The liquid adhesive is made by mixing polyvinyl acetate solution with a mass percentage of 55%, polyvinyl alcohol solution with a mass percentage of 5%, dibutyl phthalate, and sec-butyl acetate together, wherein the volume ratio of the polyvinyl acetate solution, the polyvinyl alcohol solution, the dibutyl phthalate, and the sec-butyl acetate is 1˜1.2:15˜17:0.3˜0.5:2.5˜3.0. The organic solvent is alcohol for example, but not limited to alcohol.
Three ceramic-and-plastic composite articles 10 were made by the process described above-. The drawing force between the ceramic part 11 and the plastic part 13 of each composite article 10 was tested using a SE Precision Load Tester (Model: 1220 (H)S). Each composite article 10 was tested for six times. The test results are shown in Table 1. The test results indicates that the drawing force between the ceramic part 11 and the plastic part 13 is strong, so the ceramic part 11 and the plastic part 13 can bond with each other firmly.
a plastic part; and
an adhesive layer connecting the ceramic part to the plastic part;
wherein the adhesive layer comprises polyvinyl acetate, polyvinyl alcohol, dibutyl phthalate, and sec-butyl acetate.
2. The composite article as claimed in claim 1, wherein the adhesive layer is obtained by drying a liquid adhesive, the liquid adhesive comprises polyvinyl acetate, polyvinyl alcohol, dibutyl phthalate, sec-butyl acetate, and organic solvent.
3. The composite article as claimed in claim 2, wherein the organic solvent is alcohol.
4. The composite article as claimed in claim 2, wherein the liquid adhesive comprises polyvinyl acetate solution having a mass percentage of 55%, polyvinyl alcohol solution having a mass percentage of 5%, dibutyl phthalate, and sec-butyl acetate, and the volume ratio of the polyvinyl acetate solution, the polyvinyl alcohol solution, the dibutyl phthalate, and the sec-butyl acetate is 1˜1.2:15˜17:0.3˜0.5:2.5˜3.0.
5. The composite article as claimed in claim 1, wherein the adhesive layer has a thickness of about 20 μm to about 40 μm.
6. The composite article as claimed in claim 1, wherein the plastic part is made of a resin having a molding temperature lower than 170° C.
7. A method for making a composite article, comprising:
injection molding a plastic part on the adhesive layer of the ceramic part.
8. The process as claimed in claim 7, wherein the liquid adhesive is made by mixing polyvinyl acetate solution with a mass percentage of 55%, polyvinyl alcohol solution with a mass percentage of 5%, dibutyl phthalate and sec-butyl acetate together, and the volume ratio of the polyvinyl acetate solution, the polyvinyl alcohol solution, the dibutyl phthalate and the sec-butyl acetate is 1˜1.2:15˜17:0.3˜0.5:2.5˜3.0.
9. The process as claimed in claim 7, wherein the organic solvent is alcohol.
10. The process as claimed in claim 7, wherein the drying of the liquid adhesive is carried out at a temperature of 40° C. for at least 30 min or at a room temperature for at least 24 hours.
11. The process as claimed in claim 7, wherein the adhesive layer has a thickness of about 20 μm to about 40 μm.
12. The composite article as claimed in claim 7, wherein the plastic part is made of a resin having a molding temperature lower than 170° C.
