Description
Technical field
The invention belongs to technical field of macromolecules, relate to blend of a kind of liquid crystalline polymers and preparation method thereof.
Background technology
TLCP (TLCP) has become the technological highland that industrial development is competitively striven for.Liquid crystal high polymer material has excellent mechanical property, has obtained using widely at many high-technology fields.Liquid crystalline polymers has HS, and the high-modulus mechanical property also has good thermostability, thermotolerance and chemical proofing, and wear-resisting, anti-attrition property is all excellent.Weathering resistance, the radiation resistance of TLCP are good, have excellent flame, can knock down the flame and no longer proceed burning.Its burning grade reaches UL94V-0 level level.TLCP is one of best special plastic of fire savety.
But because TLCP has limited its application and development in industry in fancy price on the market, the means of utilizing TLCP of seeking a kind of low price have become the direction of many scientific research personnel and company's effort.
TLCP can also process alloy with plastic blends such as polysulfones, PBT, polymeric amide, and physical strength is high after the product moulding, in order to plastics such as replacement spun glass enhanced polysulfones, both can improve mechanical strength properties, can improve working strength and chemicalstability etc. again.
Nearly decades, nylon has had significant progress in industry and in life.But recent years is because being widely used of electric industrial expansion, especially SMT (surface mounted technology), and what be is increasingly high to each item performance demands such as material are high temperature resistant in industry.And high temperature resistant nylon relies on its HMP, and the favorable mechanical performance opens a slice world gradually in industry now.
Used high temperature resistant nylon is the PA46 of DSM the most widely at present, but because PA46 still is an aliphatics nylon, at high temperature resistant and still too late aromatic series of mechanical properties or semi-aromatic nylon.Therefore, the semi-aromatic nylon PA9T that is developed on a large scale very much now, PA10T, PA6T etc.Shortcomings such as but the flowability of high temperature resistant nylon is poor, processing characteristics is bad, mechanical property can not satisfy industrial requirements embody gradually; So mechanical property, processing characteristics in order to seek a kind of better raising high temperature resistant nylon; Increase its flowability, the polymkeric substance of special a kind of high temperature resistant nylon of invention and TLCP blend.
Because high temperature resistant nylon belongs to thermoplastic polymer, is the blend matrix with the high temperature resistant nylon, TLCP is as toughener; Make TLCP in-place mo(u)lding in the blend course of processing, become microfibrillar structure, support in-situ composite; Improved the mechanical property of nylon greatly; Simultaneously because the TLCP melt has lower viscosity, can improve the processing flowability of nylon with the blend of high temperature resistant nylon, utilize its HS and high-modulus characteristic; Join in the high temperature resistant nylon processing, reduce wearing and tearing and the energy consumption of materials processed equipment.
Summary of the invention
The objective of the invention is to be directed against the processing difficulties that present high temperature resistant nylon exists in Industrial processes; Mobile poor; Mechanical property is low; Material is hard and crisp, and shortcomings such as liquid crystalline polymers selling at exorbitant prices provide that a kind of easy processing, mechanical property are good, HS, high inflexible HPN/TLCP matrix material and preparation method thereof.
To achieve these goals, the technical scheme of the present invention's employing is following:
A kind of blend of high temperature resistant nylon/liquid crystalline polymers comprises following component and parts by weight thereof:
High temperature resistant nylon (HPN) 70-90 part
TLCP (TLCP) 5-10 part
Compatilizer 5-10 part
Oxidation inhibitor 0.2-1.0 part
Lubricant 0.2-0.8 part
Described high temperature resistant nylon is a semiaromatic polyamide composition, and fusing point is 280 ℃～310 ℃, and density is 1.10～1.25g/cm
3
Described high temperature resistant nylon is selected from poly terephthalic acid hexanediamine (PA6T), poly terephthalic acid nonamethylene diamine (PA9T), poly terephthalic acid decamethylene diamine (PA10T);
Described liquid crystalline polymers is commercially available thermic property polyester liquid crystalline polymers, and heat-drawn wire is 230 ℃, and processing temperature is 280-330 ℃;
Described compatilizer is polycthylene grafted maleic anhydride (PE-g-MAH) or maleic anhydride graft SEBS;
Described oxidation inhibitor is neutralized verdigris, cupric iodide, potassiumiodide, Hinered phenols (oxidation inhibitor 1098 and auxiliary antioxidant 168); Preferred Hinered phenols antioxidant 1098 and the auxiliary antioxygen of using is with regard to 168 composite uses;
Described lubricant is selected from barium stearate, stearylamide, polyethylene wax, calcium stearate or Zinic stearas, preferred calcium stearate, Zinic stearas.
A kind of method for preparing above-mentioned high temperature resistant nylon/TLCP blend may further comprise the steps:
(1) earlier that high temperature resistant nylon, TLCP is dry respectively, the drying temperature of high temperature resistant nylon is that 80-100 ℃, the drying temperature of TLCP are 120-140 ℃;
(2) with compatilizer, oxidation inhibitor, lubricant dry 4h under 90-120 ℃ of condition respectively;
(3) dried HPN, TLCP, oxidation inhibitor, lubricant, compatilizer are put in the impeller, carried out high-speed stirring, mix;
(4) mixture that obtains in (3) is joined in the twin screw extruder, melt extrude granulation, extrusion temperature is 290 ℃-320 ℃.
Described forcing machine is a twin screw extruder; Extrusion temperature is: a district: 270-280 ℃, two districts: 280-295 ℃, three districts: 295-305 ℃, four districts: 305-320 ℃, five districts: 310-320 ℃, six districts: 295-310 ℃, seven districts: 280-295 ℃, head 170-190 ℃; The twin screw rotating speed is 100-200r/min, residence time 1-4min.
The step of this method (1) because the water-absorbent of HPN is higher, is therefore opened oven dry respectively with itself and TLCP branch, and HPN is for use at 75-110 ℃ of following vacuum-drying 24h, and preferred 80-100 ℃, oven dry 4-6h is for use down at 110-150 ℃ for TLCP, preferably 120-140 ℃.
The invention has the advantages that:
The present invention prepared HPN/LCP intermingling material, it is poor not only to have overcome the flowability that the HPN material had, and shortcoming such as processing characteristics is low has enlarged the rate of utilization of HPN in industry; Also avoid simultaneously the shortcoming of the anisotropic of TLCP material in the processing use, can reduce the too high drawback of use cost that when using the TLCP material separately, is occurred in addition, expanded the use range of TLCP in industry greatly.
On the other hand, because the processing temperature of HPN is all in 280-320 ℃ of scope, the processing temperature of this temperature and TLCP is very close, has made things convenient for the later processing treatment in industry of material; HPN connects in the section with the TLCP molecule and contains identical-C=O group; Increased the consistency between two; As long as add the compatilizer of very small amount; Just can be that both reach the compatible effect of extraordinary blend, this blend has very high practical value in industry, can be used for automotive industry, electric industry etc.
