis of its good distribution; Add an amount of conventional talcum powder and toughening elastic body simultaneously; Can under relatively low density of material and cost condition, obtain the matrix material that over-all properties satisfies actual request for utilization.But, because the Nano filling addition is few, do not reach best strong and unyielding modified effect, and do not take into account the problem of material smell property simultaneously yet.
Aspect the modification of PP composite material reduction smell, can realize through selecting more purified resin and additive on the one hand, on the other hand can be through adding the smell suppressor factor, applied chemistry is reacted or the physical adsorption method is cut down the modifying material smell.Chemical reaction method is exactly that additive can react with the scent of small-molecule substance, produces not volatile or tasteless compound, thereby eliminates the method for smell.And physical adsorption then through some physical actions such as cavity absorption, adsorption by hydrogen bond, is adsorbed on the scent of small molecules on the sorbent material method that makes it be difficult for evaporating.Around above-mentioned factor, people do a lot.
Mention among the patent US5109056 that there is alkane compound in catalystsystem in the Vestolen PP 7052 polymerization process, the residual meeting of these materials causes opposite effects to the acrylic resin smell.The solution that proposes is to adopt in the high temperature extruding pelletization process to vacuumize, and the granulation high bake of producing, thereby eliminate residual small-molecule substance.
Propose among the patent US5041483 to solve the micromolecular compound that Vestolen PP 7052 receives the barbed sharp smell of thermo-cracking generation with rosin ester.
Propose to have the base material of odor control compositions among the patent US6376741, this base material comprises silica and zeolite, yet, not too effective at the odor control compositions that proof is conventional to comprehensive odour control.
Because the smell of MODIFIED PP is a polycomponent smell results of interaction, above-mentioned single method is head it off thoroughly, needs number of ways, several different methods to act on simultaneously, just is hopeful thoroughly to eliminate smell, satisfies automobile, household electrical appliances development need; And above-mentioned patent is not all considered the strong and unyielding balanced technical problem of MODIFIED PP when solving the smell problem.
