Abstract
The invention discloses a manufacturing process for a high temperature-resistant and high pressure-resistant easy-open lid. The manufacturing process comprises the following steps of: selecting an aluminum sheet material; coating a colorless epoxy organic silicon coating on the sheet material surface which forms the outer surface of the easy-open lip and drying; coating a phenolic resin coating on the other surface and drying; and performing hacking, edge-rounding, molding, forming large and small bubbles, notching, edge-protecting, ring-nailing and gluing on the sheet material, and forming a finished product of the easy-open lid. The easy-open lid manufactured by the manufacturing process has high temperature resistance and high pressure resistance, and can perform high-temperature and high-pressure sterilization treatment without losing tightness.
Description
Technical field
The present invention relates to a kind of manufacture craft of high temperature high voltage resistant easy-open lid.
Background technology
Easy-open lid is as common a kind of packing assembly, be widely used in the milk powder packing, on chickens' extract packing and other some packaging materials for food, packing generally will have better seal, with the metal canned foods time, need earlier food to be put into metal can and sealing, and may vacuumize, high temperature high pressure sterilizing is handled, yet the performance of present easy-open lid high temperature high voltage resistant is also bad, therefore, in the process of high temperature high pressure sterilizing, the situation of easy-open lid generation miniature deformation appears easily, and finally cause it not seal fully, cause air penetration to enter, cause that content is rotten or rotten.
Summary of the invention
The manufacture craft that the purpose of this invention is to provide a kind of high temperature high voltage resistant easy-open lid.
The technical solution used in the present invention is:
A kind of manufacture craft of high temperature high voltage resistant easy-open lid, it may further comprise the steps:
1) selects aluminium plate, apply colourless epoxy organosilicon coating, at another side coating phenolic resin paint at the sheet material face that forms the easy-open lid outside face;
2) sheet material is hacked, round edge, moulding, the big vesicle of formation, indentation, guarantor limit, nail ring, injecting glue, formation finished product easy-open lid.
The thickness of described aluminium plate is 0.2-0.26mm.
Described colourless epoxy organosilicon coating is a kind of among FTH128, the FH131.
Described phenolic resin paint is JBH01-32.
Colourless epoxy organosilicon coating applied thickness is 1-2g/m2.
The phenolic resin paint applied thickness is 2-3g/m2.
The draw ring that the nail ring is used is the 209# draw ring.
The invention has the beneficial effects as follows:, can carry out that high temperature high pressure sterilizing is handled and loss of seal not with the easy-open lid high temperature high voltage resistant that this technology is made.
The specific embodiment
1) select aluminium plate, apply a kind of among colourless epoxy organosilicon coating FTH128, the FH131 at the sheet material face that forms the easy-open lid outside face, oven dry is in another side coating phenolic resin paint JBH01-32, oven dry; Colourless epoxy organosilicon coating applied thickness is 1-2g/m2, and the phenolic resin paint applied thickness is 2-3g/m2;
2) sheet material is hacked, round edge, moulding, the big vesicle of formation, indentation, guarantor limit, nail ring, injecting glue, formation finished product easy-open lid.
Selected aluminium plate is the sheet material of 8011 H18, H19 or 3 series alloys H18, H19.After tested, the tensile strength of sheet material is 285-290MPa, yield strength is 275-295MPa, stretch ratio is 4.8-5.0, Zhi Bei easy-open lid sterilization in the time of 30 minutes under 85-121 ℃ of situation thus, overall appearance no change, this is because used aluminium plate has mechanical strength preferably, the outside face of easy-open lid is coated with resistant to elevated temperatures colourless epoxy organosilicon coating simultaneously, and inside face is a phenolic coating, and the packing that contain these goods can carry out high temperature high pressure sterilizing to be handled.
