Description

Technical Field

[0001] The invention relates to a high-temperature wear-resistant polyazine naphthyl ether ketone resin containing a siloxane structure and a preparation method thereof, belonging to the technical field of polymer material science. Background Art

[0002] Polyazine naphthalene ether ketone resin is a new type of engineering plastic with excellent properties, including strong acid resistance, corrosion resistance, high temperature resistance and insulation. Polyazine naphthalene ether ketone resin is widely used in materials such as coatings, films and fibers. Polyazine naphthalene ether ketone resin is a multi-group multi-heterocyclic polymer prepared from polyazine naphthalene bisphenol monomers through a mild reaction process. The introduction of polyazine naphthalene ether ketone structure effectively expands the steric hindrance between molecular chains and reduces the mobility of molecular chains. At the same time, the polyazine naphthalene ether ketone structure distorts the main chain molecular chain, increases the molecular weight, and causes the molecular chain to entangle.

[0003] Polyazine naphthoxy ether ketone resin has heat resistance, mechanical properties and electrical properties. The most prominent feature is its high temperature resistance. Its glass transition temperature can be as high as 300°C, which can be applied to some high-temperature scenes. The surface friction coefficient of polyazine naphthoxy ether ketone resin is 0.5-0.6, and the wear rate is 10-12×10 -14 m 3 ·N-1·m-1. As the number and distance of friction increase, the friction heat increases, the surface of the polyazine phthalone resin softens and bonds, resulting in increased friction, easy breakage of the resin, and large quality loss.

[0004] Organic ceramic resin is called dimethyl silicone oil or polydimethylsiloxane, which is a polymer composed of silicon and oxygen atoms. It has inertness, high temperature stability, cold resistance, wear resistance, low surface tension and self-lubricating properties. Organic ceramic resin can be used as a lubricant, heat insulator, and moisturizer. Depending on the branched structure and degree of polymerization, the various properties are different.

[0005] In order to further improve the comprehensive performance and expand the application scope of polyazonaphthyl ether ketone resin, the research on the modification of polyazonaphthyl ether ketone polyether sulfone ketone has been continuously deepened. Polyazonaphthyl ether ketone resin is blended with polystyrene, and an ultrafine fiber membrane is produced by electrospinning process, and the strength of the product is significantly improved. Other materials that have been studied and can be used in the field of polyazonaphthyl ether ketone resin modification include polyethylene terephthalate, silane coupling agent, liquid crystal polymer, multi-walled carbon nanotube, carbon fiber, glass fiber, etc. In addition, polyazonaphthyl ether ketone resin can also be used to modify other polymer materials, such as to modify epoxy resin, so that the glass transition temperature of the product is greatly increased.

[0006] In order to adapt to the wear resistance under high temperature conditions, such as the application field of grate plates in the field of waste incineration, it is necessary to obtain a certain wear resistance for the resin material protecting the substrate under the temperature of 300-400°C. The modification technology of organic ceramic resin using polyazonaphthyl ether ketone resin has the high temperature resistance of polyazonaphthyl ether ketone resin, further improves the temperature resistance, increases the wear resistance of its surface under high temperature conditions, and also has a self-lubricating effect. Summary of the invention

[0007] In order to improve the wear resistance of polyazonaphthalene ether ketone resin under high temperature conditions, the present invention provides a high-temperature wear-resistant polyazonaphthalene ether ketone resin containing a siloxane structure and a preparation method thereof.

[0008] According to one aspect of the present invention, a high-temperature wear-resistant polyazonaphthyl ether ketone resin containing a siloxane structure is provided. The high-temperature wear-resistant polyazonaphthyl ether ketone resin containing a siloxane structure is obtained by using a polyazonaphthyl ether ketone polymer as a matrix and end-capping with a functional group chloropropane, and then grafting the modified polyazonaphthyl ether ketone with an organic ceramic resin through a coupling agent.

[0009] Furthermore, the high-temperature wear-resistant polyazine naphthyl ether ketone resin containing a siloxane structure comprises the following raw material components in parts by weight: 100 parts of polyazine naphthyl ether ketone polymer, 20 parts of functional group chloropropane, 5 parts of coupling agent and 30 parts of organic ceramic resin.

[0010] Furthermore, the molecular weight of the polyazine naphthyl ether ketone polymer is 12,000.

[0011] Furthermore, the functional group chloropropane is epoxy chloropropane.

[0012] Furthermore, the coupling agent is any one of nitrogen-(2-aminoethyl)-nitrogen'-[3-(trimethoxysilyl)propyl]-1,2-ethylenediamine, γ-glycidyloxypropyltrimethoxysilane, N-(beta-aminoethyl)-gama-aminopropyltrimethoxysilane, and 3-aminopropyltriethoxysilane.

[0013] Furthermore, the molecular weight of the organic ceramic resin is 20,000.

[0014] According to another aspect of the present invention, a method for preparing a high-temperature wear-resistant polyazine naphthyl ether ketone resin containing a siloxane structure is provided, which is used to prepare the above-mentioned high-temperature wear-resistant polyazine naphthyl ether ketone resin containing a siloxane structure, comprising the following steps:

[0015] S1. Take the polyazine naphthyl ether ketone polymer and the functional group chloropropane according to the predetermined mass fraction, add them to the solvent of acetone and DMSO under the protection of nitrogen, and then add K 2 CO3 ;

[0016] S2, adding chloroform to the mixture in step S1 to obtain a precipitate, and filtering and drying the precipitate;

[0017] S3, adding PCDL to the solid precipitate obtained in step S2 and stirring, and adding a coupling agent while stirring;

[0018] S4, taking distilled water and potassium hydroxide and mixing them evenly, adding them to the reactant obtained in step S3, and adding organic ceramic resin to mix;

[0019] S5, filtering and drying the mixture of step S4 to obtain the high-temperature wear-resistant polyazine naphthyl ether ketone resin containing a siloxane structure.

[0020] Furthermore, in step S1, the polyazine naphthyl ether ketone polymer, the functional group chloropropane, K 2 CO 3 The mass parts of are: 100 parts, 20 parts, 35 parts respectively; the mass parts of PCDL in step S3 are 30 parts, and the coupling agent is 5 parts; the mass parts of distilled water, potassium hydroxide, and organic ceramic resin in step S4 are: 50 parts, 1-2 parts, 30 parts respectively.

[0021] Furthermore, the reaction conditions of step S1 are a reaction temperature of 100°C and a reaction time of 12-16 hours; the drying method of step S2 is vacuum drying at 80°C for 36 hours; the reaction conditions of step S3 are maintaining the temperature at 50°C for 12 hours; the reaction conditions of step S4 are heating to 80°C, stirring, and maintaining the reaction for 10 hours; and the drying conditions of step S5 are vacuum drying at 60°C for 12 hours.

[0022] The beneficial effects of the present invention are embodied in:

[0023] 1) Grafting an organic ceramic resin with wear resistance and temperature resistance onto a polyazanaphthyl ether ketone resin by chemical means, thereby achieving the purpose of high temperature wear resistance. The technical route is to modify the surface of the polyazanaphthyl ether ketone resin with a functional group chloropropane to obtain an active group-terminated resin; a coupling agent is used to shrink the polyazanaphthyl ether ketone resin with an active group-terminated polyazanaphthyl ether ketone resin to obtain a coupling agent-terminated polyazanaphthyl ether ketone resin; on this basis, the coupling agent-terminated polyazanaphthyl ether ketone resin is grafted and modified with an organic ceramic resin, and finally a polyazanaphthyl ether ketone resin containing a siloxane structure is obtained, which can achieve wear resistance under high temperature conditions, achieve surface self-lubricating properties, and improve the problem of surface quality loss of polyazanaphthyl ether ketone resin during repeated friction under high temperature conditions; at the same time, its heat resistance is further improved, and its glass transition temperature is increased from 300°C to 400°C, or even higher. This also provides a technical solution for the environmental modification of this type of high temperature resistant resin. The resin can be suitable for the performance of repeated friction and pressure friction in some high temperature environments, and can be used on some substrate-protected resin films or on the surface of other protective substrates.

[0024] 2) The preparation method of the high-temperature wear-resistant polyazine naphthyl ether ketone resin containing a siloxane structure, with a polyazine naphthyl ether ketone polymer as a substrate, and a molecular weight of 12,000. The substrate resin can give electrons in a weakly alkaline state, and the functional group chloropropane is used as an electron acceptor to realize the connection of the functional group on the polyazine naphthyl ether ketone resin. The connection of the functional group chloropropane can be achieved by controlling the number of polyazine naphthyl monomers and performing different end-capping techniques on the resin, thereby realizing the resin multi-end-capping technology of the functional group chloropropane. The functional group can be grafted with an organic ceramic resin by a coupling agent. Under the reaction conditions, a coupling agent containing an active hydrogen group reacts with a polyazine naphthyl ether ketone resin containing a functional group to obtain a coupling agent-grafted polyazine naphthyl ether ketone resin. The above resin is subjected to a modified grafting reaction with an organic ceramic resin, and the molecular weight of the organic ceramic resin is about 20,000. Through the grafting technology of the organic ceramic resin, the glass transition temperature of the polyazine naphthyl ether ketone resin is improved and the wear resistance in a high temperature environment is achieved.

[0025] In summary, the present invention uses a polyazine naphthyl ether ketone polymer as a matrix and performs end-capping modification with a functional group chloropropane, and then uses an organic ceramic resin as a coupling agent to carry out a grafting reaction on the modified polyazine naphthyl ether ketone, so as to improve the wear resistance of the resin matrix under high temperature conditions. The obtained polyazine naphthyl ether ketone resin containing a siloxane structure has wear resistance and mechanical properties under high temperature conditions, and has the functions of high temperature resistance, wear resistance, self-lubrication and resistance to chemical media.
