A kind of production method of cardboard
The present invention is dividing an application of patent of invention " a kind of production equipment and production method ", the applying date of original application is on May 6th, 2012, the application number of original application is 2012101404982, and the invention and created name of original application is " a kind of production equipment and production method ".
Technical field
The present invention relates to a kind of production equipment and production method, relate in particular to a kind of production equipment and production method that dual-component polyurethane foamed glue is cardboard interlayer of take, belong to production technical field.
Background technology
Dual-component polyurethane foamed glue claims again it is dual-component polyurethane fluid sealant, is commonly called as AB material, black and white material, two component sealing gum, and it has the several functions such as caulking and sealing, bonding, antiseepage.Dual-component polyurethane is that to take polyethers, polyisocyanates be primary raw material, a kind of normal-temperature reaction curing type elaxtic seal that adds again curing agent, filler and multiple auxiliary agent to form, the manufacturers such as product density, soft durometer and foamed time can adjust by the specific requirement of user's technique.
Dual-component polyurethane foamed glue belongs to two-part reaction-curable, A, B two components, consists of.B group is normal claims that white material is generally light yellow thick base polyurethane prepolymer for use as, A group is normal claims that black material is black colloid or the liquid that the mixed dehydrations such as curing agent and auxiliary agent form, by instructions for use, can there be non-sagging type and gravity flow flat pattern, dual-component polyurethane foamed glue has following characteristics: 1, modulus is moderate, elasticity is high, percentage elongation is large, and ageing-resistant, low temperature resistant, water-fast, acid-alkali-corrosive-resisting, fatigue performance are good; 2, very strong cohesive force; 3, solvent-free, containing tar, pitch, pollution-free, not nontoxic; 4, construction technology is simple, during construction only need by A, B two components to scale mixing and stirring can use; 5, curing rate is very fast; 6, can require to make shades of colour and different class products according to user; 7, adjust the ratio of two kinds of components, also can make adhesive or waterproof material and use.
The cardboard of known technology claims again paperboard.The ground paper page being processed into by various paper pulp, fiber is interweaved and forms.The difference of cardboard and paper is distinguished with quantitative and thickness conventionally, generally will quantitatively surpass 200g/m
2, thickness is greater than the cardboard that is called of 0.5mm, the cardboard of indication of the present invention is packaging board, as corrugated board, honeycomb cardboard.
Current known production technology, no matter be corrugated board or honeycomb cardboard, exist the equipment of streamline huge, every production line investment is more than 5,000,000 to 1,000 ten thousand, the defects such as finished product cardboard water-resistance is poor, before the present invention does not make, without having, a kind ofly take production equipment and the production method that dual-component polyurethane foamed glue is cardboard interlayer and use, patent searching document is open without the new technical scheme of this technology.
Summary of the invention
In order to overcome existing nothing, there are a kind of take production equipment that dual-component polyurethane foamed glue is cardboard interlayer and the deficiency of production method, the object of the invention is for a kind of production equipment and production method that dual-component polyurethane foamed glue is cardboard interlayer of take is provided, the device miniaturization of this production equipment and production method, production technology is convenient, finished product cardboard water-resistance is strong, reaches and reduces the object that cost of investment improves product usefulness and improves the performance of enterprises.
The present invention solves the technical scheme that its technical problem takes: by facial tissue bucket, base stock cylinder, facial tissue, base stock, upper colored roller, lower colored roller, upper glue spreader, lower glue spreader, upper groove, lower groove, polyurethane foams A component, polyurethane foams B component, front upper deflector roll, front lower guide roll, upper heating plate, lower heating plate, rear upper deflector roll, rear lower guide roll, upper knife plate, lower knife plate, finished product cardboard forms, it is characterized in that in groove, there is polyurethane foams A component, there is upper glue spreader the top of upper groove, upper glue spreader contacts with polyurethane foams A component, there is upper colored roller the top of upper glue spreader, upper colored roller be surface have protrude decorative pattern beaming roller, the lower surface of upper colored roller is contrary with the contact of the upper surface of upper glue spreader and direction of rotation, in lower groove, there is polyurethane foams B component, above lower groove, there is lower glue spreader, lower glue spreader contacts with polyurethane foams B component, the right side of lower glue spreader contact with the left side of lower colored roller and direction of rotation contrary, lower colored roller be surface have protrude decorative pattern beaming roller, while producing corrugated board, the surface of upper flower roller and lower colored roller is vertical bar shaped decorative pattern, while producing honeycomb cardboard, the surface of upper flower roller and lower colored roller is reticulate pattern shape decorative pattern, the size of upper colored roller and lower colored roller is identical and decorative pattern is identical, the direction of rotation of upper colored roller and lower colored roller is contrary, during equipment operation, upper colored roller and upper glue spreader and front upper deflector roll and rear upper deflector roll rotate simultaneously and pull the facial tissue bucket passive movement of facial tissue, polyurethane foams A component in the upper groove of upper glue spreader contact, polyurethane foams A component is the protrusion patterned surface to upper colored roller by the surperficial roller coating of upper glue spreader, in the contact movement of upper colored roller and facial tissue, upper colored roller is the lower surface to facial tissue by the roller coating of polyurethane foams A component, same roller and lower glue spreader and front lower guide roll and the rear lower guide roll spent at present of device start rotates simultaneously and pulls the base stock bucket passive movement of base stock, polyurethane foams B component in the lower groove of lower glue spreader contact, polyurethane foams B component is the protrusion patterned surface to lower colored roller by the surperficial roller coating of lower glue spreader, in the contact movement of lower colored roller and base stock, lower colored roller is the upper surface to base stock by the roller coating of polyurethane foams B component, facial tissue by front upper deflector roll time base stock pass through lower guide roll, facial tissue contacts with base stock, it is bonding after the polyurethane foams B component of the polyurethane foams A component of the lower surface of facial tissue and the upper surface of base stock contacts, polyurethane foams A component and polyurethane foams B component reaction post-foaming expand, upper heating plate and lower heating plate carry out heating cure and setting to the facial tissue after expanding and the adherend of base stock, cardboard after setting length according to actual needs obtain finished product cardboard after shearing via upper knife plate and lower knife plate, reach and reduce the object that cost of investment improves product usefulness and improves the performance of enterprises.
The equipment that the invention has the beneficial effects as follows is simple, and production technology is convenient, and finished product cardboard water-resistance is strong, reaches and reduces the object that cost of investment improves product usefulness and improves the performance of enterprises, and practicality is large.
