Description
Technical field
The invention relates to the material of the hard vinyl chloride molding that contains shock-resistant strengthening agent.
Background technology
Use maximum resins in the industry at present, it is known that oleophylic (ォ レ ピ Application) is arranged is resin and polyester, vinyl chloride resin and polystyrene, vinyl chloride resin particularly, because it is very good with the practicality of plasticizer, reinforcer one compounds, can use with multiple version, so be the resin that receives much concern.
Particularly vinyl chloride resin has good chemical resistance to mineral acid, alkali, oils etc., even in the very strong soil of seawater and corrodibility, can not get rusty etc. yet, owing to be material nontoxic, odorless, so it is health, in light weight, it is not only easy to install and transport, and has the easy advantage of the repairing of engaging, so be applied to thermoplasticity water pipe and window cabinet, plastic cloth and plastic containers etc. mostly.
Yet hard vinyl chloride resin has disadvantage, owing to just can produce thermolysis under common processing temperature, can not use so synthesize with regard to transfiguration takes place at the beginning, compare with ferrous material, impact strength is significantly inferior under the low temperature, is not suitable for being subjected to very much the environment of inside and outside power effect.
Therefore, sometimes vinyl chloride resin contains shock-resistant strengthening agent according to application target, mix with various types of additives, according to this technology, because final rerum natura has very big-difference, so the complex art of plastic raw materials and good hybrid technology must be arranged, just can produce good goods.
Particularly, in order to strengthen shock-resistance, and use chlorinated polyethylene resin is (Chlorinated Polyethylene, to call CPE system in the following text), polyisobutene acid methyl esters-(the Poly methyl methacrylate Butadien Styrene of butadiene-styrene system, to call MBS system in the following text), the shock-resistant strengthening agent of acrylic acid series etc. (lmpact Modifier), they are with regard to gelling characteristics, impact strength, weber (Weber) press workability, the pendulum shock strength, tensile strength, aspects such as weathering resistance, on working condition and goods rerum natura, respectively have relative merits.
Though the acrylic acid series shock-resistant strengthening agent is suitable for the plastic window frame material of the long-term weathering resistance of requirement, in general plastics tubing, plastic cloth and plastic containers, there is the difference on a lot of shaped structures, so be not suitable for purpose of the present invention.
In the rubber system that constitutes as shown in Figure 1, MBS is that shock-resistant strengthening agent is dispersed in wherein as constituent, has not only kept tensile strength, and aspect the impact, has also demonstrated very strong characteristic under the low temperature that influenced by very low Tg.
Can keep good tensile strength though MBS is a shock-resistant strengthening agent, and can give shock-resistance, the poor ability of opposing solar ray is so the problem of bringing is the extrusion torque that has increased in the extrusion machine.
Because hard vinyl chloride causes thermolysis under common processing temperature, so when making water pipe, added stablizer, but the tubing of picture drinking water using, in the time of must using non-lead to be non-toxic stabilizer, because extrusion torque is very big, is shock-resistant strengthening agent so can not use MBS.
Therefore, can add and can realize that very high effect, the CPE that weathering resistance is good are shock-resistant strengthening agent, it and vinyl chloride resin have good avidity, and have the effect of extrusion torque when reducing extruding, when molding is cut into unit length, can prevent to damage disconnected tangent plane again.
Because CPE is that shock-resistant strengthening agent has very strong resistance ability to solar ray, so with regard to the aspect that improves weathering resistance, have significant effect, as shown in Figure 2, because CPE is that shock-resistant strengthening agent and vinyl chloride resin have good avidity, so demonstrate the effect that reduces extrusion torque, when molding is cut into unit length, also demonstrate the effect that very high anti-breaking tangent plane damages.
Such CPE is a shock-resistant strengthening agent, in countries such as the U.S., with regard to cooperating in the pipe, generally adds 6～8 weight parts with regard to shock-resistant.
Yet, when making CPE be in a large number, its fluid has lost slick and sly property, and price is very high, not only uses to be subjected to very big restriction, and when single use CPE is shock-resistant strengthening agent, because impact strength reduces under the low temperature,, also be restricted aspect the bursting by freezing preventing in winter of cold during long-time the use, the a large amount of use again because the rapid reduction of tensile strength causes the problem that As time goes on deforms and damage.
Summary of the invention
Therefore, the present invention is for solving an above-mentioned class problem, and its objective is provides a kind of extrusion torque and low temperature impact strength, and all very good hard vinyl chloride resin of weathering resistance.
In order to achieve the above object, the invention provides a kind of hard vinyl chloride resin composition that contains shock-resistant strengthening agent, it contains shock-resistant strengthening agent, one package stabilizer, lubricant, processing aid, weighting agent and vinyl chloride resin, wherein, with respect to 100 weight part vinyl chloride resins, as shock-resistant strengthening agent, chlorinatedpolyethylene system and polyisobutene acid methyl esters-butadiene-styrene system are used in combination 8～12 weight parts, and chlorinatedpolyethylene system: the polyisobutene acid interpolation ratio that methyl esters-butadiene-styrene is with the ratio of weight part count 5: 5～7: 3; As one package stabilizer, using the lead system or the non-lead of 2.5～3.5 weight parts is stablizer; As lubricant, use the stearic acid and the polyethylene wax of 0.3～0.6 weight part.
For this reason, the present inventor has carried out a large amount of tests, and the result is clear and definite, and is shock-resistant with using the shock-resistant strengthening agent that must add in the hard vinyl chloride resin in processing, not only brought into play CPE system and MBS system strong point separately to greatest extent, and complementation weakness separately.
Fig. 3 is that manufacturing according to the present invention is the situation of shock-resistant strengthening agent than adding CPE system and MBS, by being the inhomogeneous shape that forms of the good avidity of shock-resistant strengthening agent and vinyl chloride resin by CPE and being the form of the inhomogeneous shape that forms between shock-resistant strengthening agent and vinyl chloride resin at MBS, owing to confuse the formation of existence, form dispersing morphology more stable when using CPE system or MBS to be shock-resistant strengthening agent separately, according to the structural property that has improved the ballistic shock-resistance in outside, thereby produce and both kept very high tensile strength, further improve the hard vinyl chloride resin of impact strength under the low temperature again.
Yet, the addition of shock-resistant strengthening agent in the said mixture, with respect to 100 weight part vinyl chloride resins, be that 8～12 weight parts are suitable, when being lower than the use of 8 weight parts, though the effect of the extrusion torque when reducing extruding is arranged, but do not improve the effect of impact strength, the problem of bringing is resist solar ray indifferent, weathering resistance does not improve, when surpassing the use of 12 weight parts, because the fluid in the forming mill is not slick and sly, cause that outward appearance is bad, generation contains the problem of the additive of shock-resistant strengthening agent to the transfer of vinyl chloride resin surface.
Particularly the manufacturing ratio of CPE system and MBS system is to regulate impact strength and weathering resistance isostatic important factor under crushing strength and the low temperature, so CPE system: the interpolation ratio that MBS is was in the ratio of weight part preferably 5: 5～7: 3.
At this moment add with the ratio that is higher than 7: 3, reduced the ratio of MBS system, though increased impact strength, but tensile strength can sharply descend, add with the ratio that is lower than 5: 5, improved the ratio of MBS system, though tensile strength has increased, but extrusion torque has also become greatly, thereby has reduced productivity.
In the molding of hard vinyl chloride resin, except adding shock-resistant strengthening agent, also can add one package stabilizer, lubricant, processing aid and weighting agent one class and various types of additive, in stablizer, can use the non-lead of plumbous system or brass one class is stablizer.
Lead is that stablizer is that stablizer is compared with non-lead, though can play the effect that reduces extrusion torque, but during the water pipe purposes that is used for directly contacting with tap water, must use the stablizer of non-plumbous system, when being applied to the undrinkable water goods of picture plastics outfall sewer, plate and container one class, can use lead is stablizer, when using non-lead to be stablizer, with CPE be: the interpolation of MBS system is counted 5: 5～7: 3 scope than calibration with the ratio of weight part, reduce the ratio of MBS system, use the exterior lubricant polyethylene wax, can make mixture fluid become slick and sly.
Lead is stablizer, tribasic lead sulfate (Tribasic Lead SulphateMonohydrous), three alkali formula lead stearates (Dibasic Lead Stearate), lead stearate etc. are arranged, owing to have excellent activity, so can be that shock-resistant strengthening agent uses jointly with MBS.
Stablizer preferably adds 2.5～3.5 weight parts, but less than 2.5 weight parts can produce the problem as resin carbonation one class when using, and when surpassing 3.5, the problem as frosting can take place.
Lubricant except the picture exterior lubricant of above-mentioned vinylchlorid wax one class, also can use the internal lubricant stearic acid, is ratio when being higher than MBS and being at CPE, and the exterior lubricant polyethylene wax is than internal lubricant stearic acid, and what are more, comparatively suitable.
Particularly, when the tap water water pipe that adds non-lead and be stablizer is used vinyl chloride resin, CPE system: the shock-resistant strengthening agent of MBS system with the ratio of weight part count 6: 4～7: 3 ratio adds, polyethylene wax and stearic acid preferably used 6: 4～7: 3 in the ratio of weight part.
On the other hand, when undrinkable water plastics outfall sewer, plate and the container that adds lead and be stablizer used hard vinyl chloride resin, CPS system: MBS be shock-resistant strengthening agent with the ratio of weight part count 5: 5～6: 4 ratio adds, polyethylene wax and stearic acid preferably use with the ratio of weight part count 5: 5～6: 4.
At this moment, the addition of lubricant is 0.3～0.6 weight part preferably, when less than 0.3 is used, can produce the uneven problem of shape, when surpassing 0.6 weight part, can produce the problem that gelation reduces.
Processing aid is the additive that must use in the hard vinyl chloride resin processing, and what see mostly is fusion promotor, for accelerating operation, pulverous raw material is heated into molten.
At this moment, the addition of processing aid is the 1-3 weight part preferably, when less than 1 weight part uses, do not improve the promoted effect of fusion, surpass when 3 weight parts are above to be used, just become the high price additive, adding man-hour must increase the power consumption of motor, and extrusion torque is risen.
Weighting agent can prevent the hard vinyl chloride resin static electrification, and accurate powder value and shape in order to keep pushing reduce cost, can use.
Weighting agent can use carbon ester calcium (CaCO
3), mainly be the surface of hard carbon, use lubricant to apply as stearic acid one class.
Such surface treatment weighting agent is easy to and other raw material blending, and physical propertiess such as tensile strength and spring rate can excessively not worsen yet.
During addition less than 3 weight parts of weighting agent, do not have filling effect, when surpassing 15 weight parts, impact strength significantly reduces.
Thus, the invention provides the superior tensile strength of both keeping hard vinyl chloride resin, good impact strength is arranged and extrusion torque is little in the extrusion molding operation hard vinyl chloride resin molding again, so be a good invention.
