[0062] Formulation 4-4 includes 80 parts of the following weight: 80 parts of the sixth polyol 20, 0.5 parts of the third polyol 20, hydrolyzed silicone surface activator, 1.45 parts of water, 0.1 parts of the first amine catalyst. 0.3 parts of the second amine catalyst, 0.1 parts of octanoate, and 37 parts of the bio-based TDi.
[0063] The first amine catalyst is NIAX A-1, the second amine catalyst is NIAX A-33, and the fourth polyol is a multi-functional polyether polyester, and the functionality is 3, the hydroxyl value is 35 mgkOH / g, suitable for more Mold polyurethane sponge, such as a car seat, etc., the third polyol is a high solid content polymer polyether polyol, a hydroxyl value of 28 mgKOH / g (solid content 45%), and the sixth polyol is a low molecular weight polyether The polyol, functionality is 3, and the hydroxyl value is 235 mgKOH / g, and the seventh polyol is a high solid content polymer polyether polyol, and the hydroxyl value is 20 mgKOH / g (solid content of 28%).
[0064] A method of preparing a sponge synthesized by a biological basisocyanate, including the following processing steps:
[0065] S1. After mixing the polyether polyol and the bio-group diisocyanate TDI is drawn into each reservoir, and the temperature of the reservoise is 23 ± 2 ° C, the humidity is <50%;
[0066] S2. Then prepare the kraft paper and the side plastic film are placed in the conveyor belt, and adjust the height of the discharge port of the mixed head, 2cm above the kraft paper;
[0067] S3. Plate the silicone surface activator, amine catalyst, dichloromethane, polyether polyol, and color paste are induced into the metering pump, and into the mixed head after metering the pump, and tin, water and biotroate toluene The isocyanate is introduced into the mixer head in ratio, and the rotational speed of the mixing head is 4000 rpm, and the discharge port begins to be injection molded to kraft paper, and then control the running speed of the conveyor belt at 3 m / min;
[0068] S4. Cut the injection molded sponge block into the required specification, then transport to the warehouse storage, and wait for the sponge to be ripe in the warehouse, it gave a sponge synthesized from the biological toluene diisocyanate.
[0069] The above bio-based TDI is made of toluene refreding in the organism to nitric acid, hydrogen, carbon monoxide and oxygen;
[0070] Preferably, the bio-based TDI is made of toluene refreding in the rubber to nitric acid, hydrogen, carbon monoxide and oxygen;
[0071] Formulation method Figure one Indicated.
[0072] A sponge mattress synthesized from a biological basin, including an outer casing 1, and an inner portion of the outer casing 1 is provided, and the inner bottom end of the inner casing 2 is provided with a support layer 5 containing the bottom bio-group diisocyanate synthesis ordinary sponge. 5, The upper end of the support layer 5 containing the biological toluene diisocyanate synthesis common sponge is provided with a second top-layer bio-group diisocyanate synthesized slow rebound memory wool layer 4, a second top-layer bio-benzene diisocyanate synthesis slow rebound memory The upper side of the cotton layer 4 is optionally increased or does not increase the slow rebound memory wool layer 3 provided with the first topic bio-group diisocyanate synthesis.
[0073] The slow rebound memory wool layer 3 and the second top-layer bio-group diisocar layer 3 and the second topic bio-benzene diisocyanate synthesis were synthesized by mixing the isocyanate mixture of bio-group diisocyanate. Slow rebound sponge, the toluene group in the bio-group diisocyanate contains a biotech carbon element; the bottom portion containing a common sponge of the biophenylene diisocyanate synthesis The normal sponge containing toluene isocyanate is used, wherein The toluene diisocyanate is synthesized from toluene containing bio-carbon elements.
[0074] Sponge mattresses prepared by biotrial isocyanate include thin pads and thick pads, wherein the height of the thin pad is <10 cm, length> 130cm, width> 70cm, and uses one or more of the first examples of the first, second, and three types of sponges. Bonding with glue, can also be combined with a high degree of <4cm spring, latex, coconut brown or animal hair as an accessories, thick pads> 10cm, length> 130cm, width> 70cm, use Examples 1, 2, 3 3 Two or more of the particles in a sponge, bonded to glue, the sponge of the examples as the bottom layer of the mattress, the sponge of the second and Example 3 as the top layer of the mattress, or can be added to the separate bag spring spring , Felt, latex, coconut brown or animal hair is an excipient, such as by a separate bag spring, together with the bottom of the mattress.
