Abstract
The invention relates to a high cost performance POM, comprising the following ingredients: 65-97 wt% of polyformaldehyde (POM), 2.5-30 wt% of plasticizer, 0.3-1.0 wt% of thermosetting resin, 0.3-1.0 wt% of anti-oxidant 168, 0.4-1.0 wt% of stabilizing agent, and 0.1-0.5 wt% of active carbon. By adding the reagents, the plastic produced by using the POM has high heat resistance, high mechanical strength, and high electric insulativity.
Description
Technical field
The present invention relates to a kind of organic polymer composite, more particularly, relate to a kind of high sexual valence POM.
Background technology
Polyoxymethylene formal name used at school polyoxygenated polyoxymethylene (being called for short POM) is claimed match steel, Trane again.It is to be the polymerizable raw material gained with formaldehyde etc.POM-H (POM-H Acetal homopolymer), POM-K (polyacetal copolymer) is the thermoplastic engineering plastic of high-density, high-crystallinity.Have good physics, machinery and chemical property, excellent crocking resistance is especially arranged.Polyoxymethylene is a kind of smooth surface, and glossiness hard and fine and close material is yellowish or white, can be at life-time service in the-40-100 ℃ temperature range.Its wear resistance and self lubricity are also superior than most engineering plastics, and good oil resistant is arranged again, anti-superoxide performance.Very not acidproof, the radiation of not anti-highly basic and non-UV resistant.POM has better comprehensive performance; Be the hardest in thermoplastics, be in the plastic material mechanical property near one of kind of metal, its tensile strength, flexural strength, fatigue resistance; Wear resistance and electrically all very good, can spend-40--life-time service between 100 degree
But exist weak point to be: by corroded by strong acid, anti-marquis is poor, poor adhesion, and thermolysis and softening temperature are approaching, and limited oxygen index is little.They are widely used in automotive industry, electronic apparatus, mechanical means etc.Can also do water tap, frame window, wash basin.
Summary of the invention
In order to overcome above-mentioned defective, the present invention provides a kind of production and easy to use, the improvement toughness environmental protection polyoxymethylene raw material that cost performance is high.
Technical scheme provided by the invention is following: high sexual valence POM, by following composition by weight forming polyoxymethylene (POM): 65-97%; Softening agent: 2.5-30%, thermosetting resin: 0.3-1.0%, oxidation inhibitor 168:0.3-1.0%; Stablizer: 0.4-1.0%, gac: 0.1-0.5%.
High sexual valence POM raw material production flow process of the present invention is: with POM with being made into about 30% the aqueous solution; Add in the reaction kettle; At this moment; Temperature in the reaction kettle is controlled at 45～55 ℃ and evenly stir being set under the normal pressure; When stirring, slowly add a certain proportion of softening agent, thermosetting resin, oxidation inhibitor, stablizer; After reaction finishes,, can obtain 50% POM salt brine solution with active carbon purifying, filtration.Salt-forming reaction is thermopositive reaction, recirculated water cooling beyond the reaction heat must be removed for this reason, and is oxidized for preventing that nylon salt from contacting with air simultaneously, in production system, fills with nitrogen protection.Under vacuum state, the POM salt brine solution with 50% through evaporation, dehydration, concentrate, crystallization, drying, can obtain solid POM.
Wherein, the adding of some reagent can be so that the plastics of processing have high-performance, and the adding of thermosetting resin can be so that finished product has thermotolerance; Owing to can produce chemical transformation after the heating, hardened forming is heated and does not also soften gradually; Can not dissolve, and pressurized is not yielding; Strong, the electrical insulation capability of the machinery that the adding of softening agent can improve plastics.
The advantage of the high sexual valence POM of the present invention: through the adding of several reagent; Can be so that the plastics of processing with POM have the high heat resistance ability; High mechanical strength; And high electric insulation performance; In addition; Materials procurement convenience of the present invention, production, easy to use, and cost performance is high, the comprehensive like this competitive power of POM on market that improved.
Embodiment
Below be the most preferred embodiment of high sexual valence POM raw material of the present invention, therefore do not limit protection scope of the present invention.
Embodiment one, and a kind of high sexual valence POM raw material is provided, by following composition by weight forming polyoxymethylene (POM): 68%, softening agent: 30%, thermosetting resin: 0.8%, oxidation inhibitor 168:0.5%, 0.4:0.4-1.0%, gac: 0.3%,
With POM with being made into about 30% the aqueous solution; Add in the reaction kettle; At this moment; Temperature in the reaction kettle is controlled at 45～55 ℃ and evenly stir being set under the normal pressure; When stirring, slowly add a certain proportion of softening agent, thermosetting resin, oxidation inhibitor, stablizer; After reaction finishes,, can obtain 50% POM salt brine solution with active carbon purifying, filtration.Salt-forming reaction is thermopositive reaction, recirculated water cooling beyond the reaction heat must be removed for this reason, and is oxidized for preventing that nylon salt from contacting with air simultaneously, in production system, fills with nitrogen protection.Under vacuum state, the POM salt brine solution with 50% through evaporation, dehydration, concentrate, crystallization, drying, finally just can obtain solid POM.
The above; It only is the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
