Benefits of technology
Problems solved by technology
The existing adhesives for bonding PVC soft boards and sponges have the following obvious disadvantages: (1) Contains toxic organic volatile solvents, such as acetone, etc.
(2) The amount of glue applied is not easy to control, and the bond strength is unstable and low
Existing adhesives are generally applied by brushing or spraying, and both materials to be bonded must be coated, and the amount of glue applied and the film are difficult to control
If the amount of glue applied is insufficient, the thickness of the film is not enough to achieve the proper adhesion; if the amount of glue applied is too large and the film is too thick, good adhesion will not be produced, and the volatile solvent between the polymers will not easy to evaporate
(3), the material cost of existing adhesive is very high, is usually 4 to 5 times of the adhesive applied for in this patent
The above composite molding process is cumbersome and the manufacturing cost is high

Embodiment 1
[0037] An adhesive for bonding PVC soft board and sponge, which is composed of the following components in parts by weight:
[0038] 100 parts of paste PVC resin;
[0039] 70 parts of dioctyl phthalate;
[0040] 1.2 parts of dibasic lead phosphite;
[0041] 2.4 parts of tribasic lead sulfate;
[0042] Polyethylene wax 2.0 parts;
[0043] 1.0 part of carbon black;
[0044] Anti-aging agent 1.2 parts.
[0045] A construction method of the adhesive, comprising the steps:
[0046] (1) evenly coat the adhesive of claim 1 on a surface of the sponge;
[0047] (2) Heat the PVC soft board to the softening temperature, fit the heated PVC soft board to the sponge coated surface, and apply pressure to the bonding part until the PVC soft board cools.
[0048] refer to figure 1 , in the described step (1), the sponge 1 is placed horizontally between the rotating upper drum 2 and the lower drum 3, the lower drum 3 is partially immersed in the adhesive, and the lower surface of the sp...
Embodiment 2
[0050] An adhesive for bonding PVC soft board and sponge, which is composed of the following components in parts by weight:
[0051] 100 parts of paste PVC resin;
[0052] 72 parts of dioctyl phthalate;
[0053] 1.5 parts of dibasic lead phosphite;
[0054] 3.4 parts of tribasic lead sulfate;
[0055] Polyethylene wax 1.2 parts;
[0056] 1.0 part of carbon black;

Abstract
The invention relates to an adhesive for bonding PVC soft boards to sponges, which comprises the following components in parts by weight: 100 parts of pasty PVC resin, 65 to 75 parts of dioctyl phthalate, 1.0 to 2.0 parts of dibasic lead phosphite, 2.0 to 5.0 parts of tribasic lead sulphate, 1.0 to 2.0 parts of polyethylene wax, and 0.8 to 1.5 parts of carbon black. A construction method of the adhesive comprises the following steps: (1) uniformly coating the surface of a sponge with the adhesive in a patent claim 1; and (2) heating a PVC soft board to a softening temperature, pasting the heated PVC soft board to the adhesive-coated surface of the sponge and applying pressure to pasted parts till the PVC soft board is cooled. The adhesive has the advantages of no organic volatile matter, easy control over the quantity of adhesive coating, low cost and simple molding process.
Description
(1) Technical field [0001] The invention relates to an adhesive used for bonding PVC soft boards and sponges and a construction method thereof. (2) Background technology [0002] At present, in the fiercely competitive international automobile market, the comprehensive "cost-effectiveness" of the same grade models in terms of conventional performance is getting closer and closer and has reached a high level. Therefore, improving the level of vehicle noise control has become a new competitive focus and technology. Direction of development. In this context, the NVH (Noise / Vibration / Harshness) performance of a vehicle is gradually evolving into an important design indicator, and it is also one of the vehicle performance indicators that users care about. The level of vehicle noise control will definitely become one of the indispensable and important factors that determine the success of vehicle development, and the noise in the engine compartment is an important part of the ent...
