Abstract
The present invention provides a thermoplastic resin composition for cleaning molding machines, which has an excellent cleaning performance. The thermoplastic resin composition for cleaning molding machines contains 0.5 to 10 parts by mass of one or more surfactants which are selected from aliphatic surfactants and aromatic surfactants per 100 parts by mass of an AS resin which has an acrylonitrile content of not more than 28% by mass.
Description
Technical field
The present invention relates to be used to clean the resin composition for cleaning of molding machine inside such as forcing machine, injection moulding machine.
Background technology
As the clean-out system that the molding machine of thermoplastic resin is used, the known clean-out system that has composite substrate resin and tensio-active agent to form.What put down in writing in the embodiment of TOHKEMY 2000-119464 communique is, mixes Sodium dodecylbenzene sulfonate or alpha-olefin sodium sulfonate and the clean-out system that forms in the AS resin.
Summary of the invention
The problem of the present application is to provide a kind of cleaning force to be further enhanced and the thermoplastic resin composition of the clean-out system used as the molding machine of thermoplastic resin.
As the method for dealing with problems, the present application provides a kind of thermoplastic resin composition who is used to clean molding machine, in the said composition, with respect to AS resin 100 mass parts of acrylonitrile content below 28 quality %, contain tensio-active agent 0.5～10 mass parts, described tensio-active agent is selected from aliphatic category tensio-active agent and more than a kind or 2 kinds of fragrant same clan tensio-active agent.
In addition, the present invention also provides the molding machine cleaning use of above-mentioned composition.
The thermoplastic resin composition who is used to clean molding machine of the present invention, the combination by specific matrix resin and aliphatic category tensio-active agent or fragrant same clan tensio-active agent or their mixture has high cleaning performance.
The embodiment of invention
＜AS resin 〉
The AS resin that the present invention uses is that acrylonitrile content is the following AS resins of 28 quality %, and preferred acrylonitrile content is 20～28 quality %, and further preferred acrylonitrile content is 23～27 quality %.Aforesaid propylene nitrile content is the analytical value of measuring according to the assay method of putting down in writing among the embodiment.
＜tensio-active agent 〉
The tensio-active agent that the present invention uses, be the tensio-active agent more than a kind or 2 kinds that is selected from aliphatic category tensio-active agent and fragrant same clan tensio-active agent, preferably aliphatic category tensio-active agent more than a kind and the fragrant same clan surfactant mixtures more than a kind.
As the aliphatic category tensio-active agent, preference chain alkyl sulfonic acid sodium salt, alpha-olefin sulfonate sodium, as fragrant same clan tensio-active agent, preferred alkyl Phenylsulfonic acid sodium salt.The carbon atom number average preferred 8～20 of alkane, alpha-olefin and alkylbenzene in alkansulfonic acid sodium salt, alpha-olefin sulfonate sodium, the alkyl benzene sulphonate (ABS) sodium salt.Salifiable metal species is for being selected from more than a kind of basic metal or alkaline-earth metal.
For the content of tensio-active agent in the present composition or surfactant mixture, with respect to AS resin 100 mass parts, preferred 0.5～10 mass parts, further preferred 0.5～6 mass parts, more preferably 3～6 mass parts, further preferred 1～3 mass parts.
For the blending ratio (mass ratio) during for use aliphatic category tensio-active agent and fragrant same clan surfactant mixtures, the scope of above-mentioned blending ratio (aliphatic category tensio-active agent/fragrant same clan tensio-active agent) preferred 1/10～10/1, further preferred 1/6～6/1 scope, further preferred 1/3～3/1 scope.
＜other compositions 〉
Composition of the present invention, known mineral fillers such as all right combined fiberglass, asbestos.As the content of mineral filler, with respect to AS resin 100 mass parts, preferred 0.5～150 mass parts, further preferred 20～140 mass parts, further preferred 40～120 mass parts.
In the scope that can solve problem of the present invention, can contain known various additive in the composition of the present invention.As known additive, in can using the 12nd, 13 sections in for example above-mentioned TOHKEMY 2000-119464 communique, the alkylidene diol fatty acid ester of record, can also use the phosphate compounds of putting down in writing among polyvalent alcohol or metallic soap, the TOHKEMY 2002-1734.
Composition of the present invention can make by following method, described method is: after using mixing machines such as Henschel mixer, rotary drum mixer, kneader that each composition is pre-mixed, use forcing machine to carry out melting mixing, re-use the method that warming mill, Banbury mixer carry out melting mixing.
Embodiment
Embodiment 1～7, comparative example 1～6
After using rotary drum mixer that each composition of forming shown in the table 1 is mixed, melting mixing in forcing machine obtains granular resin composition for cleaning.Use above-mentioned composition, implement washing test according to following method.The result is as shown in table 1.
At injection moulding machine (" the injection moulding machine 265/100MSII of Mitsubishi " that Mitsubishi Heavy Industries Ltd already make; 250 ℃ of barrel temperatures) in, inject 1kg as the ABS resin of in advance using resin (the Cest Bien V550SF that the Daicel polymkeric substance is made) black product (dry color; Carbon black concentration 2%).Then, inject each resin composition for cleaning that table 1 is formed, estimate, continue to inject AS resin (the Cest Bien N 050SF that the Daicel polymkeric substance is made) according to the consumption of the composition when black disappears, and carry out injection moulding, whether confirm has black residual in the moulding product.
(AN in the AS resin contains proportional measuring method)
Use nitrogen analysis device (living fractional analysis center (strain) makes) to measure by the nitrogen amount.Described nitrogen analysis device is made of SUMIGRAPH NC-90A (living fractional analysis center (strain) makes), GC-8A (Shimadzu Scisakusho Ltd's manufacturing), C-R6A (Shimadzu Scisakusho Ltd's manufacturing).
AS-1:AS resin (AN measures 24.3 quality %)
AS-2:AS resin (AN measures 27.0 quality %)
AS-3:AS resin (Cest Bien N 080 AN that Daicel polymkeric substance Co., Ltd. makes measures 29.5 quality %)
Tensio-active agent 1: Sodium dodecylbenzene sulfonate
Tensio-active agent 2: alpha-olefin sodium sulfonate
GF: glass fibre (" ECS03T351/P " that NEG (strain) is made " (Fibre diameter 13 μ m; staple length 3.2mm; use aminosilane one type of silane coupling agent to carry out surface treatment, and use the crylic acid resin collecting agent to implement that boundling is handled and the glass fibre that obtains).
From the contrast of embodiment and comparative example as can be known, by use the AN amount be resin below the 28 quality % as the AS resin, can improve cleaning performance.In addition, as tensio-active agent, use the example (embodiment 1～5) of aliphatic category and fragrant same clan mixture, compare with the example (embodiment 6,7) of independent use tensio-active agent, cleaning performance also is improved.
