Functional cotton spray composition, method for producing the same, and building material using the same

Abstract

A functional cotton spray composition includes: 100 parts by weight of cotton fibers having a length of 3 mm or less; 0.5 to 5 parts by weight of a phase change material; 0.5 to 1 parts by weight of a titanium dioxide photoactive catalyst; 0.5 to 2 parts by weight of at least one natural pigment selected from the group consisting of a pine needle powder, a green tea powder, a mugwort powder, an indigo plant powder, a gardenia powder, a charcoal powder and a yellow soil powder; 0.5 to 5 parts by weight of a dispersant; 5 to 20 parts by weight of a viscosity improver; 10 to 20 parts by weight of an organic flame retardant; 5 to 15 parts by weight of an inorganic flame retardant; 0.5 to 3 parts by weight of an antimicrobial and antifungal agent; and 300 to 600 parts by weight of viscosity-controlling water.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a functional cotton spray composition which is mainly composed of short cotton fibers generated when processing an environmentally-friendly raw cotton material or cotton fibers and which is added with not only a microcapsule type phase change material capable of effectively storing the thermal energy transferred to the cotton spray composition during a heating or cooling process so that a heat retention effect or a cold energy retention effect can last for more than a specified time period after the heating or cooling process but also an environmentally-friendly material harmless to human bodies and capable of creating a pleasant indoor environment, when the cotton spray composition is used as a construction-purpose spray material or a building material. The present invention is also directed to a method for producing a functional cotton spray composition and a building material using a functional cotton spray composition....

AI Technical Summary

Benefits of technology

The present invention provides a functional cotton spray composition that can store and release heat or cold for a long time period after being heated or cooled. The composition includes short cotton fibers, a microcapsule type phase change material, a titanium dioxide photoactive catalyst, a dispersant, a viscosity improver, an organic flame retardant, an inorganic flame retardant, an antimicrobial and antifungal agent, and a binding and curing agent. The composition can be used as a building material that promotes energy efficiency and creates a pleasant living environment. The invention also provides a method for producing the functional cotton spray composition.

Problems solved by technology

Such spray-coating materials are, however, insufficient in deriving a beautiful color required in a finishing material and demonstrating a compact shape and an interior decoration effect.

The spray-coating materials are harmful to human bodies and cannot be regenerated.

When incinerated or buried, the spray-coating materials may become a cause of environmental pollution.

This may possibly lead to an overheating problem and a heat loss caused by ventilation or door opening and closing.

In case of cooling, failure to evenly control an indoor temperature results in an increased sense of unpleasantness.

If a cooling device is heavily operated to avoid such a situation, it becomes difficult to save energy.

Due to the absence of functional additives, however, the short-fiber composition fails to provide a satisfactory cooling or heating effect when it is used as a building material in the wall, ceiling or floor.

Although some of the additives contained in the short-fiber composition are environmentally friendly, most of them are synthetic materials harmful to human bodies.

Thus, it is still unsatisfactory to use the short-fiber composition as a building material for creating a pleasant living environment.
