Summary of the invention
Main purpose of the present invention is to provide a kind of adhesive bonding method that can firmly connect the plastic parts of two plastic parts.
Another main purpose of the present invention is to provide a kind of can make sheet and the bonding firm and durable plasthetics of plastic cement carrier
The object of the present invention is achieved like this: the adhesive bonding method of this plastic parts is that sheet and plastic cement carrier is bonding, and it comprises the steps: 1) sheet is put into die cavity in order to the forming plastic cement carrier; 2) the plastic cement base-material of fusion is injected carry out injection mo(u)lding in this die cavity, make sheet and plastic cement carrier adhesion one, in this injection molding process, temperature range in the die cavity is 150 degrees centigrade ~ 280 degrees centigrade, the scope of injection pressure is 40 MPas ~ 280 MPas, and the scope of injection time is 3 seconds ~ 20 seconds; 3) cooling and the demoulding can obtain the plastic cement carrier that surface coverage has sheet.
The material of described sheet and plastic cement carrier is selected from following material: polypropylene, PETG, polystyrene, polyurethane and Merlon.
Sheet in the described method is a sandwich construction.
Described sheet comprises basic unit, and this basic unit's upper surface is equipped with two-layer at least patterned layer successively, is equipped with photic zone on the superiors patterned layer surface, is laid with raised line on this photic zone.
A kind of plasthetics by described adhesive bonding method preparation.
Compared with prior art, the present invention has following advantage: because sheet be by injection mo(u)lding with plastic cement carrier adhesion one, so can absciss layer between this two plastic parts, and durable attractive in appearance.
Description of drawings
Fig. 1 is the structural representation by the plasthetics of the adhesive bonding method preparation of plastic parts of the present invention.
Fig. 2 is the process chart of the adhesive bonding method of plastic parts of the present invention.
Fig. 3 is the partial enlarged drawing at P indication place among Fig. 1.
The specific embodiment
Please in conjunction with consulting Fig. 1 and Fig. 2, the adhesive bonding method of plastic parts of the present invention is that plastic cement carrier 1 and the method for sheet 2 by injection mo(u)lding are bonded into one.This sheet 2 can be lenticular lenses or plastic paper, and plastic cement carrier 1 can be stationery (as chi) or commodity (as glue tea making cup), and this carrier is that the plastic cement base-material by fusion forms through injection molding process in die cavity.The concrete steps of the adhesive bonding method of this plastic parts are as follows: 1) make sheet 2 (lenticular lenses or plastic paper); 2) this sheet 2 is put into the injection moulding die cavity, this injection moulding die cavity is the die cavity in order to forming plastic cement carrier 1; 3) under certain temperature and pressure, toward the interior plastic cement base-material that injects fusion of this die cavity, injection mo(u)lding then, in this process, the plastic cement base-material of fusion contacts and is adhered together with the surface of sheet 2; 4) cooling and demoulding can obtain the plastic cement carrier 1 that surface coverage has sheet 2.
In the above-mentioned injection molding process, temperature circle in the die cavity between 150 degrees centigrade and 280 degrees centigrade, boundary is between 3 seconds and 20 seconds between 40 MPas and 200 MPas, during injection for injection pressure circle, cool time circle is between 4 seconds and 20 seconds.The material of this sheet 2 and plastic cement carrier 1 is selected from plastic cement materials such as following material: PP (polypropylene) material, PET (PETG) material, PS (polystyrene) material, PU (polyurethane) material or PC (Merlon) material.For plastic cement carrier 1, temperature in the required die cavity and injection pressure are to change along with the variation of the wall thickness of plastic cement carrier 1, and general wall thickness is big more, and then needed temperature and pressure is also big more.When plastic cement carrier 1 volume is big more, the also corresponding growth of injection time, the needed temperature and pressure of moulding also increases.For sheet 2, its thickness is big more, then corresponding growth of injection time, the also corresponding increase of temperature and pressure that injection mo(u)lding is required.The wall thickness of plastic cement carrier 1 is relevant with the thickness of the sheet 2 that will adhere, the ratio of the thickness of the wall thickness of this plastic cement carrier 1 and sheet 2 is not between the two can absciss layer and required bondability is decided, as when the thickness that needs bonding sheet 2 is 0.5 millimeter, then the thickness of plastic cement carrier 1 is 1.5 millimeters.
Plasthetics by the preparation of the adhesive bonding method of above-mentioned plastic parts comprises plastic cement carrier 1 and covers this plastic cement carrier 1 lip-deep sheet 2 that this sheet 2 is one-body molded by injection moulding with plastic cement carrier 1.
Please in conjunction with consulting Fig. 3, its expression will have the sheet 2 of pattern transform effect and make a relief painting cup with plastic cement carrier 1.In the present embodiment, this sheet 2 is lenticular lenses, and its thickness circle is between 0.3 millimeter and 0.4 millimeter.This sheet 2 is a sandwich construction, it comprises basic unit 21, be equipped with two-layer at least patterned layer 22 successively at these basic unit's 21 upper surfaces, on the superiors' patterned layer 22 surfaces, be equipped with photic zone 23, these photic zone 23 surfaces are laid with some raised lines 231, refraction and reflection by each raised line 231 make change in pattern.This plastic cement carrier 1 is the glue cup, and its material is a PP material, and wall thickness circle of this glue cup is between between 1 millimeter and 1.5 millimeters.The manufacturing process of this relief painting cup is as follows: 1) make lenticular lenses, and the length of this lenticular lenses is slightly larger than the outer circumference of glue cup; 2) lenticular lenses is put into injection moulding die cavity in order to moulding glue cup; 3) under certain temperature and pressure situation, toward the interior PP plastic cement base-material that injects fusion of die cavity, through injection mo(u)lding, make sheet and glue cup adhesion one, in the manufacturing process of this relief painting cup, temperature in this die cavity is that to 95 MPas, the injection time is 4 seconds to 6 seconds to injection pressure circle in 70 MPas between 220 degrees centigrade and 230 degrees centigrade of boundary's; 4) cooling and the demoulding can obtain this relief painting cup, and roughly be 4 seconds to 6 seconds this cool time.
Because sheet 2 be by injection mo(u)lding with plastic cement carrier 1 adhesion one, so can absciss layer between this two plastic parts 1,2, and durable attractive in appearance.
