Description
Technical Field
The invention belongs to the technical field of automobile sealing strip flocking, and particularly relates to an online hot-laminating process for a flocking strip of an automobile EPDM glass guide groove sealing strip.
Background
The traditional sealing strip is made of EPDM material, and the name of the traditional Chinese is ethylene propylene diene monomer. Ethylene propylene diene rubber is a terpolymer of ethylene, propylene and a non-conjugated diene. The primary properties of EPDM are its excellent resistance to oxidation, ozone and corrosion. Since ethylene-propylene-diene monomer rubber belongs to the Polyolefin (PO) family, it has excellent vulcanization characteristics. Among all rubbers, EPDM has the lowest specific gravity, and can absorb a large amount of filler and oil without much influence on the characteristics, so that a rubber compound can be produced at low cost.
The main polymer chain of epdm is fully saturated, which makes epdm resistant to heat, light, oxygen, and especially ozone. Ethylene propylene diene is essentially non-polar, resistant to polar solutions and chemicals, low in water absorption and good in insulating property.
Therefore, the composite material can be widely applied to the fields of automobile parts, waterproof materials for buildings, wire and cable sheaths, heat-resistant rubber tubes, adhesive tapes, automobile sealing parts and the like.
However, when the automobile sealing strips such as the glass guide grooves and the water cutting strips are produced, flocking or flocking needs to be carried out on the contact surface of the sealing strips and the glass, so that the friction force and the noise of the lifting of the glass are reduced, and the sealing performance and the comfort level of the automobile are improved. The prior art adopts the on-line electrostatic flocking or off-line electrostatic flocking process for production. There are two main types:
1. the online electrostatic flocking has the defects that the existing sealing element factory adopts oily flocking glue for online electrostatic flocking, and no water-based glue can meet the requirement in the existing market, so that the construction site is more in toxic and harmful substances and is not environment-friendly, the existing flocking process is also complex, and particularly, the partial section is curved, the phenomena of glue leakage and the like can be caused frequently, and the caused scrapping is large.
2. The PE belt is attached and online electrostatic flocking is carried out, the defects that the PE belt can only be attached to the bottom edge and cannot be attached to the lip edge, the two process combination modes are needed for the bottom edge and the lip edge, and meanwhile, the PE belt is good in wear-resisting effect, not high in temperature resistance and poor in sealing effect, and easily causes abnormal sound of glass lifting.
Therefore, a sealing strip flocking process which is more environment-friendly and simple and convenient to produce is needed, the cost is reduced, and the flocking effect is improved.

Meanwhile, compared with the EPDM sealing strip produced by the traditional electrostatic flocking, the EPDM sealing strip produced by the hot laminating process has the advantages that the flocking effect is better, fluff coverage is more uniform, the possibility of increasing the friction force of the glass due to nonuniform flocking is reduced in the using process, and the noise of the automobile glass in the lifting process is reduced. The content of harmful VOC and harmful irritant gas in the EPDM sealing strip in the automobile is reduced in the using process.
The process of the embodiment comprises the following steps:
step one, molding, namely extruding and molding an EPDM sealing strip raw material through a high-temperature neck ring die to obtain an EPDM sealing strip;
vulcanizing or curing, namely vulcanizing or curing the EPDM sealing strip obtained by extrusion molding;
and step three, fitting, namely performing hot fitting on the flocked belt and the vulcanized or cured EPDM sealing strip.
And the first step is to heat and melt the EPDM sealing strip rubber material and then extrude and mold the rubber material through a neck ring mold to obtain the soft EPDM sealing strip with the shape.
And the second step is to obtain the required EPDM sealing strip with hardness and resilience after the soft EPDM sealing strip obtained by extrusion molding is heated and vulcanized or heated and cured, wherein the vulcanization is to improve the hardness and the elasticity of the soft EPDM sealing strip by heating and vulcanizing, the heating temperature of the vulcanization is 120-350 ℃, 250 ℃ is preferred in the embodiment, linear macromolecules in the soft EPDM sealing strip are converted into a three-dimensional reticular structure at the temperature of 250 ℃ in the soft EPDM sealing strip, so that the soft EPDM sealing strip is gradually hardened, and meanwhile, the elasticity is gradually increased, and finally the EPDM sealing strip with hardness and resilience is obtained. The curing is specifically to improve the hardness and elasticity of the soft EPDM sealing strip through heating and curing.
The heating temperature of the curing of this embodiment is 120 ~ 350 ℃, 250 ℃ is preferred in this embodiment, and in the curing process, the linear macromolecule in soft EPDM sealing strip changes into three-dimensional network structure for soft EPDM sealing strip hardens gradually, and elasticity also rises gradually simultaneously, finally obtains the EPDM sealing strip that has hardness and resilience. The curing is specifically to improve the hardness and elasticity of the soft EPDM sealing strip through heating and curing.
The third step of this embodiment specifically is to carry out the hot melt laminating with the flocking belt on the EPDM sealing strip surface that has hardness and resilience with the vulcanization waste heat after the vulcanization or the solidification waste heat after the solidification, obtain the EPDM sealing strip that has the flocking face, the hot melt laminating specifically is to pull and press the flocking belt on the surface of EPDM sealing strip, the flocking belt is heated by the vulcanization waste heat after the EPDM sealing strip vulcanization or is heated by the solidification waste heat after the EPDM sealing strip solidification, the gum of flocking belt is heated the melting and adheres on the surface of EPDM sealing strip, the temperature that the flocking belt carries out the hot melt laminating with the vulcanization waste heat after the vulcanization is 80 ~ 290 ℃, the temperature that the flocking belt carries out the hot melt laminating with the solidification waste heat after the solidification is 80 ~ 290 ℃.
The laminating speed of the hot laminating process of this embodiment is 1m/min ~ 35m/min, when laminating speed was too fast, the gum of flocking area had not combined evenly just to accomplish the laminating with the EPDM sealing strip completely yet, and the laminating effect is not good, when laminating speed was crossed lowly, the temperature that vulcanizes or the temperature of not laminating the EPDM sealing strip after the solidification can be because laminating speed is too slow and temperature reduction when the laminating for the gum of flocking area can not be better carry out the hot melt and cause flocking area and combine inseparable, can not reach the effect.
