The present invention relates to an adhesive composition for vehicle interior materials. For details, see particle density 0.05-0.5
g/cm 3 , 3 to 100 parts by weight of hollow glass particles with an average particle diameter of 10 to 100 μ, polymer latex (solid content) 100
The present invention relates to an adhesive composition for vehicle interior materials, which mainly contains 300 parts by weight or less of thermoplastic resin powder. Traditionally, needle punch carpets, nonwoven fabrics,
Tuffed carpet etc. are used. Interior materials used in such applications are required to have flame retardant properties, sound insulation properties, heat insulation properties, and moldability. Furthermore, although weight reduction is required, it must not detract from the sense of luxury. Conventionally, adhesives containing large amounts of aluminum hydroxide, phosphorus-based or antimony-based flame retardants have been used for interior materials for vehicles to impart flame retardancy. However, aluminum hydroxide needs to be blended in a large amount, and phosphorus-based and antimony-based flame retardants are toxic and undesirable. Additionally, felt or sheets are placed between the floor and carpet to improve sound insulation and heat insulation. However, such a method increases the number of steps and increases the weight, so it is not preferable especially for vehicles (airplanes, automobiles, etc.) that require energy saving through weight reduction. As a way to improve the weight reduction of carpets, reducing the amount of fibers such as pile is being considered.
This is undesirable because it detracts from the luxurious feel of the carpet. In addition, consideration has been given to reducing the weight of the adhesive by foaming the adhesive, but the foam may collapse during processing or the rigidity of the carpet may deteriorate, resulting in poor dimensional stability. The present inventors have completed the present invention as a result of intensive research to improve the above-mentioned drawbacks. That is, the present invention has a particle density of 0.05 to 0.5 g/
cm 3 , 3 to 100 hollow glass particles with an average particle size of 10 to 100μ
The present invention provides an adhesive composition for vehicle interior materials, characterized in that it mainly contains 100 parts by weight of polymer latex (solid content) and 300 parts by weight or less of thermoplastic resin powder. The polymer latexes used in the present invention include natural rubber latex, SBR latex, self-crosslinking SBR latex, NBR latex, self-crosslinking NBR latex, polychloroprene latex, ethylene-vinyl acetate copolymer latex, and vinyl chloride polymer. Latex, polyvinyl acetate emulsion, etc. Self-crosslinking SBR latex is preferably used from the viewpoint of compoundability, adhesive strength, stability, etc. Further, the glass particles used in the present invention include those commonly used as glasses, such as soda lime glass, potash glass, quartz glass, and hard glass. However, the particles must be hollow particles with a true density of 0.05 to 0.5 g/cm 3 . When the particle density is less than 0.05 g/cm 3 , it is difficult to use because it is too light and scatters in the air during compounding. For particles exceeding 0.5g/ cm3 ,
The weight reduction effect is small. The amount of glass particles added is
The amount is 3 to 100 parts by weight per 100 parts by weight of polymer latex (solid content) which is the main component of the adhesive composition.
If the amount is less than 3 parts by weight, no effects such as weight reduction, flame retardancy, sound insulation, and heat insulation will be observed. Furthermore, if more than 100 parts by weight is added, the adhesive strength and stability during compounding will be poor. The average particle diameter of the hollow glass particles is 10 to 100 microns. Particles smaller than 10 microns will be difficult to incorporate into polymer latex, and particles larger than 100 microns will reduce adhesive strength. The thermoplastic resin powder used in the present invention includes polyethylene resin, ethylene-vinyl acetate copolymer resin, polypropylene resin, 1,2-polybutadiene resin, polyvinyl chloride resin, polyvinylidene chloride resin, polyacrylic acid ester resin, Polymethacrylate resin, polyvinyl acetate resin,
Examples include powders of thermoplastic polyester resins, polyamide resins, and the like. In particular, polyvinyl chloride resin is preferably used because it not only has the effect of improving the moldability of the carpet but also improves flame retardancy. These are used in an amount of 300 parts by weight or less per 100 parts by weight of polymer latex (solid content). If it exceeds 300 parts by weight, the adhesive strength will be poor. The adhesive composition of the present invention can be mixed with commonly used additives. Vehicle interior materials to which the adhesive composition of the present invention can be used include all woven and nonwoven fabrics such as tufted carpets, knitted carpets, and hook carpets. There are also products that have been laminated to the back side with backing materials such as woven fabric, jute woven fabric, synthetic non-woven fabric, and tortoiseshell gauze. The present invention will be described below with reference to Examples, but the present invention is not limited by the Examples. Example 1 A dispersion was prepared in a beaker equipped with a stirrer in the following proportions. Part by weight Self-crosslinking SBR latex 100 (solid content) Anti-aging agent 1 Dispersant Add filler* and vinyl chloride resin powder to the dispersion of 0.5 or more as shown in Table 1, and add antifoaming agent and polyacrylic acid. Add soda to increase viscosity
The adhesive composition was adjusted to 10,000 centipoise. This adhesive composition was applied to the back side of a nonwoven matte gray fabric whose fiber material was polypropylene, with an apparent surface area of 500 cm 3 /m 2
The coating was applied uniformly and dried to obtain a vehicle interior material. This interior material is used to test the flammability of automobiles.
Evaluated according to FMVSS No.302. In addition, the heat insulation properties were evaluated by placing a boiling beaker on top of the pile of interior material and measuring the time it took for the temperature on the back side to rise from 35°C to 50°C. In addition, the interior material was bent at a 90 degree angle at 80℃, molded for 1 hour, released from the mold, and left at 25℃.
The moldability was evaluated by measuring the angle that was larger than the 90 degree angle.
