〔産業上の利用分野〕
本発明は、紙や布帛等（以下、基材と言う。）にホット
メルト接着材を散布し加熱接着して樹脂皮膜を形成する
ラミネート法に関するものである。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a lamination method in which a hot melt adhesive is sprayed on paper, fabric, etc. (hereinafter referred to as the base material) and bonded by heating to form a resin film. It is related to.
この種のラミネート法は、車両用カーペットのパイルと

への通用が試みられている。This type of lamination method is commonly used for bonding the backing between the pile of vehicle carpets and the base fabric, and has recently been used for finishing the back side of vehicle interior fabrics such as vehicle upholstery, wall coverings, and ceiling upholstery. Attempts are being made to make it applicable.

効率的であると言う利点がある。Polyethylene resin powder is commonly used as a hot melt adhesive, and recently, vinyl acetate/ethylene copolymer resins are being used. So-called dry lamination using this type of hot melt adhesive has the advantage that it does not require a drying process and is more efficient than wet lamination using an emulsion resin adhesive.

用される基材は厚手のカーペットやガラス繊維その他の
耐熱性の高いものに限られる。According to the conventional method, a hot melt adhesive is spread on the back side of a base material that is being conveyed in a large number of pins, and then conveyed as it is to a heating furnace equipped with a number of infrared lamps and surface heating burners, where it is heated and melted. This heating furnace is in an atmosphere at a high temperature above the melting point of the hot melt adhesive, and the hot melt adhesive cannot be used on base materials made of synthetic fibers or resins that have the same melting point as the resin composition. Furthermore, since dyes and synthetic fibers are adversely affected by the high temperature atmosphere of a heating furnace, the substrates to which the conventional method can be applied are limited to thick carpets, glass fibers, and other highly heat-resistant materials.
（発明の目的〕

る。(Objective of the Invention) Therefore, the present invention attempts to heat and laminate only the hot melt adhesive without adversely affecting the base material.

せることとした。In order to achieve such an object, the present invention does not bring about any particular change under normal conditions, but when placed close to a near-infrared lamp, it generates heat at an abnormally high temperature compared to plastic, and the heated plastic is heated by the near-infrared lamp. Based on new findings regarding substances that cause melting and near-infrared rays, a substance that absorbs the near-infrared rays and generates heat (hereinafter referred to as a photothermogenic substance) is kneaded and added to the resin composition of a hot melt adhesive, and the resulting material is prepared. The hot melt adhesive was irradiated with near-infrared rays from a close distance to generate heat in the photosensitive exothermic substance contained therein, and the hot melt adhesive was heated and melted via the photosensitive exothermic substance.

とする。That is, the present invention uses a laminating method in which a hot melt adhesive is spread on a base material and bonded by heating, in which the hot melt adhesive is made to contain a photosensitive heat generating substance, and the sprayed surface is irradiated with near infrared rays to release the photosensitive heat generating substance. It is characterized by generating heat, thereby heating and melting the hot melt adhesive to adhere it to the base material.

で使用することが出来る。Examples of the photogenerating substance include graphite, carbon black, and other charcoals, and the type thereof can be easily determined by near-infrared irradiation experiments, and is not an essential element of the present invention. However, a black or dark-colored substance does not necessarily correspond to a photosensitive exothermic substance, and therefore there is no need to add a photosensitive exothermic substance to make the hot melt adhesive black or dark-colored. That is,
The amount of the photosensitive exothermic substance added to the hot melt adhesive for carrying out the present invention is 0.5% of the composition resin of the hot melt adhesive.
The amount may be 1% by weight or less, and therefore, even when a carbon blank is used as a photosensitive exothermic material, the hot melt adhesive can be used without turning black.
ホットメルト接着材の着色を特に望まない場合には、着
色効果の少ない黒鉛を感光発熱物質に使用するとよい。If coloring of the hot melt adhesive is not particularly desired, graphite, which has little coloring effect, may be used as the photothermogenic substance.

とが推奨される。Next, to explain near-infrared rays applied to the present invention, infrared rays exist in an electrical frequency band of 10 Hz to 4 x 10 I+Hz, and have a wide wavelength range from 0.72 μ to 1000 μ between visible light and microwaves. has a band,
Depending on the wavelength band, infrared rays in the wavelength band from 0.72μ to 1.5μ are considered near infrared rays, infrared rays in the wavelength band from 1.5μ to 5.6μ are considered mid-infrared, and infrared rays in the wavelength band from 5.6μ to L000μ. Infrared rays are classified as far infrared rays, and various infrared irradiation lamps are commercially available according to these wavelengths. In the present invention, from 0.72μ to 1.5
It is recommended to use an infrared irradiation lamp that mainly emits near-infrared rays up to μ, particularly near-infrared rays with a wavelength of around 5μ (750 mμ), and to irradiate from a close distance within 10c11.

ラミネートが可能となる。As described above, according to the present invention, the hot-melt adhesive composition resin is heated and melted not directly by near-infrared rays, but indirectly by the photosensitive heat-generating substance that generates heat by near-infrared rays. That is, the near infrared rays themselves do not heat and melt the hot melt adhesive composition resin, nor do they heat and melt the base material. Therefore, the lamination of the present invention does not cause the base material to undergo thermal deterioration and discoloration, and therefore, even if the base material is made of the same plastic as the resin composition of the hot melt adhesive, it is possible to laminate with the hot melt adhesive.

According to the present invention, it can be used as a hot melt adhesive.
