Abstract

The invention discloses a production process of a composite pad. The production process of the composite pad comprises the following steps of carding and needling coconut fibers by using a needling machine; spraying glue on the front surface and the back surface of the coconut fibers by using a flaking machine for flaking to obtain a coconut fiber sheet; cutting the coconut fiber sheet according to requirements; putting the cut coconut fiber sheet into a gum dipping box to be integrally dipped with gum; putting the gum-dipped coconut fiber sheet into a first mold for shaping to obtain a skeleton of the composite pad; putting the framework into a vulcanization box for vulcanization; putting the vulcanized skeleton into a second mold, and injecting a foaming material into the second mold; and removing the second mold to obtain the composite pad. The coconut fiber is moderate in hardness; and the foaming material has high resilience and can be well matched with the curve of a human body,so that seamless fitting is realized. According to the composite pad, the framework is made of the coconut fibers and is wrapped with the foaming material, so that the use strength and the air permeability of the composite pad are guaranteed, and the comfort of fitting with a user is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of production of composite mats, and more particularly, to a production process of composite mats. Background technique [0002] With the development of the automobile industry, drivers and passengers have higher and higher requirements for the comfort of car seats, and one of the important criteria for evaluating the comfort of car seats is whether the composite cushion can eliminate the fatigue of drivers and passengers during driving. When the driving environment is harsh, the composite pad needs sufficient softness, elasticity, fit and strength to eliminate the impact of bumps and other adverse factors on the driver and occupant, and better protect the driver and occupant. [0003] In terms of long-distance logistics transportation, drivers and passengers need to contact the composite pad for a long time, which requires the backrest to have a certain degree of breathability to ensure a good driving exper...
