Description
Technical field
The present invention relates to technical field of polymer materials, more particularly, to high-intensity high-tenacity continuous glass-fiber RPP
Sheet material and preparation method thereof.
Background technology
It is that one kind is different from short glass fiber RPP material that continuous glass-fiber increases crystalline p p sheet, due to glass fibre length
Difference, in the case of fiber content identical, continuous glass-fiber RPP compared with short glass fiber polypropylene, continuous glass-fiber increase
Glass in strong crystalline p p sheet is in continuously unidirectional arrangement, with intensity higher, modulus, toughness and more preferable dimensionally stable
Property.
Influenceing the principal element of continuous glass-fiber RPP sheet material physical property mainly has two aspects：1, polypropylene with
Polyacrylic interface fine structure has a significant impact to its performance；2, the mobility of polymer melt influences acrylic resin and gathers
The impregnation state of propylene, so as to influence the physical property of final continuous glass-fiber RPP sheet material.
In continuous glass-fiber RPP sheet material preparation process, polypropylene and glass need the combination could fully to send out
The high-strength characteristic of glass is waved, and polypropylene and glass are due to the connection without chemical bond, it usually needs additionally add maleic acid
Acid anhydride graft polypropylene is used as compatilizer of the glass in polypropylene, and the addition of graft can cause process small molecular
Distributing for acid anhydrides, is polluted to environment, it is therefore desirable to which compatilizer system is changed.Polyacrylic viscosity is lower, its stream
Dynamic property is better, and resin is more abundant to polyacrylic dipping.The preparation of continuous glass-fiber RPP is typically referred to using melting high
, used as material resin, for general linear polypropylene, melt index is higher, and strand is shorter, thus polypropylene for number polypropylene
The shock resistance of resin declines more obvious.Due to there is amido link on the strand of NYLON610, its surface parent to glass
It is moderate with power so that nylon molecules chain is preferable to the dipping effect of glass, and the carbochain in the middle of each amido link is more long, with polypropylene
Mutually there is stronger interface affinity, thus can be using NYLON610 as polypropylene and the interphase of glass, so as to reach polypropylene
It is indirectly connected to glass, so as to play humidification of the glass in polypropylene to greatest extent.
The content of the invention
The purpose of the present invention be overcome eutectic polypropylene mobility in continuous glass-fiber RPP production process it is low,
Melting means polypropene impact-resistant intensity difference high, and the odor dispersion problem that compatilizer maleic anhydride inoculated polypropylene is brought, carry
For a kind of method of modifying of high-intensity high-tenacity continuous glass-fiber RPP sheet material, the present invention can prepare mobility, compatible
Property, rigidity and all excellent modified polypropene sheet material of toughness.
The technical problems to be solved by the invention are：For above-mentioned technical disadvantages, a kind of continuous glass-fiber enhancing poly- third is proposed
Alkene sheet material and preparation method thereof, can strengthen polypropylene mobility and its dipping effect with glass fibre, increase the strong of material
Degree and toughness.
The purpose of the present invention is to be achieved through the following technical solutions：
A kind of high-intensity high-tenacity continuous glass-fiber RPP sheet material, including the following raw material counted by weight：
Wherein, described polypropylene is melting means polypropylene high, and melt index is 10~50g/10min, and test condition is 230
℃×2.16kg。
Described NYLON610 molecular weight is 5000~15000g/mol.
The continuous glass-fiber is the special alkali-free glass fiber of polypropylene, and its surface is processed through silane coupler, the glass fibers long
Tie up a diameter of 5-20 μm.
The lubricant short chain polypropylene and polyethylene and ethylene copolymers.
The antioxidant be selected from Hinered phenols, hindered amines, phosphite ester or thioether kind antioxidant in one or more,
Including antioxidant 1010, irgasfos 168, antioxidant 3114, one or more in antioxidant 619 or antioxidant DSTP.
Polypropylene is two kinds of different phase materials from glass fibre, and both affinity are poor, and polypropylene soaks to glass fibre
After stain, also there is two-phase laminated flow situation under microstate, thus there is gap between glass and polypropylene, when environment temperature hair
During raw change, glass easily comes off from polypropylene matrix, so as to cause material failure.In the present invention, the addition of NYLON610
The effect of a linking glass and polypropylene matrix can be functioned well as, the amido link of NYLON610 is connected with glass surface, separately
One end fusion is in the mixed matrix of polypropylene and NYLON610.As can be seen here, the present invention dexterously uses polypropylene and nylon
610 is main resin matrix, so as to reach the indirect combination of polypropylene and glass in the case of without Graft Polypropylene,
And give full play to the effect of fiberglass reinforced.
The lubricant short chain propylene and ethylene copolymer, and the lubricant such as stearic acid, butyl stearate for generally using
The problems such as impact property of material being damaged, and there may be precipitation frosting, and short chain propylene is solved just with ethylene copolymer
Problem above.
The preparation method of above-mentioned high-intensity high-tenacity continuous glass-fiber RPP sheet material, comprises the following steps：
(1) polypropylene, NYLON610, antioxidant, lubricant are added in high-speed mixer and are fully mixed；
(2) mixture that step (1) is obtained is added to melting mixing in double screw extruder；
(3) blend melt is expressed into special dipping die cavity, continuous glass fibre is then drawn through dipping former
Head, cooling is in blocks, obtains continuous glass-fiber RPP sheet material.Extrusion temperature is respectively：100 DEG C, 180 DEG C, 200 DEG C, 220
DEG C, 240 DEG C, 260 DEG C, 280 DEG C, 300 DEG C.Engine speed is 350rpm.
It is an advantage of the invention that：
1, polyacrylic viscosity can be selected in a wide range, and low viscosity polypropylene is selected without limitation；
2, it is not necessary to add small molecule class flow ability modifying agent, effectively prevent material from separating out frosting problem.
3, it is not necessary to add maleic anhydride inoculated polypropylene, effectively prevent distributing for the small molecule smell such as acid anhydrides.
