Abstract
The invention relates to a method for producing an automotive rear shelf by using fiberglass reinforcing honeycomb paper core as base materials. The method is characterized by including following process steps: firstly, laying fiberglass felt on the upper side and the lower side of the honeycomb paper core as the base materials; secondly, uniformly spraying polyurethane rubber on a contact surface of the fiberglass felt with the honeycomb paper core; thirdly, sending the base materials processed at the second step to a mold and performing compression molding on a former to obtain a semifinished product; fourthly, placing the semifinished product obtained after going through the compression molding at the third step on a cooling jig for cooling shaping at the normal temperature; fifthly, spraying hot melt glue on one face of the semifinished product obtained after going through the cooling shaping at the fourth step and bonding nonwoven fabrics after glue spraying; and sixthly, mounting fasteners, hot cotton and children seat decorative covers on the semifinished product obtained at the fifth step, testing, and boxing to obtain the automotive rear shelf. By the method for producing the automotive rear shelf by using the fiberglass reinforcing honeycomb paper core as the base materials, problems of poor deadening effect and strength and strong smell of the rear shelf are solved, and rigidity is good.
