Description

Dust-proof and Insect Repellent Frame

The present invention relates to a dustproof and insectproof frame, and more particularly, to a dustproof and insectproof frame in which a square pipe is formed on the inner surface of an aluminum frame and a mesh surrounds the square pipe.

In general, windows and doors are mounted on a window frame to be able to open and close, and an insect screen is installed to prevent pests such as mosquitoes from entering the room when the window is opened.

These insect screens are installed in various structures depending on the type of window, and an insect screen made of a roll screen is installed on a casement window that is opened to the indoor or outdoor side like a project window, and a rail structure is installed on the sliding window opening and closing by inserting the window pane into the rail. An insect screen is mounted on a screen frame made of

These insect screens are made of a metal or synthetic resin frame with a metal or synthetic fiber as a fabric, and the insect screen is mounted on the insect screen to prevent the inflow of pests and only allow air circulation. In many cases, dust, yellow dust, etc. are mixed, but the conventional insect screen does not perform the filtering and blocking functions of fine dust, which are harmful substances with very small particles.

In other words, when harmful substances such as fine dust enter the room through the insect screen, there is a problem that causes respiratory diseases and skin diseases. It has to be a secondary measure, not a way to prevent it in advance.

Therefore, recently, an insect screen with a fine dust filtering function while basically performing the function of an insect screen to block pests has been proposed. In this state, it is difficult to install, and it must be selected and installed in the process of selecting building materials.

In other words, in the state in which the windows are already installed, the existing insect screen must be removed and a new insect screen with a fine dust filtering function must be manufactured. Even in the case of aluminum and metal windows, since they are manufactured by welding, it is structurally difficult to directly apply to already installed windows, and replacement construction is very difficult, and even if they are replaced, the cost is very expensive.

In addition, in order for the insect screen to have a dustproof function, that is, to block harmful substances with small particles such as fine dust or yellow sand, the structure of the net must be very dense. Therefore, in the season when there is no fine dust or yellow dust, there is a risk of making the indoor space cloudy.

On the other hand, the function of the anti-crime screen is a screen designed and manufactured to withstand strong impact from the outside, and it has a function to block the intrusion from the outside because the screen is not separated or damaged. This is possible.

On the other hand, as shown in Figure 1, Korean Patent Application Laid-Open No. 2019-0139065 discloses a bracket; a bracket coupling part to which the bracket is fastened; and a mosquito net installed between the bracket and the bracket coupling part; a downward protrusion on the left side of the bracket is fastened to an upward protrusion on the left wall of the bracket coupling part, and a left deflection protrusion at the bottom of the left side of the bracket It provides an improved window frame structure, characterized in that it is in contact with the right-facing projection of the lower wall of the bracket coupling portion, and the insect screen is fitted between the downward projection and the upward projection and between the left-handed projection and the right-facing projection.

However, the structure is complicated, and the existing window frame structure, which uses a sealing agent to fix the insect screen and miters the edge of the frame, still cannot be changed.

In addition, although the structure is complicated in the prior art, it has a structure that a user cannot directly attach or detach, and thus maintainability is poor.

As an embodiment, the fixed frame 10 further includes a fine dust meter installed to measure the outdoor fine dust concentration.

In addition, the fixed frame 10 further includes a power supply unit installed to supply power to the fine dust meter, and the power supply unit is a solar power module that generates power by a charged battery or sunlight. either one can be made.

The fine dust measuring device may use a normal fine dust measuring device capable of transmitting and receiving, and the power supply unit may be formed of a battery charged with power or a photovoltaic power generation module that generates power by sunlight.

For example, a light scattering type fine dust meter includes a light source; a photodiode measuring scattered light scattered by the light emitted from the light source collides with fine dust; The photodiode measures the scattered light of the fine dust colliding with the light of the light source.

Alternatively, the light scattering type fine dust meter includes a transmitter that outputs a pulsed laser, a reflective mirror that reflects the pulsed laser including at least two reflective surfaces, a driving unit that rotates the reflective mirror, and a reflective surface of the reflective mirror. It includes a path control mirror that reflects the pulse laser so as to form a path, and a receiver that receives the light reflected through the reflection mirror and converts it into an electrical signal.

Here, since the nanoweb is formed of a material with high spontaneous polarization, when the insect screen 15 passes between dipoles (dipoles), a + charge is located on one surface of the insect screen 15, and a - charge is polarized on the other surface. .

On the other hand, the protective agent composition for a protective film for protecting the fixed frame 10, etc. is 100 parts by weight of phenoxyethyl acrylate, 150 to 250 parts by weight of polyester acrylate, 2,4,6-trimethylbenzoyldiphenylphosphine oxide 30 ~ 40 parts by weight, polyvinyl acetate 50 ~ 100 parts by weight, 2-methyl-4-isothiazolin-3-one 1 ~ 5 parts by weight, silica airgel 25 ~ 35 parts by weight, 3-glycidoxypropylmethyldimethoxy 10 to 25 parts by weight of silane, 30 to 50 parts by weight of sodium silicate, 10 to 70 parts by weight of hydroxyethyl acrylate, 30 to 60 parts by weight of ethylsiliconate, 1 to 5 parts by weight of ethylenediaminetetraacetate, 0.5 parts by weight of tetraethoxysilane -2.5 parts by weight.

The phenoxyethyl acrylate has the characteristics shown in Table 1 below, so it is an optimal material for a protective film.

For each composition, first, phenoxyethylacrylate is used as an acrylate-based monomer, and since it has adequate flowability and excellent heat resistance, it was confirmed that it was most suitable for this composition among various acrylate-based monomers.

In particular, as shown below, the POEA-PAM copolymer (three sets of 2-phenoxyethyl acrylate (POEA)-polyacrylamide (PAM) copolymers) has a better protective effect.

Next, 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 appropriate adhesion, strength and durability. It is preferable that 150 to 250 parts by weight of the polyester acrylate is used, and it was confirmed that the adhesion, strength and durability of the protective film were remarkably reduced when used outside the numerical range. As a result of repeated experiments, it was confirmed that the most preferable amount of polyester acrylate used was 200 parts by weight.
