Definitions
- This invention relates to a cleaning resin composition used for cleaning the inside of various molding machines. More particularly it relates to a cleaning resin composition obtained by blending a neutral salt of an alkylbenzenesulfonic acid, an inorganic filler and a water-repellent compound with a polyolefin resin.
- a cleaning agent composed mainly of a hard resin such as acrylic resins, a cleaning agent obtained by blending a nonionic surfactant with a thermoplastic resin, a cleaning agent obtained by blending a lubricant such as stearic acid with a thermoplastic resin, etc. have been developed.
- the cleaning agent obtained by blending stearic acid or the like with a thermoplastic resin is insufficient in the cleaning effect inside the molding machine, and in the case of the cleaning agent obtained by blending a nonionic surfactant with a thermoplastic resin, if the service temperature of the cleaning agent exceeds 250°C, vigorous evolution of decomposition gas occurs and also a characteristic odor occurs to have a bad influence upon the operational environment, and further the cleaning effect is insufficient with such a cleaning agent.
- the present inventors have made extensive research in order to obtain a cleaning resin composition by the use of which it is possible to effect color exchange inside various molding machines by exchanging the composition for the preceding colored resin or to clean the inside of the machines or to effect resin exchange for the preceding resin inside the machines, in a small quantity of the composition, in a simple operation and in a short time.
- a composition obtained by blending a neutral salt of an alkylbenzenesulfonic acid, an inorganic filler and a water-repellent compound with a polyolefin resin is a cleaning resin composition capable of solving the above-mentioned problems and have achieved the present invention based on this finding.
- the present invention resides in the following constitutions:
- polyethylene resins such as high density polyethylene, linear low density polyethylene, low density polyethylene, etc.
- polypropylene resins such as crystalline propylene homopolymer, crystalline propylene-ethylene copolymer, crystalline propylene-ethylene-butene-1 terpolymer or crystalline propylene-butene-1 copolymer each containing 70% by weight or more of propylene component, polybutene-1, non-crystalline ethylene-propylene copolymer (EPR), non-crystalline ethylene-propylene-diene terpolymer (EPDM) and mixtures of the foregoing.
- EPR non-crystalline ethylene-propylene copolymer
- EPDM non-crystalline ethylene-propylene-diene terpolymer
- preferred resins are high density polyethylene, linear low density polyethylene, crystalline propylene homopolymer, crystalline propylene-ethylene copolymer, crystalline propylene-ethylene-butene-1 terpolymer and mixtures of the foregoing.
- sodium salt of an alkylbenzenesulfonic acid used in the present invention, sodium salt of an alkyl necessarilybenzenesulfonic acid is preferably used.
- This sodium salt of an alkylbenzenesulfonic acid is one kind of anionic surfactants and its decomposition-initiation temperature is as high as 300°C.
- suitable alkyl groups for the neutral salt of an alkyl benzenesulfonic acid include linear or branched alkyl groups of C6 to C20.
- the surfactant displays a powerful effect upon cleaning of the inside molding machines even within a high temperature region; thus a superior cleaning effect is exhibited over from a low temperature region to a high temperature region.
- the quantity of the neutral salt of an alkylbenzenesulfonic acid blended is preferably 1 to 20% by weight, more preferably 5 to 15% by weight based on the weight of the composition. If the quantity thereof blended is less than 1% by weight, the cleaning effect is small when the inside of molding machines is cleaned with the resulting composition, while if it exceeds 20% by weight, notable foaming occurs when the resulting composition is granulated.
- Examples of the inorganic filler used in the present invention are those usually blended with polyolefin resins such as calcium carbonate, talc, calcium sulfate, magnesium silicate, silica, alumina, etc.
- the inorganic filler exerts a function of rubbing off dirties in the molding machine and the preceding resin adhered thereonto through a mechanical force.
- the quantity thereof blended is preferably 1 to 30% by weight, more preferably 5 to 20% by weight based on the weight of the composition. If the blended quantity is less than 1% by weight, the cleaning effect is insufficient, while if exceeds 30% by weight, the melt-fluidity of the resulting cleaning resin composition is reduced and too a large load is applied onto the molding machine at the time of cleaning.
- Examples of the water-repellent compound used in the present invention are synthetic waxes such as polyethylene wax, silicones, natural waxes, metal salts of higher fatty acids and mixtures of the foregoing.
- the quantity of the water-repellent compound blended is preferably 0.5 to 10% by weight, preferably 2 to 10% by weight.
- the water-repellent compound exerts a lubricating function. If the quantity of the water-repellent compound blended is less than 0.5% by weight, the lubricating effect is small, while if it exceeds 10% by weight, the lubricating properties are so strong that the mechanical force of the coexistant inorganic filler inside the molding machine is reduced.
- Phenolic antioxidants, thioic antioxidants, phosphorus antioxidants, etc. usually blend with polyolefin resins may be blended.
- composition of the present invention may be obtained by introducing a polyolefin and definite quantities of a neutral salt of an alkylbenzenesulfonic acid, an inorganic filler and a water-repellent compound and further at least one member of the above-mentioned antioxidants into an agitating and mixing device such as Henschel mixer (tradename), super mixer, etc. and agitating and mixing these materials for one to 5 minutes.
- an agitating and mixing device such as Henschel mixer (tradename), super mixer, etc.
- the resulting mixture may be subjected to melt-kneading and extruding at a melt-kneading temperature of 180° to 220°C, preferably 190° to 210°C by means of a single screw extruder or a twin-screw extruder into pellet form.
- Black resin pellets of any of ABS resin, PPS resin and modified PPO resin, difficult in color exchange, were injection-molded by means of a 35 tons injection molding machine in 50 shots, followed by cleaning the inside of the molding machine with cleaning resin compositions obtained in Examples 1-5 and Comparative examples 1-4, each in 100 g, by injection molding and repeating injection molding with a colorless polypropylene resin as a cleaning resin by the injection molding machine until the resulting molded products were not colored, to obtain the total quantity of the cleaning resin required therefor.
- Black resin pellets of either one of ABS resin or polyethylene reisn difficult in color exchange were extruded in 10 parisons (one parison: ca. 200g) by means of a blow molding machine having a die diameter of 21 mm and a core diameter of 19 mm, followed by cleaning the resulting blow molding machine with the cleaning resin compositions obtained in Examples 1-5 and Comparative example 1-4, each in 2,000 g, and then molding the parisons with a colorless polyethylene resin as a cleaning resin until the weld line of the resulting parisons where color exchange was most difficult was not colored to obtain the total quantity of the cleaning resin required therefor.
- parisons were molded with the ABS resin under the same conditions, followed by molding the parisons with the colorless polyethylene resin as a cleaning resin without using the cleaning resin compositions until the weld line of the resulting parisons was not colored, to obtain the total quantity of the cleaning resin required therefor.
- the cleaning resin composition of the present invention has a notably excellent cleaning effect at the time of color exchange of the preceding colored resin in various molding machines and also at the time of cleaning for exchange of the preceding resin.
- the cleaning resin composition of the present invention in a small quantity or by using the composition in a small quantity together with a cleaning resin, it is possible to far reduce the quantity of cleaning resins consumed and also notably shorten the cleaning period of time, as compared with the case where the inside of molding machines has so far been cleaned by exchange with cleaning resins each color exchange.
- the cleaning resin composition of the present invention displays a notably excellent effect at the time of color exchange and also at the time of resin exchange even in the case where engineering plastics such as modified PPO resin, polyphenylene sulfide resin, etc. as the preceding resin are molded at high temperatures.
