Description

CURTAIN CURING SHEET FOR BUILDING AND MANUFACTURING METHOD THEREOF}

The present invention relates to a construction badge reinforcement membrane (protective film) and a method for manufacturing the same, in particular, by fixing the badge reinforcement membrane to the external scaffolding of the construction at the construction site, it is possible to protect the construction from outside temperature, wind and sun, and also construction The present invention relates to a construction curtain retaining membrane capable of securing aesthetics of a site and a method of manufacturing the same.

After finishing the concrete, the concrete needs sufficient protection against harmful effects such as temperature, load, impact, fouling, breakage, etc., which is called curing or maintenance. It is no exaggeration to say that the quality of concrete depends on curing after construction, so curing or maintenance should be carried out as a serious final work of concrete construction.

As a conventional reinforcement film, a thin sheet having a thickness of about 0.3 to 0.8 mm is used as the reinforcement film. However, the reinforcement film only plays an aesthetic role of blocking dust or masking dirt inside. However, in the case of using the reinforcement membrane, both summer and winter may not be effective for curing concrete.

For example, in summer, when the concrete is cured, the external heat is transferred to the inside, thereby deteriorating the quality of the concrete, which may be a cause of poor construction. That is, in summer, the heat of hydration in the concrete is increased due to external hot air and direct sunlight, and the moisture on the surface of the concrete rapidly evaporates, thereby degrading the quality of the concrete. Since the strength of the lowered can not be expected to increase the long-term strength may result in a decrease in durability. In contrast, the expensive film curing agent has a certain effect on preventing moisture evaporation of the concrete, but there is a disadvantage that the quality degradation due to the temperature rise of the concrete is not prevented.

In winter, when concrete is poured, it is mixed with concrete, cold-resistant, etc. to prevent the initial damage of the East Sea, or curing by using heater and lignite for curing. Being less than 20% economically costly, the fuel used for heating continuously releases carbon dioxide and is not environmentally effective. In addition, when the conventional reinforcement film is used, the strength expression of the concrete is delayed and the construction period becomes longer, which may cause economic losses.

In contrast to the conventional rejuvenation film, there is Korea Patent Publication No. 2008-112854 (published on December 26, 2008). The Korean Laid-Open Patent relates to a "multi-functional retentive tent", which is intended to prevent tearing or breakage of the tent by an external environment, to provide a warming effect and dimming during daytime work, and is a woven weave between the upper and lower membranes. Providing a wealth, and put the rope along the outer periphery of the tent, characterized in that the end is folded to sew. Transparent film was used to prevent darkening of the work space and to form a weave inside to increase the durability of the tent. However, it is not possible to solve the problems caused by the initial East Sea during the curing of the concrete because it is not possible to provide a warming effect in winter, etc. Also, when connecting a tent and a tent, a rope must be connected to the eyelet one by one, so there is a problem of poor workability. .

The present invention has been made to solve the above-mentioned problems of the prior art, and an object thereof is to provide a badge retentive film and a method for manufacturing the same, which have improved thermal insulation, insulation and durability.

In addition, it is an object of the present invention to provide a badge supplement film and a method of manufacturing the same that can reflect external direct sunlight.

In addition, since the resin mesh and the bubble sheet portion are integrally formed as a synthetic resin, the bonding strength is also high, the production is very easy, and the mass production is advantageous. In addition, since both the resin mesh and the bubble sheet portion can be bonded by heat or fusion, heat insulation or fusion can be connected to each other, and the gap between the connected insulation films can be completely sealed to insulate in winter. The effect can be raised significantly.

The bubble sheet portion and the resin mesh may be formed of a material capable of forming a film or filament. For example, synthetic resins such as polyethylene (PE), polypropylene (PP), and polyethylene terephthalate (PET) may be used. In addition, the bubble sheet portion and the resin mesh may impart transparent, translucent or opaque properties. This may vary depending on the nature of the season or the working environment.

In addition, the bubble sheet may further include a reflective film such as a metal foil or a deposition film to block direct sunlight.

At this time, the resin mesh may be introduced into the roller together with the synthetic resin in the liquid phase, and may be formed integrally with the resin mesh while the synthetic resin passing through the roller is cured.

The film formed integrally with the resin mesh may be an upper film, a lower film, or an intermediate layer film of the bubble sheet constituting the bubble sheet portion, and is integrally attached to another bubble sheet or bubble film while passing through the roller forming apparatus to form the bubble sheet portion. can do. At this time, the bubble sheet passing through the roller forming apparatus may be provided in one or more.

The reinforcement film of the present invention may be formed using a transparent film material, and includes a bubble sheet portion in which a plurality of air pockets are formed therein, thereby improving the thermal insulation effect. In addition, since the bubble sheet portion is formed integrally with the resin mesh, the durability can be improved, and of course, both the resin mesh and the bubble sheet portion can be thermally fused, so that the resilient film can be subsequently formed without a gap.

Since the reinforcement film of the present invention may further include a reflective film and an opaque colored film, in addition to the above-described heat insulation effect, it is possible to add a characteristic capable of reflecting or adjusting external direct sunlight. When using the retentive membrane of the present invention was expected to be 50% or more of the results of the thermal insulation rate (KS K 0560: 2006 constant temperature method) experiment.
