Meanwhile, it has been recalled that the sensing unit 1 may include a motion sensor and a weight sensor. Since these sensors are vulnerable to shock, moisture, and dust, they generally include a housing incorporating each sensor.

However, depending on the material, it is often the case that it does not provide complete protection against various external factors such as moisture, shock, heat, dust, and chemical components. In view of this, the present invention is to provide a method for improving the protection performance of the sensor by providing a protective film on the outer surface of the housing. That is, the present invention is characterized in that the housing may further include a protective film provided by applying and curing a protective agent on the outer surface.

Such a protective film should be easily provided, and must have excellent adhesion, and further, should have improved antiseptic properties, fire resistance, and rust resistance. In addition, there is a need to provide improved manufacturability due to rapid curing, and improved waterproofness through water repellent treatment. .

The protective agent composition for the protective film of the present invention providing the above effects is 100 parts by weight of phenoxyethyl acrylate, 150 to 250 parts by weight of polyester acrylate, 30 to 40 parts by weight of 2,4,6-trimethylbenzoyldiphenylphosphine oxide Parts, 50 to 100 parts by weight of polyvinyl acetate, 1 to 5 parts by weight of 2-methyl-4-isothiazolin-3-one, 25 to 35 parts by weight of silica airgel, 10 to 3-glycidoxypropylmethyldimethoxysilane 25 parts by weight, sodium silicate 30 to 50 parts by weight, hydroxyethyl acrylate 10 to 70 parts by weight, ethyl siliconate 30 to 60 parts by weight, ethylenediaminetetraacetate 1 to 5 parts by weight, tetraethoxysilane 0.5 to 2.5 parts by weight Includes wealth.

For each configuration, first (Phenoxyethylacrylate) phenoxyethylacrylate is used as an acrylate-based monomer, and has been confirmed to be most suitable for the present composition among various acrylate-based monomers because it has adequate flowability and excellent heat resistance. The amount of each composition to be described later will be described based on 100 parts by weight of this phenoxyethyl acrylate.

Next, (Polyesteracrylate) polyester acrylate is used as an acrylate-based oligomer, and has been found to be most suitable for the present composition among various acrylate-based oligomers because it has proper adhesion, strength, and durability. The polyester acrylate is preferably used in an amount of 150 to 250 parts by weight, and when used outside the above numerical range, it has been confirmed that the adhesion, strength and durability of the protective film are significantly reduced. As a result of repeated experiments, the most preferable amount was found to be 200 parts by weight.

Next, (2,4,6-Trimethylbenzoyldiphenylphosphineoxide) 2,4,6-trimethylbenzoyldiphenylphosphine oxide is used as an initiator, and when used together with the above-mentioned phenoxyethyl acrylate and polyester acrylate among various initiators It was confirmed that the best physical properties can be secured. The 2,4,6-trimethylbenzoyldiphenylphosphine oxide is preferably used in an amount of 30 to 40 parts by weight, and when used in less than 30 parts by weight, formation of sufficient radicals is difficult, and when used in excess of 40 parts by weight This is markedly lowered, and when used outside the above composition range, a noticeable decrease in physical properties was observed, especially in curing time and flowability. As a result of repeated experiments, the most preferred amount was found to be 35 parts by weight.

Next, (Polyvinylacetate) polyvinyl acetate is used as a fixing agent that improves the fixing force of the protective agent, and the amount is preferably 50 to 100 parts by weight. For example, when used in an amount of less than 50 parts by weight, there is a problem in that the protective agent is not well adhered due to a decrease in flexibility of the coating film, and when used in excess of 100 parts by weight, the dryness of the protective agent is deteriorated. As a result of repeated experiments, it was found that the optimum amount was 70 parts by weight.

Next, (2-Methyl-4-Isothiazoline-3-one) 2-methyl-4-isothiazolin-3-one is used as a preservative, and the amount is preferably 1 to 5 parts by weight. When used outside the above composition range, there was no apparent problem, but repeated experiments showed the most remarkable effect in the above composition range.

Next, (Silica Aerogel) silica airgel is a composition that serves to enhance fire resistance and heat insulation based on the diffused pores, and is used as a refractory agent and heat insulating agent. Silica aerogel is a material with a very large specific surface area, having a porosity of 80 to 99.87% and a pore size of 1 to 50 nm, and is a transparent ultra-low density material, characterized by high light transmittance and low thermal conductivity, so it has high potential as a transparent insulation material. Have The silica aerogel absorbs moisture, and thus the gel structure properties and physical properties are deteriorated, so that the surface is preferably hydrophobized, and the amount is preferably 25 to 35 parts by weight. When used outside the above composition range, there is a problem in that optimum physical properties cannot be secured, and in particular, when used in excess of 35 parts by weight, a problem of economical efficiency is deteriorated. As a result of repeated experiments, it was found that the most preferable amount was 30 parts by weight.

Next, (3-Glycidoxypropylmethyldimethoxysilane) 3-glycidoxypropylmethyldimethoxysilane is used as a coupling agent to improve physical properties by increasing the interfacial adhesion of each composition, especially polymer compositions, and the amount used is 10 to 25 parts by weight. desirable. When used outside the composition ratio, the binding force between the compositions is not effectively expressed. As a result of repeated experiments, the most preferable amount was found to be 20 parts by weight.

Next, (Sodiumsilicate) sodium silicate is added as a rust inhibitor, there is an advantage of a relatively economical excellent among various rust inhibitor compositions. The preferred amount of sodium silicate is 30 to 50 parts by weight, for example, when it is used less than 30 parts by weight, it is difficult to guarantee the anti-corrosive ability, and when used in excess of 50 parts by weight, there is a problem that economic efficiency is deteriorated. The optimal usage amount considering both economic efficiency and anti-corrosion ability is 40 parts by weight.

Next, (Hydroxyethylacrylate) hydroxyethyl acrylate is added as an adhesion enhancer, and hydroxyethyl acrylate was employed because it has the advantage of being particularly hardenable. The preferred amount of use is 10 to 70 parts by weight, for example, when used in an amount of less than 10 parts by weight, the adhesion promoting effect is not properly expressed, and when used in excess of 70 parts by weight, there is a problem that the volatility increases and the toxicity becomes strong. As a result of repeated experiments, it was found that the most preferable amount was 40 parts by weight.

Next, (Ethylsiliconate) ethylsiliconate is added as a strength strengthening agent to increase the corrosion resistance, impact resistance, scratch resistance (tolerance of scratch / scratch) and surface hardness of the protective film, and the average particle size is 10 to 20 nm. Preferably, the preferred amount is 30 to 60 parts by weight. For example, when used in less than 30 parts by weight, sufficient strength cannot be obtained, and when used in excess of 60 parts by weight, the possibility of cracking after construction increases due to excessive stiffness. As a result of repeated experiments, it was found that the most preferable amount was 40 parts by weight.

Next, (Ehtylenediaminetetracetate) ethylenediaminetetraacetate is used as an adsorption enhancer, and enhances the adhesion by consequently enhancing the adsorption power during the initial construction of the protective film. The preferred use amount of ethylenediaminetetraacetate is 1 to 5 parts by weight, and when used outside the above composition range, the adsorption strengthening effect is not adequately expressed.

Next, (Tetraethoxysilane) tetraethoxysilane is hydrolyzed and condensed to impart waterproofness and water repellency to the protective film and is added to improve antiseptic properties, preferably 0.5 to 2.5 parts by weight is used. The effect of improving waterproofness, water repellency, and antiseptic properties is negligible, and when used in excess of 2.5 parts by weight, there is a problem in that workability is deteriorated. As a result of repeated experiments, the most preferable amount was found to be 2 parts by weight.

The protective film of the present invention having a limitation in the above-described configuration and composition range does not require a drying temperature limitation, and it is easily provided with a protective film because curing is performed quickly without flowability, and further excellent adhesion, as well as improved antiseptic and fire resistance , It has an anti-rust property, and in addition, has the advantage of excellent water resistance.

There was no breakage of the protective film in the interior (breakage rate less than 5%).

Therefore, it was confirmed that Examples 2 and 3 had superior adhesion and strength to the protective film compared to Example 1.

[Experimental Example 3]

As a result of performing an experiment of directly spraying a flame for 10 minutes through a torch on the outer surface of each test block of Examples 1 to 3, some combustion and melting occurred in Examples 1 and 2, but a slight soot occurred in Example 3 However, the protective film did not burn at all.

Therefore, it was confirmed that Example 3 was superior in fire resistance and heat insulation compared to Examples 1 and 2.

[Experimental Example 4]

After spraying water on the outer surface of each of the test blocks for Examples 1 to 3 for 6 hours, a small amount of moisture was detected in Examples 1 and 2 as a result of removing the protective film and examining the internal invasiveness of the test blocks. At, no moisture was detected.

Therefore, it was confirmed that Example 3 was superior in water resistance compared to Examples 1 and 2.
