- window glazing that does not open and close the vehicle, such as the windshield and rear glass of automobiles, is a method of attaching the glass directly to the automobile body using a sealing material (also called an adhesive) that has high adhesive strength.
- Lazin is often attached to the car body by a method called.
- the sealing material obtained by the present invention can satisfy the following conditions. (1) The sealing material itself must have high mechanical strength so as not to be damaged. And specifically, having a breaking strength of 3 MPa or more;
- the sealing material must have a certain degree of hardness and have rubber elasticity so that vibrations and shocks are not transmitted to the glass.Specifically, a modulus at 100% extension of 1 MPa or more and a modulus of 200% or more A rubber elastic body having elongation at break;
- the sealing material should be quickly cured, specifically, the surface should be cured in about 10 to 45 minutes after being left in the air at room temperature;
- Hexane was distilled off under reduced pressure, and the atmosphere was replaced with nitrogen.
- a platinum vinyl catalyst (3% by weight of xylene solution in terms of platinum) of 11 ⁇ 1 was added, and 6 V o of oxygen was added to the gas phase of the reactor.
- Nitrogen containing 1% was charged at normal pressure.
- 0.5 g of 2,6-di-tert-butyl-p-cresol as an antioxidant was mixed with 55 / zl of sulfur (0.1% by weight toluene solution).
- 2.5 g of DMS was slowly added dropwise. The mixed solution was reacted at 90 ° C., and the reaction was observed over time.
- a curable resin composition was obtained by adding the compounding agents shown in Table 1. The operation was performed using a planetary mixer. The calcium carbonate and force pump rack were heated and dried, and then the oligomer obtained in the synthesis example and other compounding agents were added and kneaded. Comparative example A curable resin composition was obtained by adding the same compounding agents as in Example 1 shown in Table 1, except that the reactive silicon group-containing polyether oligomer obtained in Comparative Synthesis Example 1 was used. . Using a planetary mixer, the calcium carbonate and the carbon black were dried by heating, and then the oligomer obtained in Comparative Synthesis Example and other compounding agents were added and kneaded. table 1
- Note 1 indicates an oxypropylene polymer having an aryloxy group terminal and an average molecular weight of 100,000. Comparative Examples 2, 3
- Comparative Example 2 was U-418 manufactured by Esse X, and Comparative Example 3 was a repair polyurethane made by 3M Company).
- the properties of the curable resin composition or the physical properties of the cured product were measured as follows.
- the obtained curable resin composition was filled in a container having an open top, cured in an atmosphere of 23 ° C. and 60% RH, and the time required for the disappearance of the stringing phenomenon on the surface of the composition (peeling time) was measured. .
- the curable resin composition was stretched on a polyethylene film to a thickness of 3 mm and left at 23 in a 60% RH atmosphere for a certain period of time. Create a No. 3 dumbbell according to JISK 6301 and measure the tensile properties (modulus at 100% elongation (Ml 00), breaking strength (TB), elongation at break (EB)) at a tensile speed of 20 OmmZ. did.
- the curable resin composition was filled in a container having an open top, left for a certain period of time in an atmosphere of 23 ° C. and 60% RH, and then the cured layer was taken out.
- the thickness of the central portion was measured as the curing depth. The greater the thickness, the more excellent the deep curing property.
- Example 1 and Comparative Example 1 used curable resin compositions that differed only in the rate of introduction of the reactive silicon group into the resin.
- Example 1 was different from Comparative Example 1 in tensile properties. And deep-set curability increases, adhesive strength increases significantly, and reaches twice the strength.
- Example 2 is obtained by adding a processing aid to Example 1, and the physical properties are improved as compared with Example 1.
- Examples 1 and 2 are comparable to Comparative Examples 2 and 3, which are conventional urethane sealing materials, and have better physical properties in some aspects.
- Table 2 it can be seen that the cured product of the curable resin composition of the present invention has a sufficient balance of breaking strength and elongation at break (rubber elasticity) as a direct-glazing sealing material used in vehicles. I understood. It was also found that the adhesive strength was high and the curing speed was sufficiently high as a sealing material for direct glazing. Industrial applicability
- the reactive silicon group is present only at the terminal of the molecular chain, and the rate of introduction of the reactive gay group into the terminal of the molecular chain is 85% or more according to 1 H-NMR analysis.
- Glass component by direct glazing method because it has a good balance of strength, elongation properties, etc., and has sufficient breaking strength, elongation, curing speed, and excellent adhesive strength because it uses a polyether oligomer containing a functional silicon group as a curing component. It is suitable for mounting.
