Embodiment Construction

[0013] The present invention is further described the present invention with several representative examples below: in the raw material of application and weight portion proportioning thereof, amount is maximum be polyether polyol and toluene diisocyanate, each accounts for 30-70 weight portion (below the same) ), which is determined according to the density requirements of the foam composite material. If the density is high, the proportion of polyether polyol should be increased, and the proportion of toluene diisocyanate and other foaming aids should be reduced. If the density is low, the opposite is true.

[0014]

[0015] (Note: The binary and ternary in the table are the abbreviations of polyether diol and polyether triol respectively)

[0016] The production steps of this foam composite material are: (1) the production of bamboo charcoal powder: the bamboo is split into fragments less than 30cm in length or with bamboo processing waste except sawdust, placed in a carbo...

Abstract

The invention relates to a bamboo charcoal polyurethane foam composite material, which comprises the following raw materials in portion by weight: 30 to 70 portions of polyether polyol, 30 to 70 portions of toluene di-isocyanate, 5 to 10 portions of bamboo charcoal powder and a dispersing agent thereof, and a certain amount of mold-release agent, catalyst, blowing promoter and the like. The production method comprises four production steps of the production of the bamboo charcoal powder, the preparation of composite bamboo charcoal powder, the preparation of a prepolymer, and the preparation of the foam composite material. The bamboo charcoal polyurethane foam composite material is suitable for manufacturing compartment sandwich materials, sofas, seat cushions, mattresses and the like, is soft and comfortable and is rich in elasticity, has the advantages of strong performances of absorbing free formaldehyde, releasing negative ions and emitting far infrared rays, and is advantageous for the health of human bodies.

Description

【Technical field】 [0001] The invention relates to a polyurethane foam composite material mixed with bamboo charcoal powder and a production method thereof. 【Background technique】 [0002] Polyurethane foam materials have been widely used in people's daily life, such as interlayer materials for carriages, seats, beds, pads, etc. Most of them use their porous and elastic characteristics to give people a soft and comfortable feeling. But although ordinary foam material can absorb moisture, it is not easy to distribute moisture, and it is easy to breed germs due to the smell of dirt. For this reason, CN1865326 discloses "a kind of bamboo charcoal sponge and its preparation method", and CN1478817 discloses "antibacterial elastic polyurethane nanocomposite material and its preparation". Method", it is beneficial to increase and improve the moisture absorption and drying, antibacterial and deodorizing properties of the foamed material. But the bamboo charcoal in the CN1865326 pate...
