Description
The technical field is as follows:
the invention relates to a front windshield installation strategy based on two-component polyurethane and one-component polyurethane adhesive, belonging to the technical field of passenger car manufacturing.
Background art:
at present, the front-grade glass is adhered and fixed on the front wall by using single-component polyurethane glass adhesive glue and matching with a hard cushion block and a fixed clamping plate, and the fixed clamping plate and the hard cushion block can be detached to finish the adhering operation after the adhesive glue is solidified for more than 8 hours. The single-component polyurethane glass adhesive is matched with the detachable hard cushion block and the fixed clamping plate, the time required by curing the adhesive is too long, the requirement of bonding the front gear at a fixed beat when the temperature is lower in winter cannot be met, the curing speed of the single-component polyurethane is slow in winter, the time required by fixing the clamping plate is possibly longer, and the bonding strength can be ensured.
Therefore, there is a need to improve the prior art to overcome the deficiencies of the prior art.
The invention content is as follows:
the invention provides a front windshield installation strategy based on two-component polyurethane and one-component polyurethane adhesive for solving the problems in the prior art, which can be suitable for being used in the environment with low temperature in winter and can quickly finish the adhesion and fixation of the front windshield.
The technical scheme adopted by the invention is as follows: a front windshield installation strategy based on two-component polyurethane and one-component polyurethane adhesive comprises the following steps:
the method comprises the following steps: cleaning a front stop seam, and then performing primary coating;
step two: cleaning the bonding part of the front glass, and then performing primary coating;
step three: punching two-component polyurethane glass bonding glue at four corners of a front stop seam allowance;
step four: single-component polyurethane adhesive is applied to the middle of four edges of the front stop seam allowance;
step five: placing the front stop glass on the front stop seam allowance and positioning;
step six: the lower edge of the front windshield is fixed through a fixing splint;
step seven: 1-2 hours later, the fixed splint is removed, the part of the soft elastic cushion block at the lower edge of the front windshield, which extends out of the length of the front windshield, is cut off, and the soft elastic cushion block is permanently reserved at the lower edge of the front windshield;
step eight: and cutting off the soft elastic cushion block, filling the joint sealant, and filling the joints 1-2 hours after the joint sealant is filled.
Furthermore, in the third step, the width of the colloid is 12-15mm, and the height is 12-15 mm.
Furthermore, in the fourth step, the width of the colloid is 12-15mm, and the height is 12-15 mm.
The invention has the following beneficial effects: in the front-end glass installation strategy based on the two-component polyurethane and the single-component polyurethane adhesive, the two-component polyurethane glass adhesive and the single-component polyurethane adhesive are simultaneously used, wherein, the four corners of the front stop seam are provided with two-component polyurethane glass adhesive, the other parts are provided with one-component polyurethane adhesive, the front stop glass is quickly fixed on the front stop seam by matching with the elastic cushion block and the fixed splint, and the fixed splint can be detached within 1-2 hours because the curing speed of the two-component polyurethane glass adhesive is not influenced by the temperature and the environment, meanwhile, the lower soft elastic cushion block can cut off the part extending out of the length of the glass, the soft elastic cushion block is permanently reserved on the lower edge of the front windshield, enough elastic support is provided in the whole life cycle of the front windshield, so that the problem that the quality of the front windshield is reduced due to the fact that the curing speed of the single-component polyurethane adhesive is low when the temperature is low in winter is avoided.
The specific implementation mode is as follows:
the invention relates to a front windshield installation strategy based on double-component polyurethane and single-component polyurethane adhesive, which comprises the following specific steps:
the method comprises the following steps: cleaning a front stop seam, and then performing primary coating;
step two: cleaning the bonding part of the front glass, and then performing primary coating;
step three: punching two-component polyurethane glass bonding glue at four corners of a front stop seam allowance, wherein the width of the glue is 12-15mm, and the height of the glue is 12-15 mm;
step four: the middle parts of four edges of the front stop seam are provided with single-component polyurethane adhesive, wherein the width of the adhesive is 12-15mm, and the height of the adhesive is 12-15 mm;
step five: placing the front stop glass on the front stop seam allowance and positioning;
step six: the lower edge of the front windshield is fixed through a fixing splint;
step seven: 1-2 hours later, the fixed splint is removed, the part of the soft elastic cushion block at the lower edge of the front windshield, which extends out of the length of the windshield, is cut off, and the soft elastic cushion block is permanently reserved at the lower edge of the front windshield;
step eight: and cutting off the soft elastic cushion block, filling the joint sealant, and filling the joints 1-2 hours after the joint sealant is filled.
The invention relates to a front-stop glass installation strategy based on double-component polyurethane and single-component polyurethane adhesive, which is characterized in that double-component polyurethane glass adhesive and single-component polyurethane adhesive are simultaneously used, wherein the double-component polyurethane glass adhesive is arranged at four corners of a front-stop seam allowance, the single-component polyurethane adhesive is arranged at other parts, the front-stop glass is quickly fixed on the front-stop seam allowance by matching with an elastic cushion block and a fixed splint, the fixed splint can be removed within 1-2 hours because the curing speed of the double-component polyurethane glass adhesive is not influenced by the temperature and the environment, meanwhile, the part extending out of the length of the glass can be cut off by a lower soft elastic cushion block, the soft elastic cushion block is permanently kept at the lower edge of the front-stop glass, enough elastic support is provided in the whole life cycle of the front-stop glass, and the problem that the curing speed of the front-stop glass is slow because of the single-component polyurethane adhesive in winter is avoided, and the production task is heavy, the beat is very fast, the fixed splint and the soft elastic cushion block can not be dismantled in advance to have sufficient curing time, and front-gear glass can sink to influence the product quality.
