Footwear calendering type rubber hold-down calendering glue decorative pattern maintenance method
Technical field
The present invention relates to a kind of elastomeric material preparation field, especially a kind of footwear calendering type rubber hold-down calendering glue decorative pattern maintenance method.
Background technology
Current foxing glue decorative pattern aborning easy produced problem has: foxing vulcanization of rubber speed is slow, and in sulfuration type-approval process, heat effect produces decorative pattern distortion; Sizing material plasticity is unstable, and elastomeric compound hardness is low, and in bonding processes, surface detail is crushed out of shape, and destroys presentation quality image.
Summary of the invention
The object of the invention is: a kind of foxing glue decorative pattern line maintenance method is provided, its technique effect is that removing from mould film one surface detail is after the pressure effect of each operation of rubber shoe molding, product film face phenomenon decorative pattern is indeformable, improves product appearance quality, to overcome the deficiencies in the prior art.
The present invention is achieved in that footwear calendering type rubber hold-down calendering glue decorative pattern maintenance method, after sizing material is rolled removing from mould, obtains foxing; Left in by foxing on the PP plate of band Baltimore groove, the Baltimore groove on PP plate is corresponding with foxing size and shape, and foxing deposits more than 24 hours on PP plate; Foxing after placing is carried out pressing, surface is used to scribble the bipeltate air bag of the organic silicon rubber coating that thickness is 2-3mm as pressure conduction body, in bonding processes, bipeltate air bag deforms because of stressed, make the pressing of foxing sheet rubber be cemented in the stickup position of footwear, not only ensure that bonding is firm but also do not make foxing decorative pattern produce distortion.
The pressure of pressing working procedure is 0.39-0.43MPa, pressing time 3.2-3.5 second.
When preparing the sizing material of foxing, controlling the plasticity of broken-down rubber is 0.40-0.45, and the plasticity of elastomeric compound is 0.40-0.45, the sulfuration starting point of elastomeric compound be 2 points 10 seconds-2 points 50 seconds.
In order to verify effect of the present invention further, carry out following experiment:
According to experiment results proved, use the PP plate of band band Baltimore groove to deposit foxing adhesive tape, can guarantee that foxing not to stress distortion in line face altogether, be easy to again operative employee and pick sheet operation, significant.
Owing to have employed technique scheme, compared with prior art, effective effect of the present invention is: shoe rubber line remains respond well, rubber overshoes bar removing from mould film one surface detail is after the pressure effect of each operation of rubber shoe molding, product film face phenomenon decorative pattern is indeformable, improve product appearance quality.The present invention is simple, with low cost, and result of use is good.
Detailed description of the invention
Embodiments of the invention 1: footwear calendering type rubber hold-down calendering glue decorative pattern maintenance method, when preparing the sizing material of foxing, controlling the plasticity of broken-down rubber is 0.40, and the plasticity of elastomeric compound is 0.45, the sulfuration starting point of elastomeric compound be 2 points 30 seconds; After sizing material is rolled removing from mould, obtain foxing; Left in by foxing on the PP plate of band Baltimore groove, the Baltimore groove on PP plate is corresponding with foxing size and shape, and foxing deposits more than 24 hours on PP plate; Foxing after placing is carried out pressing, and the pressure of pressing working procedure is 0.39MPa, pressing time 3.5 seconds; Surface is used to scribble the bipeltate air bag of the organic silicon rubber coating that thickness is 2mm as pressure conduction body, in bonding processes, bipeltate air bag deforms because of stressed, make the pressing of foxing sheet rubber be cemented in the stickup position of footwear, not only ensure that bonding is firm but also do not make foxing decorative pattern produce distortion.
Embodiments of the invention 2: footwear calendering type rubber hold-down calendering glue decorative pattern maintenance method, when preparing the sizing material of foxing, controlling the plasticity of broken-down rubber is 0.45, and the plasticity of elastomeric compound is 0.45, the sulfuration starting point of elastomeric compound be 2 points 10 seconds; After sizing material is rolled removing from mould, obtain foxing; Left in by foxing on the PP plate of band Baltimore groove, the Baltimore groove on PP plate is corresponding with foxing size and shape, and foxing deposits more than 24 hours on PP plate; Foxing after placing is carried out pressing, and the pressure of pressing working procedure is 0.43MPa, pressing time 3.2 seconds; Surface is used to scribble the bipeltate air bag of the organic silicon rubber coating that thickness is 2mm as pressure conduction body, in bonding processes, bipeltate air bag deforms because of stressed, make the pressing of foxing sheet rubber be cemented in the stickup position of footwear, not only ensure that bonding is firm but also do not make foxing decorative pattern produce distortion.
Embodiments of the invention 3: footwear calendering type rubber hold-down calendering glue decorative pattern maintenance method, when preparing the sizing material of foxing, controlling the plasticity of broken-down rubber is 0.45, and the plasticity of elastomeric compound is 0.40, the sulfuration starting point of elastomeric compound be 2 points 50 seconds; After sizing material is rolled removing from mould, obtain foxing; Left in by foxing on the PP plate of band Baltimore groove, the Baltimore groove on PP plate is corresponding with foxing size and shape, and foxing deposits more than 24 hours on PP plate; Foxing after placing is carried out pressing, and the pressure of pressing working procedure is 0.40MPa, pressing time 3.3 seconds; Surface is used to scribble the bipeltate air bag of the organic silicon rubber coating that thickness is 2mm as pressure conduction body, in bonding processes, bipeltate air bag deforms because of stressed, make the pressing of foxing sheet rubber be cemented in the stickup position of footwear, not only ensure that bonding is firm but also do not make foxing decorative pattern produce distortion.
