Abstract
The invention relates to an external lubricant for polyvinyl chloride, which is synthesized by pentaerythritol, adipic acid, trimethylolpropane and stearic acid as raw materials, and aims to solve the problems that the external lubricant has short plasticizing time and high plasticizing torque, and adopts long alkyl chain, branched chain structure and ester group with low polarity for end capping to achieve the plasticizing time of 180S and the plasticizing torque of 42 N.m, and the performance of the external lubricant is superior to that of the international advanced similar products at present.
Description
The present invention relates to the thermoplastic resin processing aid, be mainly used in the external lubricant of polyvinyl chloride (being called for short PVC) goods machine-shaping.
China uses stearic acid, paraffin wax and derivative to make external lubricant in the past always and uses, but stearic acid oilness deficiency and the paraffin wax oilness is excessive, generally be used for roughing PVC goods, but for technology and the product innovations such as slide, profiled material of precision work PVC, stearic acid, paraffin wax and other external lubricant all can not satisfy service requirements.Therefore it is moderate to synthesize a kind of oilness, can satisfy the external lubricant of service requirements.German Patent 3,630,783 (1988) have reported the external lubricant of thermoplastic resin processing, its structure is by 7 tetramethylolmethanes, 6 Succinic Acid and 14 stearic acid constitute, and there is hydroxyl at its main chain two ends, and its lubricity has reached service requirements substantially, be present reasonable external lubricant, but still have fusion time weak point, the high and baroque deficiency of plasticizing moment of torsion.
The objective of the invention is in order to overcome disadvantages of background technology, design that a kind of fusion time is long, the plasticizing moment of torsion is low and the external lubricating agent for polyvinyl-chloride use of designs simplification.
Design of the present invention: in order to realize above-mentioned purpose, at first understand, the consistency of external lubricant and PVC is very little, could in the course of processing, be easy to move and analyse the surface from PVC inside, at the interface, lubricant molecule orientations, polar group form a lubricant molecule layer towards the metallic surface by physical adsorption.Therefore the little external lubricant of just accelerating of consistency moves on to the surface from PVC inside, delays the time of PVC melting process, reaches the prolongation fusion time.Improve temperature of reaction and prolong the reaction times, impel the stearic acid end-blocking to generate the more weak ester group of polarity, replaced the hydroxyl at two ends and introduced the TriMethylolPropane(TMP) that can constitute branched structure; In order to lower the plasticizing moment of torsion, the hexanodioic acid replacement Succinic Acid with the alkane bond distance makes the chain length between the tetramethylolmethane increase like this, has lowered moment of torsion; For simplified construction, use 2 hexanodioic acids instead by 6 Succinic Acid, use two tetramethylolmethanes instead by 7 tetramethylolmethanes, use the synthetic external lubricant of 7 stearic acid instead by 14 stearic acid.
PVC of the present invention is as follows with the external lubricant structural formula:
R=C wherein

The present invention has compared following advantage with scape back of the body technology:
1, high temperature continuous lubrication performance is good: fusion time is long, reaches 180S, and the plasticizing moment of torsion only is 42 (N-m).
2, good mechanical property: tension intensity 589kg/cm
2, elongation 243%.
3, applied widely: as to be used for high transparent PVC sheet material, sheet material, torsion film, heat-shrinkable film.
4, raw material sources are abundant, cheap, the simple cost of technology is low.
Embodiment: one, the PVC synthetic route is as follows:

In the flask of the 1000ml that agitator, thermometer and distiller are housed, add TriMethylolPropane(TMP) 30.9g, hexanodioic acid 67.5g and catalyzer tin protochloride 0.9g, slowly heating up makes solid material all start stirring after the fusing, continues to be warmed up to 180-200 ℃ and carries out alkyd condensation reaction 2h.Stop heating and stirring, cool to 100-120 ℃ and in flask, add tetramethylolmethane 62.9g and stearic acid 438.5g again, stirring is warmed up under 190-210 ℃, carry out alcoholic acid esterification end capping 4h, at 170-180 ℃, further improve esterification 10-12h less than continuation under the vacuum condition of 17KPa again, reaction finishes and is cooled to 110-120 ℃ and filters, be cooled to the room temperature pulverizing again and make product 532.3g, yield 96%.Three, the structure qualification result is as follows:
