Abstract
The invention discloses an ultraviolet curing coating capable of conducting and dissipating heat, the ultraviolet curing coating comprises the following components by mass: 60-80% of photosensitive resin; 3-10% of carbon black; 3-7% of aluminum nitride; 5-7% of boron nitride; 2-7% of alumina; 2-5% of silicon carbide; 5-15% of a reactive type monomer; 5-10% of a photosensitive initiator and 1-3% of an assistant. The ultraviolet curing coating comprises the aluminum nitride, boron nitride, aluminum oxide and silicon carbide which are high thermal conductivity materials, the surface of a substance to be coated is coated with the ultraviolet curing coating, so that a hard protective layer is formed on the surface of the substance to be coated, and heat aluminum nitride and other conductivity matters are used for rapid heat transfer so as to obtain an efficient heat conduction effect.
Description
Technical field
The present invention relates to a kind of UV-light to visible light solidifying material, relate in particular to a kind of ultraviolet-curing paint ultraviolet-curing paint that can heat conduction and heat radiation.
Background technology
Photo-cured coating claims again photoactive coating, the ultraviolet-curing paint that is called that the UV-light of take is the paint solidification energy.UV-light (UV) is coating material solidified does not need heating, can be on the inflammable grounds such as paper, plastics, leather and timber film-forming rapidly.Ultraviolet-curing paint is mainly comprised of photosensitive resin, photosensitizers (light trigger) and thinner, adds some additives simultaneously, as thermo-stabilizer, adds pigment and filler while preparing colored paint.
Photosensitive resin is generally the low-molecular-weight resin with unsaturated link(age), as unsaturated polyester, acrylic oligomers; Photosensitizers is easily to absorb the compound that UV-light produces living radical, as benzophenone, st-yrax alkyl ether; The Main Function of thinner is to reduce dope viscosity, also participates in film-forming simultaneously, is reactive thinner, as vinylbenzene, acrylate etc.
Photo-cured coating advantage is set time short (part second is arrived several minutes), solidification value is low, volatile matter is low, is to economize the energy, resource-saving, nuisanceless, high efficiency coating new variety; Its shortcoming is that free radical type photo-cured coating solidification process is prevented by oxygen, and surface cure is bad.
The method that traditional paint solidification is normally physical dryness by heating is removed the solvent in macromolecular solution, obtains the paint film of sclerosis.It is utilize the energy of UV-light to cause low molecule performed polymer in coating or oligomer and as the polymerization between the monomer molecule of reactive thinner and crosslinking reaction, obtain the paint film that hardens that UV solidifies, and is in fact to realize chemical seasoning by forming chemical bond.
People have also found some problems when using ultraviolet-curing paint, for example traditional photo-cured coating heat conduction and heat radiation ability is poor, uses and requires on the product of quick heat radiating heat conduction at warmer, air-conditioning etc., can not carry out fast heat conduction and heat radiation, heat is concentrated, damaged product.Therefore it is the technology that industry is thirsted for always that a kind of ultraviolet-curing paint that can quick conductive heat radiation is provided.
Summary of the invention
The invention provides a kind of ultraviolet-curing paint that can heat conduction and heat radiation, by the aluminium nitride in coating, boron nitride, aluminum oxide, silicon carbide etc., coated article surface is carried out to heat transmission fast, thus enhance heat heat-conducting effect.
The present invention is achieved by the following technical solutions:
Ultraviolet-curing paint that can heat conduction and heat radiation, component and the mass percent of described photo-cured coating are as follows
Further preferably, described auxiliary agent comprises defoamer and flow agent, and wherein defoamer is silicone based defoamer, and flow agent is that fluorine changes silicon class flow agent; The mass ratio of defoamer and flow agent is 1:1.
Further preferably, described photosensitive resin is urethane resin, comprises aliphatic polyurethane and aromatic urethane.
Further preferably, described response type monomer is selected from tripropylene glycol diacrylate, Viscoat 295, pentaerythritol triacrylate, tetramethylol methane tetraacrylate, tetramethylolmethane six acrylate, Hydroxyethyl acrylate, hydroxyethyl methylacrylate one or more.

In this patent coating, containing aluminium nitride, boron nitride, aluminum oxide, silicon carbide is all high conduction material; by being coated in coated article surface; thereby on its surface, form hard protective layer, by conduction materials such as aluminium nitride, carry out fast heat transmission simultaneously, thereby obtain high-efficiency heat conduction effect.
Embodiment
Below by embodiment, the present invention is further elaborated.
The light curing agent product that the various embodiments described above are made is tested, and result is as follows:
This patent, by the Combinatorial Optimization to the mass percent of aluminium nitride, boron nitride, aluminum oxide, silicon carbide and size, is sneaked into coating by different inorganicss, reduces coating thermal resistance.By the collocation of different-grain diameter size, make to form good heat conductive approach in coating, make radiator element coating formation heat conduction network chain, whole heat conduction effect is best, and the mechanical property of coating also reaches best simultaneously.Those skilled in the art will recognize that; above-mentioned embodiment is exemplary; in order to make those skilled in the art can better understand this patent content; should not be understood as the restriction to this patent protection domain; so long as disclose spiritual do any according to this patent, be equal to change or modify, all falling into this patent protection domain.
