Problems solved by technology

[0002] Sponge products have been gradually popularized in people's lives, including seats, sofas, mattresses and other household items made of sponges. Polyether polyols are the main raw materials for the production of polyurethane sponges. Polyether polyols are generally used in the production of polyurethane sponges. Alcohols usually use petroleum-based polyether polyols. However, polyurethane made of petroleum-based polyether polyols has high stability and is difficult to decompose in a natural state; making them non-degradable is not conducive to environmental protection and sustainable development. The expansion of the application field of sponge products requires a large amount of sponge supply in the market. Because there are many performance defects in the existing sponges, the feel and comfort of natural sponges are very different, and the use of artificial sponges in the prior art is just There are many security risks

Embodiment 1

[0023] Embodiment 1, a kind of green environmental protection sponge adopts the following method to make, add a certain amount of water to the reaction vessel, heat to 80 to 90 degrees Celsius, then add 75 to 85 kilograms of melamine; 40 to 45 kilograms of polyester Elastomer TPEE; 25 to 30 kilograms of polyether polyol; 5 to 8 kilograms of plant fiber; 2 to 4 kilograms of animal collagen; after fully stirring these mixtures for 15 minutes, add 1 kilogram of foaming aids, and prepare them after the reaction is completed. Get the green environmental protection sponge of the present invention. Among them, the polyester elastomer TPEE is produced by the polymerization reaction of dimethyl terephthalate, 1,4-butanediol and polybutanol; the polyether polyol is composed of an initiator (a compound containing active hydrogen groups) and Ethylene oxide (EO), propylene oxide (PO) and butylene oxide (BO) are prepared by polyaddition; the plant fibers include coconut fibers, kapok fibers...

Embodiment 2

[0024] Embodiment 2, a kind of green environmental protection sponge adopts the following method to make, add a certain amount of water to the reaction vessel, heat to 80 to 90 degrees Celsius, then add 80 kilograms of melamine to it successively; 42.5 kilograms of polyester elastomer TPEE; 27.5 kg of polyether polyol; 6.5 kg of plant fiber; 3 kg of animal collagen; 3 kg of calcium carbonate and 4 kg of silicon carbonate. After fully stirring these mixtures for 15 minutes, add 2 kilograms of foaming aids, and treat that its reaction finishes and just makes pure natural environmental protection sponge of the present invention. Among them, the polyester elastomer TPEE is produced by the polymerization reaction of dimethyl terephthalate, 1,4-butanediol and polybutanol; the polyether polyol is composed of an initiator (a compound containing active hydrogen groups) and Ethylene oxide (EO), propylene oxide (PO) and butylene oxide (BO) are prepared by polyaddition; the plant fibers i...

Abstract

The invention discloses a pure natural environment-friendly sponge. The pure natural environment-friendly sponge is prepared from the following components in parts by weight: 75-85 parts of melamine, 40-45 parts of polyester elastomer TPEE, 25-30 parts of polyether polyol, 5-8 parts of plant fibers and 2-4 parts of animal collagen. The green environment-friendly sponge is close to natural sponge, extensive in use of medical science and everyday life, and can be used for preparing household articles of paint brushes, linings of steel helmets, seats, sofas, seat cushions and the like. The sponge is soft in hand feeling, and has a surface shape which is remarkable in slow resilience, capable of absorbing impact force and reducing vibrations, strong in low resilience force release capacity, and capable of adapting to stress through stress relaxation to press. Meanwhile, even the pure natural environment-friendly sponge is used in summer, a user does not feel hot due to the excellent heat dissipation function, and the user feels cool and comfortable while using the sponge main body disclosed by the invention in summer due to addition of calcium carbonate and silicon carbonate, so that the refrigeration operating frequency of an air conditioning fan is reduced, and effects of saving energy and reducing emission are achieved.
