Abstract
The utility model relates to a plastic honeycomb. The main technique feature is that the plastic honeycomb is made by the plastic pipe tightly arranged. The outer wall space is the honeycomb which is compounded into integration by the bonding material. The structural feature of the utility model plastic honeycomb can make the making method simple and the honeycomb bore diameter and the wall thickness of the honeycomb material can be changed discretionarily. It only needs to arrange the plastic pipe with different pipe diameter and wall thickness in the mould and then compound them together. A suite mould can adapt to produce various honeycomb materials with different honeycomb bore diameter and wall thickness and the plastic pipe (honeycomb bore) material can be selected discretionarily. The plastic honeycomb is provided with simple producing process and low equipment investment.
Description
Technical field
The utility model relates to plastic honeycomb.
Background technology
The plastic honeycomb material has good water-resistant stability, medium corrosion resistance, buffering shock resistance and low thermal conductivity, is widely used in industries such as car and boat, aviation, building, building materials.Traditional plastic honeycomb manufacture craft mainly is to utilize the mould once injection moulding, is cut to needed size then.This explained hereafter efficient is than higher, the plastic honeycomb cellular unit of producing has good bonding strength, but the specification of honeycomb aperture and wall thickness and material are subjected to the restriction of equipment and mold, do not have versatility, thereby need bigger equipment, mould to invest the product of producing corresponding specification.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of plastic honeycomb, and preparation method is simple, can produce the cellular material of various honeycombs aperture and wall thickness easily.
Plastic honeycomb of the present utility model, the major technique characteristics are closely to be arranged by plastic pipe, compound by bonding material between outer wall is the honeycomb ceramics of one.
Making the method for plastic honeycomb material, is plastic pipe to be placed closely to arrange in the mould by bonding material is compound be one, and vertically cutting obtains being fit to the plastic honeycomb material of length then.
The design feature of the utility model plastic honeycomb, can make preparation method simple, and the honeycomb aperture and the wall thickness of cellular material change arbitrarily, only need the plastic pipe of different tube diameters and wall thickness is placed in the mould, then they are combined with each other, a mold just can adapt to the cellular material of producing various honeycombs aperture and wall thickness obviously, and the material of plastic pipe (honeycomb hole) can be chosen arbitrarily.
Compound employing bonding material between plastic pipe, bonding material can be a solvent-borne type colloidal sol, also can be adhesive, foamed glue, thermosol.Following division:
1, solvent-borne type colloidal sol welds method:
This method is to utilize the dissolubility of plastics and its degree of crystallinity, and the plastics that commute is molten, degree of crystallinity is lower are more suitable.The solvent-borne type colloidal sol of selecting for use requires and by sticking material close solubility coefficient is arranged, and can adopt the solvent of known one-component, also can be the composite mixed sols that forms with sticking material of quilt and solvent, and its solid content is advisable between 20～60%.
Operating process is:
Plastic pipe is carried out cleaning treatment, mainly is the anti-stick material of removing dirt and pipe outer surface.Plastic tube outer wall coating colloidal sol after the processing makes a part of solvent evaporates through nature or manual type, puts into mould and compresses arrangement successively.Also can earlier plastic pipe be put into mould spray glue or brush coating, slough partial solvent, compress arrangement successively with hot blast.Compound is the honeycomb ceramics further nature or the heated-air drying of one.In order to increase the adhesive strength between each cellular unit, can suitably pressurize and make plastic pipe deformation, increase the bond area between the cellular unit.After solidifying fully, cut the cellular material that obtains required size.These cellular materials are spliced to form the larger area honeycomb article again.
2, structure glue composite algorithm:
This method is to utilize adhesive or foamed adhesive to be one with compound between plastic pipe.Consider from economical with materials, plastic tube outer wall can be only at bonding position gluing.Adhesive commonly used has polyurethane, melamine, rubber modified resin etc.Foamed adhesive can be selected well-known components such as polyurethane for use, in bonding, with the triangular open space filled plastics foam between the plastic pipe (being cellular unit).
3, thermosol bonding method:
Utilize the characteristic of plastics fusion, use hot melt to be one with the plastic pipe welding is compound.Thermosol is a kind of more effective mode of hot melt.Thermosol can adopt commercially available EVA, polyurethane, polyamide, polyester etc.In mould plastic pipe is arranged, the thermosol extruder head transfers to corresponding flow, and the junction between tube and tube is coated with, welding heat colloidal sol, should be furnished with cooling device simultaneously, implements cooling curing for the melting welding position.In mould, be one with being coated with welding heat colloidal sol between plastic pipe compound successively.
Advantage of the present utility model:
Utilize plastic pipe to obtain honeycomb article, production technology is simple, and the motor-driven selectivity of honeycomb ceramics of producing various materials and various honeycombs aperture, wall thickness is big, and equipment investment is low.
