Embodiment Construction

[0033] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] Such as figure 1 Shown: An elastic cushion core for seat cushions is made of silicone rubber connected to compressed springs. The elastic cushion core is an overall structure including 1, 2, 3, and three parts; 1. The connection layer between the silicone rubber and the spring upper support ring, .The effective ring part of the spring, 3. The connection layer between the silicone and the support ring at the lower end of the spring.

[0035] Such as figure 1 figure 2 Shown: Ventilation holes 4 and 5 are designed on the upper and lower layers of the elastic cushion core. The number of vent holes 4 is equal to that of the springs. One spring corresponds to one vent hole. The inner diameter of circle, vent hole 5 is in the middle of four springs.

[0036] Such as image 3 Shown: Cotton fiber 7 is added in the connecting layer of the silica gel and the spring...

Abstract

The invention discloses an elastic cushion core for a cushion and a preparation method thereof. The elastic cushion core is formed by connecting silicone rubber with compression springs. The elastic cushion core is of an integrated structure and comprises an upper part, a middle part and a lower part, wherein the upper layer is a connecting layer of silicone rubber and spring upper end supportingrings, the middle part is an effective ring part of the springs, and the lower layer is a connecting layer of the silicone rubber and spring lower end supporting rings; a plurality of air holes are designed in the upper and lower layers of the elastic cushion core, and cotton fiber is additionally placed in the connecting layers of the silicone rubber and the spring upper and lower end supportingrings. According to the preparation method, the liquid silicone rubber is vulcanized in a mould to be connected with the compression springs. The elastic cushion core has the advantages of good flatness, breathability, high elasticity, no toxicity, no odor, no noise, high temperature resistance, low temperature resistance, flexibility, comfort and the like.

Description

technical field [0001] The invention relates to the technical field of cushions, in particular to an elastic cushion core for a cushion and a preparation method thereof. Background technique [0002] Most of the car cushions, car cushions, chair cushions, sofa cushions, etc. used in our life use foaming materials (sponge) or springs as cushion cores. Disadvantages of foam material cushion core; poor air permeability and not durable elasticity. The spring gasket has been loved by everyone because of its high elasticity and air permeability. However, the connection technology of the spring gasket and the spring still needs to be improved and improved. The existing connection technologies include steel wire spring connection, metal buckle connection, and cloth bag adhesive connection. Disadvantages of cushion cores produced by steel wire threaded springs and metal buckles connecting compression springs 1; many metal contact points are prone to noise during use. Disadvantages 2...
