Abstract
The invention discloses a screw detergent for injection molding industry. The screw detergent comprises the following components in percentage by weight: 1-2.5% of Tween-60, 2.0-4.0% of potassium hydroxide, 0.5-1.0% of sodium phosphate, 0.1-0.5% of aluminum sulfate, 0.1-0.3% of sodium dodecyl benzene sulfonate and the balance of water. The invention further provides a preparation method of the screw detergent, comprising the steps of slowly adding potassium hydroxide into water, and quickly stirring till complete dissolution; and then adding sodium phosphate, aluminum sulfate, Tween-60 and sodium dodecyl benzene sulfonate, and stirring till complete dissolution, thus obtaining a finished product. The screw detergent has a good cleaning effect; when a small amount of the screw detergent is mixed with raw white plastic or raw plastic which is required by subsequent injection molding and the mixture is fed into a molding machine, the previous injection molding color can be cleaned, so as not to influence the subsequent injection molding operation; and the screw detergent is low in cost.
Description
Technical field
The invention belongs to chemical field, particularly relate to a kind of screw cleaning agent, specifically a kind of screw cleaning agent and preparation method thereof of injection industry.
Background technology
The screw cleaning agent used in the market has following several:
1. pure in plastic raw materials cleaning needed for white plastic powder or follow-up injection moulding.
2. with tetracol phenixin or the cleaning of toluene class organic solvent.
3. with the cleaning of the strong alkaline aqueous solution such as sodium hydroxide, water glass.
Above three class screw cleaning agents can be used for the screw rod cleaning of different synthetic resin moulding compound, but have a common shortcoming, cost is higher, and cleaning performance is poor.
Summary of the invention:
For above-mentioned technical problem of the prior art, the invention provides screw cleaning agent of a kind of injection industry and preparation method thereof, screw cleaning agent of described this injection industry and preparation method thereof solves the technical problem of the higher and cleaning quality difference of screw rod of the prior art cleaning cost.
The screw cleaning agent of a kind of injection industry of the present invention, is made up of the material of following weight percent:
Polysorbate60 1.0 ~ 2.5%;
Potassium hydroxide 2.0 ~ 4.0%;
Sodium phosphate 0.5 ~ 1.0%;
Tai-Ace S 150 0.1 ~ 0.5%;
Sodium dodecylbenzene sulfonate 0.1 ~ 0.3%;
Water surplus.
Further, described polysorbate60 is Arlacel-60 Soxylat A 25-7, is a kind of nonionic surface active agent.
Further, described water application deionized water, if can produce red-brown ferric hydroxide colloid with tap water, gets clear liquid after waiting until ferric hydroxide precipitate, could obtain the screw cleaning agent of injection industry of the present invention.
Further, the present invention adopts potassium hydroxide, sodium phosphate, is in order to lasting strong basicity, can cleans heavy oil dirt.
Further, the present invention adopts Sodium dodecylbenzene sulfonate as tensio-active agent.
Present invention also offers the preparation method of the screw cleaning agent of above-mentioned a kind of injection industry, comprise the steps: to take each material according to mass ratio, first in water, slowly add potassium hydroxide, rapid stirring is to dissolving completely, then add sodium phosphate, Tai-Ace S 150, polysorbate60 and Sodium dodecylbenzene sulfonate, be stirred to dissolve completely just finished product.
A kind of strong basicity thing of the present invention and tensio-active agent are the screw cleaning agent of raw material, synthetic resin moulding compound and strong alkaline substance, surfactant mixture thing adhesion on molding machine intraperitoneal strong friction, surface, cleaning molding machine abdominal cavity and screw rod.After cleaning, the mixture that this use is crossed can clean in hot water, screw cleaning agent again, then washes three times with clear water, and remaining synthetic resin moulding compound can continue to use.
The present invention compares with prior art, and its technical progress is significant.The present invention solves screw cleaning agent cost and remains high on the basis keeping screw cleaning agent performance, the problem of cleaning performance difference.Enter molding machine after mixing with plastic raw materials needed for white plastic raw material or follow-up injection moulding with a small amount of the present invention, previous injection moulding color can be cleaned up, product cleaning performance of the present invention is good, does not affect follow-up injection moulding work, with low cost.
