Example 2
The manufacturing method of the composite formaldehyde-removing deodorizing antibacterial multifunctional latex sponge comprises the following preparation steps:
(1) Preparation of modified polysiloxane reinforcing agent: tetramethyl cyclotetrasiloxane (D4) H ) Vinyl-terminated polydimethylsiloxane (VPS-2000) having an average molecular weight of 2000 and allyl polyoxyethylene ether (APER-2400) at a molar ratio of D4 H : APER-2400: VPS-1500=1:1.6:1.2 is added into a mixed solvent of ethanol and cyclohexane, stirred and dissolved uniformly, then the temperature is raised to 80-90 ℃, a chloroplatinic acid isopropanol solution catalyst is added for stirring and reacting for 3 hours, and after the reaction is finished, the solvent and low-boiling-point substances are removed in vacuum, so that the modified polysiloxane reinforcing agent is obtained.
(2) Preparation of a multifunctional latex sponge: adding the modified polysiloxane reinforcing agent obtained in the step (1), inorganic aldehyde-removing deodorizing powder material (the mixture of nano porous carbon with the particle size smaller than 1 mu m and nano photocatalyst powder according to the mass ratio of 2:1) and inorganic antibacterial mildew-proof material (the mixture of nano silver oxide powder and nano zinc oxide powder according to the mass ratio of 1:1) into natural latex foam liquid, and stirring and mixing uniformly, wherein the addition amount of the modified polysiloxane reinforcing agent is 2% of the solid content of the foam liquid of the polyurethane foam, and the addition amounts of the inorganic aldehyde-removing deodorizing powder material and the inorganic antibacterial mildew-proof material are 3% and 2% of the solid content of the foam liquid of the polyurethane foam respectively. Then foaming and molding to obtain the composite formaldehyde-removing deodorizing antibacterial multifunctional latex foaming sponge. The natural latex sponge foaming liquid comprises 97% of natural latex liquid, 2% of surfactant and 1% of vulcanizing agent.
The test result of the performance of the composite formaldehyde-removing deodorizing antibacterial multifunctional latex sponge obtained in the embodiment shows that the formaldehyde-removing rate is 89%, the deodorizing rate is 80%, the antibacterial rate is 99% (refer to GB/T20944.3-2008 oscillation method; the test bacterium is staphylococcus aureus), and the mildew-proof grade is 0 (GB/T24346-2009). The softness test result was 5.0 minutes. The mechanical strength performance test result shows that the tensile strength is 247kPa and the elongation at break is 236%. The aging resistance test result showed that the strength retention was 95.1% and the elongation retention was 94.9%. The test result of the performance of the formaldehyde-removing deodorizing antibacterial multifunctional latex sponge without the modified polysiloxane reinforcing agent shows that the formaldehyde-removing rate is 90%, the deodorizing rate is 81%, the antibacterial rate is 99% and the mildew-proof grade is 0.

Comparative example 1
In this comparative example, D4 is compared with example 1 H : APER-800: VPS-1000=2:6:1, the remainder being the same.
The softness test result of the composite formaldehyde-removing deodorizing multifunctional polyurethane foaming sponge obtained in the comparative example is 3.8 minutes. The mechanical strength performance test result shows that the tensile strength is 178kPa and the elongation at break is 120%. The aging resistance test result showed a strength retention of 75.8% and an elongation retention of 76.7%.
As can be seen from the comparison of the present comparative example with example 1, too little long-chain polysiloxane segment in the modified polysiloxane reinforcing agent has limited effect of improving the softness, mechanical strength and aging resistance of the sponge material.
Comparative example 2
In this comparative example, D4 is compared with example 1 H : APER-800: VPS-1000=1:0.8:1.6, the remainder being the same. The obtained modified polysiloxane reinforcing agent cannot be dissolved and dispersed in an aqueous solution system.
The softness test result of the composite formaldehyde-removing deodorizing multifunctional polyurethane foaming sponge obtained in the comparative example is 4.0 minutes. The mechanical strength performance test result shows that the tensile strength is 192kPa, and the elongation at break is 127%. The aging resistance test result showed that the strength retention was 81.3% and the elongation retention was 83.5%.
As can be seen from the comparison of the present comparative example with example 1, too little long chain polyether is added and too much VPS is added during the preparation of the modified polysiloxane reinforcing agent, resulting in a decrease in the reinforcing effect. The reason for this is that too little amount of long-chain polyether is added and too much amount of VPS is added, which results in the presence of partial crosslinking of the modified polysiloxane reinforcing agent, and the hydrophilicity is reduced, the solubility and dispersibility thereof in the sponge foaming liquid is reduced, and the modifying effect is deteriorated.
Comparative example 3
This comparative example was compared to example 1, using a conventional commercially available water-soluble long chain polyether modified silicone oil instead of the modified polysiloxane enhancer, the remainder being the same.
The softness test result of the composite formaldehyde-removing deodorizing multifunctional polyurethane foaming sponge obtained in the comparative example is 3.8 minutes. The mechanical strength performance test result shows that the tensile strength is 185kPa and the elongation at break is 122%. The aging resistance test result showed a strength retention of 76.2% and an elongation retention of 77.9%.
As can be seen from the comparison of the present comparative example with example 1, the substitution of the modified polysiloxane reinforcing agent of the present invention with the conventional water-soluble polyether-modified silicone oil containing no cyclic structure resulted in a decrease in the reinforcing effect. The reason is that the polyether chains of the common polyether modified silicone oil are unevenly distributed, long-chain polysiloxane chains of the common polyether modified silicone oil cannot be effectively stretched in a sponge base material, and the polysiloxane chains have obvious aggregation and winding tendency, so that the reinforcing effect is reduced.

The manufacturing method of the composite formaldehyde-removing multifunctional sponge chip comprises the following preparation steps:
