Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to flame retardant carpet backing adhesive compositions.

Specifically, it is a flame-retardant carpet lining adhesive composition mainly consisting of polymer latex and clay.

In recent years, as lifestyles have changed, carpets have been introduced into homes and public places such as offices, hotels, hospitals, schools, and libraries.They have excellent heat retention, soundproofing, and dustproofing properties, as well as rich colors and a luxurious feel. K has been introduced one after another as an interior design with a In addition, as carpets in a wide variety of forms have appeared on the market, the pile or backing material has been specially processed to have stain-proof, insect-proof, anti-bacterial, anti-static, or odor-proof properties. It is getting to the point where it can no longer be called furniture.

Particularly in public places, it cannot be overstated that the use of shingle finishing has a great effect on giving the building as a whole a sense of luxury as well as practicality.

However, because of the tight finish, there have been cases where a fire source comes into contact with the carpet, ignites it, and then the car vent itself becomes the source of fire and spreads, resulting in a catastrophe.9
Possibility to grow became a dog. On November 1, 1971, carpets and other floor coverings became subject to flame-retardant regulations, and the Fire Service Act Enforcement Order was amended and came into effect on July 1, 1974. For this reason, those skilled in the art have tried to improve the flame retardant properties of the carpet as a whole by applying flame retardant treatment to the pile, using pile materials that do not easily burn, or incorporating flame retardants into the backing adhesive composition. is sharpening.

As a result of repeated tests, the defectors have found that an adhesive composition mainly using polymer latex and clay can provide carpets with extremely superior flame retardant properties, and that blisters do not form when the carpet dries. The present invention was completed by discovering that there are very few.

Examples of the polymer latex used in the present invention include styrene-butadiene copolymer latex, methyl methacrylate-butadiene copolymer latex, polybutadiene latex, acrylonitrile-butadiene copolymer latex, acrylonitrile-styrene-butadiene copolymer latex, and ethylene. - Vinyl acetate copolymer latex, ethylene-vinyl chloride copolymer latex, vinyl chloride polymer latex, vinylidene chloride polymer latex, vinyl chloride-acrylate copolymer latex,
Examples include chloroprene. These latexes may contain carboxyl groups, hydroxyl groups, N-methylol groups, amide groups, glycidyl groups, etc. These polymer latexes may be used alone or in combination of two or more.

The clay used in the present invention is mainly composed of silicon, aluminum, and water molecules, and also contains iron, alkali metals,
It is composed of alkaline earth metals, etc., and is an aggregate of naturally occurring fine particles that exhibits plasticity when mixed with water and rigidity when dry. Typical examples include those with a hexagonal plate-like crystal structure such as kaolinite and detsuite, kaolin minerals with a tubular structure such as shattered halloysite, and sericite, which has a flat plate-like structure also called sericite. , pyrophyllite with irregular plate-like structure, irregular plate-! or clay minerals such as montmonlonite, which have a spherical structure.

These may be used alone or in combination of two or more.

The clay is used in an amount of 50 to 800 parts by weight, preferably 100 parts by weight, based on 100 parts by weight of the polymer latex solid content.
500 parts by weight. If it is less than 50 parts by weight, the flame retardant properties and blister resistance will be poor, and if it exceeds 800 M parts, the effect rJ will not increase.

Preservatives, colorants, thickeners, antistatic agents and inorganic fillers such as calcium carbonate can be used.

EXAMPLES The present invention will be specifically explained below with reference to Examples, but the present invention is not limited in any way by the Examples.

Margin Example 1 An adhesive composition having the composition shown in Table 1 was prepared, and the pile was made of polyester and the pile length was 7 mm, and a solid content of 10ooy was applied uniformly to the back surface of a 1 inch 0 gauge cut pile carpet Vc1 nX. 7 ounce jute was crimped.

Flame retardant: The wet carpet was dried at a temperature of 120° C. for 25 minutes. The obtained processed fabric was subjected to all flame retardant performance tests for floor coverings in accordance with Article 4-3 of the Fire Service Act Enforcement Regulations. Table the results.

Side 1 Blistering: Undried carpet was measured at a total U degree of 170 and judged according to the following grades.

No occurrence of first-class niblisters was observed.

There are many class 8 niblisters on the entire surface.

The results are shown in Table-2.
