Non-limiting examples under M. The invention is further described by M. Example: In the examples presented in Tables 1-5 below, NMP-based solvent adhesives are formulated. The required VOC content is determined by the choice of two solvents. Using &quot; SCAQMD 316A, experiment with solvents for solvent-based adhesives • Determine VOC constants. The estimated VOC of each solvent-based adhesive is then determined by using the following formula: (VOC constant of solvent 1 x solvent 1 is based on the total amount of solvent in the adhesive ! "+ (VOC constant of solvent 2 X solvent 2 is based on the total amount of solvent in the adhesive! 〇 + Similar calculation of additional solvents = estimated VOC content of the adhesive. Once the VOC constant required for this is determined, formulate Low VOC solvent-based adhesive and test the VOC content using SCAQMD 316A. The viscosity of the solvent adhesive is optimized by adding a shaker. The strength of the blank and the curing time are adjusted by the solvent ratio while maintaining the required VOC Content and viscosity change. In the first example (Examples 1-4), the amount of NMP and dimethyl adipate (DMA) used was changed. The formulas in the first example were tested for VOC content, curing time, and blank.

V. Description of the invention (22) Examples 33 to 43 are described as having 0.54 to 0.97. DMA / NMP ratio and M are less than 10% by weight of the total formulation. Solvent-based solvents with MEK (2-butanone) as a small amount of ingredients, with adhesives based on commercial solvents (with 450 g / L or higher) V0C contains children) low V0C content, and gauges such as these commercial solvent-based adhesives. In addition, Example 38 describes a solvent-based solvent having a DMA / NMP ratio of less than 0.55 and a weight of less than 8 weights of the total formulation. The solvent has MEK (2-butane) as a small amount of solvent, and has a VOC content of 201 g / liter. And gauges such as conventional solvent-based adhesives. Μ The example in Table 5 below describes how substituted naphthalenes with 11 to 14 carbon atoms and / or g-substituted benzenes with 10 to 14 carbon atoms can be substituted with NM in solvent-based binders and Generates a low VOC value according to SCAQMD 316A (eg, as low as 73g / l), and meets the physical property test of solvent-based adhesives. Examples of ME K having a weight percentage of δ are less desirable flash points than other examples having a higher M I using ketones. The addition of rhenium tends to reduce the time required for the strength of the billet, but increases the V0C content. The specificity of dicarboxylic acid and methanol (DBE-6) is substituted with other such esters. The methyl naphthalene used for the experiment was> 95 weight percent pure cSS-150 was Sure Sol®, which was a Cio isomer of 98 weight percent benzene and SS-150ND was similar to SS-150, but depleted of naphthalene. SS-150 and 150ND are obtained from petroleum distillate fractions from Koch Specialty Chemicals, Corpus Christi, Texas. -24- This paper size applies the Chinese National Standard (CNS) Λ4 specification (210X 297) while G9S00 ^ (Please read the precautions on the back before filling out this page)-Installation, Ye V.
