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

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 highly competitive international automobile market, the comprehensive "price ratio" of vehicles of the same grade in terms of conventional performance is getting closer and has reached a higher level. Therefore, improving the level of vehicle noise control has become a new focus of competition and technology. Direction of development. In this context, the NVH (Noise / Vibration / Harshness) performance of vehicles 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 car noise control will definitely become one of the indispensable and important factors that determine the success of model development, and the noise in the engine compartment is an important part of the entire NVH system. I...
