Problems solved by technology

[0003] In addition, the polyurethane sponge currently used, when the ambient temperature is very low, such as the winter temperature is less than 0 ℃, the hardness of the polyurethane sponge changes greatly, very hard, such as when the ambient temperature is high, such as when the summer temperature is greater than 30 ℃ , the polyurethane sponge will become very soft again, and when used as a household product, it will bring a different experience to the user
If the polyurethane sponge is used in industry, it will also make the product quality unstable

Embodiment Construction

[0015] Specific embodiments of the present invention will be further described in detail below. It should be understood that the description of the embodiments of the present invention here is not intended to limit the protection scope of the present invention.

[0016] The invention provides an environment-friendly polyurethane sponge capable of maintaining hardness. Its raw materials are composed of polyether polyol, polymer polyol, toluene diisocyanate, water, foaming agent, silicone oil and composite catalyst. For polyether polyols, it is a mixture of one or more polyether polyols with a molecular weight of 1000-5000, which itself is the basic raw material for the preparation of polyurethane sponges, so it is a prior art, and its characteristics and preparation methods are no longer described here. repeat. The polymer polyol can be formed by free radical graft polymerization at 90° C. to 120° C. under the protection of nitrogen by using basic polyether, vinyl monomer, and...

Abstract

The invention relates to environment-friendly polyurethane sponge capable of maintaining hardness. The environment-friendly polyurethane sponge is prepared from the following raw materials: polyether polyol, polymer polyol, toluene diisocynate, water, a foaming agent, silicone oil and a composite catalyst. The environment-friendly polyurethane sponge capable of maintaining hardness is prepared from the following raw materials in parts by weight: 42 to 75 parts of toluene diisocynate, 1.2 to 4.3 parts of water, 5 to 10 parts of a foaming agent, 0.5 to 3.0 parts of silicone oil and 0.1 to 1.0 part of a composite catalyst on the basis of 100 parts of the total weight of a mixture of polyether polyol and polymer polyol. In the mixture of the polyether polyol and the polymer polyol, the polyether polyol accounts for 80 to 90 parts, and the polymer polyol accounts for 20 to 10 parts. The composite catalyst is a compound catalyst of triethylene diamine and amine ether. The hardness of the polyurethane sponge is not greatly changed along with an environment temperature, the phenomenon that the polyurethane sponge is very soft in summer and very hard in winter is avoided, and the purpose of maintaining hardness can be achieved. Meanwhile, VOC and TVOC are basically avoided from production to use by a user, so the polyurethane sponge is safer and has less peculiar smell, and the purpose of environmental protection is achieved.

Description

technical field [0001] The invention relates to the technical field of household article manufacture, in particular to an environment-friendly polyurethane sponge capable of maintaining hardness. Background technique [0002] Ecological home and smart home are the two major trends of future home products. Among them, the development of ecological home furnishing presents a relatively rich development situation. How to strictly define ecological home is still a problem. Generally speaking, ecological home products should have raw materials, production processes and final products that are green, pollution-free, sustainable and recyclable. Environmentally-friendly polyurethane sponges prepared from natural plants that can maintain hardness fully meet the above characteristics. Therefore, household products prepared with plant foamed polyurethane as the core, such as mattresses, sofas and pillows, can be regarded as typical ecological household products. . But volatile orga...
