Description
Technical field
The invention belongs to enhancing technical field of polymer materials, be specifically related to a kind of long glass fiber-reinforced polypropylene goods and preparation method thereof.
Background technology
Long glass fiber-reinforced polypropylene (Long Glass Fiber Reinforced Polypropylene. is called for short LGFPP) has the features such as high rigidity, high impact strength, creep-resistant property, low warpage, anti-dynamic fatigue and good stability of the dimension, is widely used in the field such as automobile, building materials in recent years.
In order to make glass fibre play the effect improving intensity well in polypropylene, glass fibre length must be made to be greater than its critical length.Prior art data shows, when in fiberglass reinforced plastics, staple length is less than this critical length, fiber is subject to certain load and will be pulled out, and can not play fibre-reinforced effect.Critical length is relevant with concrete plastics variety, the critical length of fiber glass reinforced polypropylene is 3.1mm, and the Length of Glass Fiber of regular staple Reinforced Polypropylene generally only has 0.2 ~ 0.6mm, thus short fiber reinforced polypropylene material cannot meet high strength service requirements.Therefore, developing long glass fiber-reinforced polypropylene is exactly to prepare Reinforced Polypropylene material and the goods that Length of Glass Fiber is greater than critical length.
Chinese patent ZL200610033859.8 discloses a kind of long glass fiber reinforced polypropylene material and preparation method thereof, during this invention adopts, melt flow rate polypropylene resin prepares superelevation melting means unsaturated carboxylic acid or its anhydride modified polypropylene composite in an extruder, becomes length to be the long glass fiber reinforced polypropylene material particle of 3 ~ 30mm directly enter the continuous glass fibre of dipping head dipping traction from forcing machine after through tank cooling and dicing.This invention adopts the middle melt flow rate polypropylene of 10-20g/10min, the inapplicable tubing article required with production high strength, and is prepared into 3 ~ 30mm particulate material, makes glass be forced to cut off, is difficult to the requirement reaching critical length 3.1mm.
Chinese patent ZL200610045857.0 relates to continuous fiber reinforced composite materials, with resin and treating compound process glass fibre for main raw material, with antioxidant, UV light absorber, photostabilizer mixture is main auxiliary agent, adopt glass fibre dispersion system, the continuous glass fibre reinforced composite of the design production of fiberglass surfacing treatment technology and special cross slot die, through matrix material tension system, the continuous fiber reinforced composite materials that pellet length can be selected on demand is formed after cooling granulation system, in pellet, staple length can reach 15mm, fibre content can reach 40-60%.This patent is need granulation equally, although Length of Glass Fiber exceedes critical length, also need to enter forcing machine again when making goods after granulation again, pellet can be sheared further thus reduce material property.

Described components b) graft polypropylene preparation in polypropylene: under temperature 230 DEG C, load 2.16kg condition, melt flow rate (MFR) is 0.05 ~ 10g/10min; The crushing-resistant copolymerization PP-B of preferred melt flow rate (MFR) 0.1 ~ 9g/10min or the random copolymerization PP-R of melt flow rate (MFR) 0.1 ~ 9g/10min.
Described amount of component b) long glass fibres be via coupling agent treatment after continuous long glass fiber.Coupling agent is selected from titanate coupling agent, aluminate coupling agent or silane coupling agent; preferred titanate coupling agent, wherein more preferably isopropyl tri (dioctylpyrophosphato)titanate, two (dioctylphosphato) metatitanic acid second diester and diisostearoyl ethylene titanate or γ-aminopropyl triethoxysilane.For making the better dispersing glass fibers of coupling agent, first using diluents dilutes coupling agent, and thinner is selected from white oil or whiteruss, and the weight ratio of coupling agent and thinner is 1:1 ~ 20, preferred 1:1 ~ 10.
The preparation method of described long glass fiber-reinforced polypropylene sheet material is:
By component a) Co-polypropylene add in forcing machine A, by components b) graft polypropylene adds in the forcing machine B placed with described forcing machine A right-angled intersection, now by amount of component b) long glass fibres adds in forcing machine B, forcing machine A and forcing machine B is expressed in a slot die jointly, through cooling, traction system, prepare long glass fiber-reinforced polypropylene sheet material.

For making long glass fibres not by excessive shear, control extruded velocity not too high.The temperature range of described forcing machine A, forcing machine B and forcing machine C is 170 ~ 250 DEG C.
Via the interface binding force that coupling agent treatment glass fibre is to improve glass and PP resin.Because coupling agent and PP and glass have affinity to a certain degree, namely one end (hydrophilic group) of its molecule is hydrolysable group, silicone hydroxyl after hydrolysis can with the silicone hydroxyl generation condensation reaction on glass surface, chemical bond is formed with glass surface, realize good interface cohesion: and the other end (oleophilic group) and PP form physical bond, thus the bonding force at the two interface is strengthened, thus the mechanical property of fiberglass reinforced PP can be improved.
The over-all properties that increase-volume fiberglass reinforced PP can significantly improve material is carried out with the grafts of the unsaturated carboxylic acids such as maleic anhydride (MAH) and PP.When grafts consumption is in certain limit, the mechanical property of fiberglass reinforced PP increases with consumption and strengthens: after consumption exceedes certain limit, gain in strength slows down.This is that the grafted monomer of its polarity and fiberglass surfacing interact due to after add a small amount of grafts in fiberglass reinforced PP, forms ionic linkage, adds the bonding interface between PP and glass fibre.Along with the increase of grafts consumption, the surface of its coated glass fibre increases gradually, the interface avidity of resin and glass is increased, thus make its tensile strength and shock strength improve very fast: but when grafts reaches a certain amount of, the interface of PP resin and glass fibre oneself be covered with polypropylene grafted unsaturated acid anhydride, increase its consumption again, unnecessary grafts is inoperative.And due to large usage quantity, the impact of mechanical and physical performance on fiberglass reinforced PP material of grafts itself account for leading role, intensity substantially no longer increases.
