Problems solved by technology
However, the slow-rebound foam is not easy to dissipate the absorbed water, so it is easy to stink and nourish bacteria, which is not conducive to hygiene; and the slow-rebound foam itself has no specific adsorption and health functions; in addition, the slow-rebound foam mostly uses tin-based catalysts, So that the foam still contains a small amount of but more toxic substances, which is not good for health and environmental protection

Embodiment
[0014] Put the truncated bamboo or bamboo processing leftovers into a carbonization furnace and burn them at a temperature of about 700°C for 2 hours, cool them down to room temperature naturally, take them out, crush them and sieve them, and collect 200-320 mesh (0.071mm- 0.045mm) bamboo charcoal, washed with water and dried to dryness for later use.
[0015] Preparation of composite washed dry powdered bamboo charcoal with the prepared washed dry powdered bamboo charcoal
[0016] Uniform dispersant 60NS is mixed in a ratio of 1:0.05 by weight for later use.
[0017] Add the composite washed dry powdered bamboo charcoal, polyether polyol, water, glycerin, surfactant, and catalyst into the mixing tank according to the ratio in Table 1. After stirring evenly, keep the material temperature at 24-28°C, and then Then add Cosmonate T-80 according to the ratio in Table 1, stir rapidly for 7 to 10 seconds, and then quickly follow the conventional operating procedures.

Abstract
The invention discloses a method for producing a bamboo charcoal slow-resilience foam material, which comprises the following steps of: 1, preparation of washed absolute dry powdery bamboo charcoal; 2, preparation of composite washed absolute dry powdery bamboo charcoal; and 3, production of bamboo charcoal slow-resilience foam: adding 0.1 to 5 weight parts of composite washed absolute dry powdery bamboo charcoal, 100 weight parts of Actcol LR, 1 to 2 weight parts of H2O, 0 to 4 weight parts of glycerol, 0.5 to 1 weight part of catalyst and 1 to 2 weight parts of surfactant into a mixing barrel, stirring the mixture and then adding 45 to 60 weight parts of toluene diisocynate, quickly stirring the mixture, feeding the mixture into a mold, and releasing a product from the mold to obtain the bamboo charcoal slow-resilience foam. The method has the advantages of simplicity, convenience, one-time investment, easy operation and low cost; and the bamboo charcoal slow-resilience foam material product has the advantages of comfortableness, good air permeability, strong moist adjustment, no toxic substances such as tin base and the like, no pungent smell, capability of adsorbing harmful gas and anionic and infrared health-care function.
Description
technical field [0001] The invention relates to a production method of a bamboo charcoal slow rebound foam material containing washed dry powdered bamboo charcoal (200-320 mesh). The powdered bamboo charcoal participates in the foaming process and is evenly distributed in the foam material. Background technique [0002] Slow resilience foam is called memory foam and zero pressure foam. Its unique feature is that it can conform to the shape of the load, so that the contact area is maximized, the stress gradient is minimized, the stress concentration point can be relieved, and there is no local backlog and Tingling feeling, with shape memory, sound absorption, shock absorption and other functions, can be used as shock absorber, sound absorber, shock absorber, and is a good interior and home material. However, the slow-rebound foam is not easy to dissipate the absorbed water, so it is easy to stink and nourish bacteria, which is not conducive to hygiene; and the slow-rebound fo...
