Description
Technical field
The invention relates to a kind of with hot melt adhesive made reinforcing chip and method for making and reinforcement thereof as the bonding setting of object, especially refer to a kind of master mold and male model that has plastic reinforcing chip in order to bonding and reinforcement object in advance, and preparation hot melt adhesive, and hot melt adhesive is heated into molten and injects in the die cavity of master mold, moulding with master mold and male model that mould closes to hot melt adhesive, after cooling off and moulding is the reinforcing chip of composition with the hot melt adhesive, allow this reinforcing chip be subjected to reinforcement place for adhering on object, through suitably heating and pressurizeing, and make reinforcing chip and this object bonding, after cooling, can make reinforcing chip be bonded on the object and harden to be subjected to the reinforcement setting thing of reinforcement place as this object, make to reach convenient, reduce cost and purpose such as environmental protection.
Background technology
General two soft mutual applying objects, in order to increase the suitable intensity between this two applyings object, so that this two articles corner obtains firm setting with bonding, the space that present existing technology all can be situated between between this two articles corner is situated between and puts a reinforcing chip, have the bent angle shape similar and the suitable hardness of reinforcing chip with this reinforcing chip, and then this two soft objects corner suitably propped up and formalize to this two articles corner; Wherein, in this known technology, its two articles must paste admittedly mutually could constitute a complete finished product, and reinforcing chip Jie puts behind this two articles, because known reinforcing chip generally all is the material ejection formations such as PVC (for example common counter reinforcing chip promptly is) not have viscosity, and make this two articles in order to reach, known adherent operating method, be on the PVC reinforcement is unilateral, to coat toluene earlier, suitably destroy the reinforcing chip surface with toluene, on the ruined surface of reinforcing chip, coat stick again, again reinforcing chip is situated between put between two articles, carry out bonding; Yet, this kind known technology, not only the entire operation process complicated with inconvenience, the PVC material be difficult for to decompose, and causes environmental pollution easilier.
At present in order to provide low temperature can melt (general temperature of fusion is between 65 ℃-180 ℃), and has environment-friendly function, nonflammable, nontoxic and can not cool off the stick of embrittlement, known existing on the market hot melt adhesive (hot-meltadhesive), as No. the 146044th, Taiwan patent announcement and announce the patent case No. 208025, and the fundamental component of general common hot melt adhesive consists predominantly of: polymer weight polymer (High Molecular WeightPolymer), solidify synthetic elastomer (Synthetic Elastomer) and resin (Resin).And various hot melt adhesive all is according to its actual demands of applications and slightly different at Chemical Composition, but main commonly used has been exactly about vinyl polymerization body (Vinyl Polymers), their format is formed, promptly be ethene (ethylene) and its different amount Molecularly Imprinted Polymer (copolymers), atypic propylene (amorphous polypropylenes) and thermoplastic elastomer (thermoplastic rubbers).For example a kind of more traditional hot melt adhesive (hot-melt adhesive) is exactly by ethene (ethylene), vinylacetate (vinyl acetate) and some additives (additives) (as thermoplastic polymer (thermoplastic polymers), wax (waxes) etc.).Though above-mentioned known hot melt adhesive has possessed many advantages, yet, not at present known not seeing hot melt adhesive according to pasting the folded molded and shaped in advance technology of object setting place, known hot melt adhesive all is simply to be pressed into strip when making, sheet or columned form, allow the user must be by heat seeling coating device (waiting No. the 275254th, thermosol gelgun or Taiwan patent announcement and spreadometer such as No. 169548 for No. 174706) as No. the 141389th, Taiwan patent announcement and bulletin, hot melt adhesive could be coated on the object for bonding usefulness, thereby cause the raising of costs such as inconvenience in the use and machinery equipment.
