Abstract
The invention provides a process for combining phenolplast and elastic mass; it belongs to plastic technology field. The invention solves the problem of complex process and loose combination. The process of the invention is: (1). Injection molds phenolplast base: the phenolplast material is put into the injection molding machine, becomes phenolplast base; (2). Coarse process: carries on coarse process to the surface bonded by phenolplast base and elastic mass; (3). Commonly injection molding: the coarsely processed phenolplast base is put into forming mold as parent body, then puts the elastic material into injection molding machine, the product is formed. The elastic mass is thermoplastic elastic mass. The process provided by the invention is simple and convenient.
Description
Technical field
The invention belongs to the plastics technology field, the technology of particularly a kind of phenoplasts and elastomer-bonded.
Background technology
Phenoplasts are owing to have advantages such as thermosetting is good, high temperature resistant, have a wide range of applications in occasions such as the handle of various utensils or equipment or handrails.People usually also at its arranged outside elastomer, increasing elasticity, frictional force and the feel of product, and play anti-skidding, heat insulation effect when using phenoplasts and make product such as handle or handrail.
But, elastomer can't be directly and phenoplasts bonding.The existing method that elastomer is combined with phenoplasts has two kinds:
A kind of is that elastomer is made gum cover or inserts, directly is enclosed within or is set on the phenoplasts matrix, though this method is feasible, its shortcoming is that gum cover or inserts that elastomer is made are loosening, firm inadequately easily;
Another kind is to be total to injection moulding with elastomer again after the surface of phenoplasts matrix applies glue, the weak point of this method is that glue is aging easily, elastomer can become flexible because of glue is aging, and the production technology of this method is very complicated, causes the cost of product higher.
Summary of the invention
The objective of the invention is provides a kind of phenoplasts of novelty and the technology of elastomer-bonded at existing phenoplasts and the existing the problems referred to above of elastomer-bonded, and it is had in conjunction with firm, production technology characteristic of simple.
Purpose of the present invention can realize by following technical proposal: these phenoplasts follow these steps to carry out with the technology of elastomer-bonded:
(1), injection moulding phenoplasts matrix: the phenoplasts raw material packed into carry out injection moulding in the injection machine, become the phenoplasts matrix;
In this process, the temperature of injecting machine material tube is controlled in 55～80 ℃, and the temperature of mould is in 165～180 ℃, and the pressure of injection moulding is in 70～90Mpa, and the time that pressurize is solidified is in 70～80 seconds in 5～12 seconds the time of injection moulding during injection mo(u)lding.
(2), coarse processing: to carrying out coarse processing with the surface of elastomer-bonded on the phenoplasts matrix;
The method of this coarse processing both can be directly the phenoplasts matrix surface to be carried out coarse processing, also can adopt the dies cavity to the phenoplasts matrix to carry out the rough surface processing, thereby produce shaggy phenoplasts matrix.
Phenoplasts also are bakelite or bakelite, are thermosetting plasticses, and the back molecule that is heated can not melt.Because phenoplasts and elastomer have bigger difference on polarity, so the phenoplasts matrix surface must pass through coarse processing, and impurity such as water, greasy dirt can not be arranged, and between ability and the elastomer adhesion preferably arranged.
(3), injection mo(u)lding altogether: the phenoplasts matrix through coarse processing is put into mould as parent, carry out injection moulding in the injection machine of again the elastomer raw material being packed into, get finished product.
In this process, the temperature of injecting machine material tube is controlled in 165～220 ℃, and the temperature of mould is in 20～50 ℃, and the pressure of injection moulding is in 60～80Mpa, and the time that pressurize is solidified is in 20～40 seconds in 5～12 seconds the time of injection moulding during injection mo(u)lding.
In above-mentioned technology, described elastomer is that thermoplastic elastomer (TPE) (is abbreviated as: TPE).
Compared with prior art, the present invention has adopted the method for common injection mo(u)lding, and its technical process is simple and convenient.Because phenoplasts and elastomeric contact-making surface have carried out coarse processing in technical process, and do not use bonding agent such as glue, make between the two adhesion big, be connected firmly the phenomenon that is not prone to separation or comes off after long-term the use.
Description of drawings
Accompanying drawing is the cutaway view that adopts the handle that technology of the present invention makes.
Among the figure, 1, the phenoplasts matrix; 2, elastomer.
The specific embodiment
Two following embodiment adopt technology provided by the invention to make the specific operation process of handle as shown in the figure.
Embodiment one
At first, the phenoplasts raw material is packed into carry out injection moulding in the injection machine.The temperature of injecting machine material tube is 55 ℃, and the pressure of injection moulding is 80Mpa, and the temperature of mould is 165 ℃, and the time of injection moulding is 8 seconds during injection mo(u)lding, and the time that pressurize is solidified is 70 seconds.Become phenoplasts matrix 1 by injection moulding.
Then, directly coarse processing is carried out on the surface that combines with elastomer 2 on the phenoplasts matrix 1.Can not there be impurity such as water or greasy dirt on processed surface.
At last, putting into the handle mould as parent through the phenoplasts matrix 1 of coarse processing, injection mo(u)lding altogether obtains the handle finished product in the injection machine of again the elastomer raw material being packed into.In this process, the temperature of injecting machine material tube is 165 ℃, and the temperature of mould is 25 ℃, and the pressure of injection moulding is 65Mpa, and the time of injection moulding is 5 seconds during injection mo(u)lding, and the time that pressurize is solidified is 25 seconds.The density of elastomer 2 is 1.05g/cm, and shrinkage factor is 1.8%.
Embodiment two
At first, the phenoplasts raw material is packed into carry out injection moulding in the injection machine.The temperature of injecting machine material tube is 80 ℃, and the pressure of injection moulding is 90Mpa, and the temperature of mould is 180 ℃, and the time of injection moulding is 12 seconds during injection mo(u)lding, and the time that pressurize is solidified is 80 seconds.Before injection moulding, the dies cavity of phenoplasts matrix 1 is carried out rough surface handle.Then, become phenoplasts matrix 1, and the surface of phenoplasts matrix 1 there is certain roughness by injection moulding.
