摘要：通過雙螺桿擠出機(jī)擠出自制的聚丙烯原料，擠出的料直接進(jìn)入自制的浸漬設(shè)備，同時(shí)把玻纖通入自制的浸漬設(shè)備，使玻纖充分熔融浸漬，初步得到連續(xù)玻纖增強(qiáng)聚丙烯片材。然后將所得片材通過平板硫化機(jī)層壓得到連續(xù)玻纖增強(qiáng)聚丙烯片材。力學(xué)性能測試結(jié)果表明：隨著PP-g-MAH用量的增加，玻纖片材的拉伸強(qiáng)度呈上升趨勢，斷裂伸長率并沒有明顯變化。隨著相容劑PP-g-MAH用量的增加彎曲強(qiáng)度呈上升趨勢，到達(dá)一定值時(shí)，彎曲強(qiáng)度變化不大。玻纖的加入使得聚丙烯的拉伸強(qiáng)度迅速提高，玻纖含量的增加，片材的拉伸強(qiáng)度是先增大后降低。斷裂伸長率在加入玻纖后迅速降低，隨著玻纖含量的變化，連續(xù)片材斷裂伸長率變化不大。彎曲強(qiáng)度隨著玻纖的加入后明顯提高，當(dāng)玻纖含量到達(dá)一定程度時(shí)，彎曲強(qiáng)度有所下降。 關(guān)鍵詞：熔融浸漬；連續(xù)玻纖；聚丙烯；力學(xué)性能
Abstract：Polypropylene materials ,the extrusion of material directly put into a homemade dipping equipment, are extruded through the twin-screw extruder.At the same time, we put the fiberglass into the homemade dipping equipment to make the fiberglass full melt impregnation. We can get the initial continuous glass fiber reinforced polypropylene sheets. And then make the sheets by vulcanizing machine laminating to get the continuous glass fiber reinforced polypropylene sheets. The mechanical properties of the test results show that: With the increase in the amount of PP-g-MAH , the tensile strength of glass fiber sheet shows upward trend, the elongation at break did not change significantly. With the amount of compatilizer of PP-g-MAH was increased, the flexural strength shows upward trend ,when reached a certain value, the bending strength changed little. With the attend of fiber glass ,the tensile strength of polypropylene is rapidly increasing. With the increase of glass content, the tensile strength of the sheet is first increased and then decreased. Elongation at break decreased rapidly after the attend of the fiber glass .With the changes of the content of glass fiber ,the continuous sheet’s elongation at break changed little. With the accession of the glass fiber, the flexural strength significantly improved, when the glass content reaches a certain level, the bending strength has declined.Key words: melt impregnation; continuous glass; polypropylene; mechanical properties.
