Description

[Detailed description of the invention]

This invention relates to flame retardant tufted carpet backing adhesive compositions. More particularly, the present invention relates to a flame retardant tufted carpet backing adhesive composition comprising zeolite to a polymeric latex. In recent years, as lifestyles have changed, carpets have been introduced into homes and public places such as offices, hotels, hospitals, schools, libraries, etc., with their excellent heat retention, soundproofing and dustproofing properties, as well as their rich colors and luxury. It began to be introduced one after another as an interior design with a sense of style. In addition, a wide variety of carpets have appeared on the market, with piles or backing materials treated with special treatments to make them stain-proof, insect-proof, anti-bacterial, anti-static, or odor-proof. However, the situation is becoming increasingly difficult. 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 tightening process, there is a high possibility that a fire source may come into contact with the carpet, ignite it, and then the carpet itself becomes a source of fire, causing the carpet to spread and cause a catastrophe. On November 1, 1973, floor coverings such as carpets became subject to flame-retardant regulations, and the Fire Service Act Enforcement Order was revised and came into effect on July 1, 1974. Therefore, among those skilled in the art, fireproofing is applied to the pile.
The flame retardant properties of the carpet as a whole are improved by using pile materials that do not easily burn or by incorporating flame retardants into the backing adhesive composition. As a result of extensive studies, the present inventors have found that an adhesive composition containing a specific amount of zeolite in a polymer latex can impart extremely excellent flame retardant properties to tufted carpets, and at the same time provide tufted carpets with excellent flame resistance. The present invention was completed based on the discovery that the occurrence of blisters when drying carpet is extremely low. Polymer latexes 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,
Examples include ethylene-vinyl chloride copolymer latex, vinyl chloride polymer latex, vinylidene chloride polymer latex, vinyl chloride-acrylate copolymer latex, and chloroprene. These latexes contain carboxyl groups, hydroxyl groups, N
- May contain a methylol group, an amide group, a glycidyl group, etc. Further, these polymer latexes may be used alone or in combination of two or more. The main chemical components of the zeolite used in the present invention are
SiO ₂ , Al ₂ O ₃ , Fe ₂ O ₃ , CaO, Na ₂ O, K ₂ O and
It is H ₂ O, and its composition varies depending on the region of production. Zeolite 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 solid content of the polymer latex.
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 parts by weight, the effect will not increase. The tufted carpet backing adhesive of the present invention generally contains added emulsifiers, stabilizers, dispersants, anti-aging agents, vulcanizing agents, vulcanization accelerators, cross-linking agents,
Defoamers, 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. Example 1 An adhesive composition having the composition shown in Table 1 was prepared, and 1000 g of solid content per 1 m ² was uniformly applied to the back side of a 1/10 inch cut pile carpet with a polyester pile and a pile length of 7 mm. I crimped the ounce jute. Flame retardant: Undried carpet was dried at a temperature of 120°C for 25 minutes. The obtained processed fabric was subjected to a floor covering flame retardant performance test in accordance with Article 4-3 of the Fire Service Act Enforcement Regulations. The results are shown in Table-2. Blister resistance: Undried carpet at a temperature of 170℃
It was dried for 3 minutes using a dryer with a hot air speed of 20 m/sec, and the blisters generated were observed with the naked eye and judged according to the following grades. Grade 1: No blistering was observed. ~ Grade 8: Many blisters occur on the entire surface. The results are shown in Table-2.

It is described in [Table].
