AI Technical Summary

Problems solved by technology

Existing polyurethane sponges usually cannot take into account both hardness and elasticity. Additives are needed to increase the rebound rate of polyurethane under the condition of sufficient hardness. However, the added additives will cause compatibility problems in the system. Cause defects such as irregular cells, foam collapse, and cracking of polyurethane materials, which limit the application of polyurethane sponge in production and life
At the same time, polyurethane products have the problem of poor weather resistance. They will cause yellowing, brittleness, and decline in mechanical properties when placed for a long time or under the action of light and heat. This also limits the use of polyurethane in furniture products for long-term use, especially in the field of sofas. The application reduces the comfort experience of the sofa

Embodiment 1

[0039] This embodiment provides a high-resilience, pressure-resistant sofa filler, and the material of the sofa filler is polyurethane sponge.

[0040] The raw materials of the polyurethane sponge include: in parts by weight, 56 parts of butter PPG, 24 parts of isocyanate, 6 parts of polysiloxane, 4 parts of alcohol additives, 1 part of organotin catalyst, 5 parts of solvent and 3 parts of water.

[0041] The raw material of described polyurethane sponge also comprises 18 parts of POP (polymer polyol).

[0042] The butter PPG was purchased from Guangzhou Suibang Polymer Material Technology Co., Ltd.

[0043] The POP was purchased from Guangzhou Hongyu Trading Co., Ltd., the model is POP-36 / 28.

[0044] Described polysiloxane is amino-modified polysiloxane, and the kinematic viscosity of amino-modified polysiloxane is 1500mm 2 / s (25°C), purchased from Dongguan Jianmeng Chemical Co., Ltd.

[0045] The isocyanate is MDI, purchased from Guangzhou Chengtian Chemical Co., Ltd. ...

Embodiment 2

[0052] A high-resilience, pressure-resistant sofa filling, the specific implementation is the same as that of Example 1. The difference is that POP is not added.

Embodiment 3

[0054] A high-resilience, pressure-resistant sofa filling, the specific implementation is the same as that of Example 1. The difference is that the weight portion of POP added is 8 parts.

Abstract

The invention relates to the field of sofa manufacturing, in particular to a sofa filler with high resilience and sag resistance and a sofa thereof. The sofa filler with high resilience and sag resistance is made of polyurethane sponge. The polyurethane sponge with excellent mechanical properties and uniform pore bubbles is obtained by performing raw material and process limitation on the sofa filler, the prepared sofa has excellent elasticity and comfort, the formaldehyde content meets the industrial standard, and the polyurethane sponge is green, environmentally friendly and wide in application prospect.

Description

technical field [0001] The invention relates to the field of sofa manufacture, in particular to a high-rebound, pressure-resistant sofa filling and a sofa thereof. Background technique [0002] As an essential item in home life, sofa occupies an increasingly important share in the furniture market. With the improvement of people's living standards and health awareness, the requirements for sofa comfort are getting higher and higher. As the main component of the sofa, the sofa filling directly affects the experience of the sofa. [0003] Polyurethane sponge has the advantages of low density and small compression set, and has been widely used in automobiles, shoe materials, furniture, clothing and other living fields. Existing polyurethane sponges usually cannot balance both hardness and elasticity. It is necessary to add additives to improve the rebound rate of polyurethane under the condition of sufficient hardness. However, the added additives will cause compatibility pro...
