Technical Field
The invention belongs to the technical field of latex foam, and particularly relates to aerogel latex foam, and a preparation method and application thereof.
Background
Since the 20 th century the direct manufacture of latex articles from natural latex, the production of latex articles has evolved into an important part of the rubber industry. The world rubber latex consumption in the 80 s is about 10% of the total consumption of rubber.
The production process of the latex product is completely different from the processing of the dry rubber, and huge heavy machinery and a plurality of procedures are not needed, thereby providing conditions for large-scale popularization and use. Latex products are increasingly favored because of the characteristics of natural raw materials, high air permeability, ultra-silence, high rebound resilience and the like, and are widely used for manufacturing mattresses, pillows, soles, gloves, toys, rubber tubes and the like. The natural latex products have the defects of easy oxidation, high price, sensitization and the like after contacting ultraviolet rays. The synthesized latex product contains butadiene and styrene, and can release benzene and formaldehyde gas at a certain temperature, thus having great influence on human health. SiO (SiO) 2 The aerogel is an inorganic nano porous material, and is applied to the foaming process of natural latex, and the prepared latex product has the characteristics of antioxidation, low price and no harm to human bodies, and can greatly reduce the price of the natural latex product, thereby promoting the popularization of the natural latex product in daily life.

The antibacterial agent is selected from KP-F25, flos Caryophylli essential oil, lavender essential oil, herba Rosmarini officinalis essential oil, herba Salvia officinalis essential oil, thyme essential oil, silver ion antibacterial agent, copper ion antibacterial agent or zinc ion antibacterial agent, etc.
The invention also provides a preparation method of the aerogel latex foam, which comprises the following steps:
1) Uniformly stirring 90-100 parts by weight of concentrated latex and 3-20 parts by weight of aerogel filler, and sequentially adding 1-2 parts by weight of accelerator, 1-3 parts by weight of vulcanizing agent, 1-2 parts by weight of anti-aging agent and 3-5 parts by weight of foaming agent or further adding antibacterial agent under uniform stirring, wherein the concentrated latex is concentrated natural latex or concentrated synthetic latex, and the amount of latex is 54-70 parts by weight, namely, the solid content of the concentrated latex is 60-70 wt%;
2) Adding 1-3 parts by weight of an activating agent under uniform stirring, and foaming at 140-160 ℃;
3) After foaming, adding 1-3 parts by weight of gelling agent and 1-3 parts by weight of vulcanizing agent for solidification and vulcanization;
4) And dehydrating and drying to obtain the aerogel latex foam. 1 to 5 parts by weight of residual water after dehydration and drying.
The aerogel filler is SiO 2 Aerogel, or SiO with solid content of 5-20wt% 2 Aerogel slurry is used as raw material, siO therein 2 The aerogel comprises 3-20 parts by weight.
Specifically, the weight portion of the concentrated latex is 90-95 portions, and the solid content of the concentrated latex is 63-65 wt%.
The invention also provides application of the aerogel latex foam, which is used for manufacturing: mattress, pillow core, sole, glove, toy or rubber tube. The invention has the beneficial effects that:
1、SiO 2 the aerogel has low heat conductivity coefficient and low density, and can be added into the latex foam to improve the heat insulation performance of the latex foam. Thus being particularly suitable for manufacturing mattresses, pillow cores, soles, gloves and rubber tubes.
2、SiO 2 Aerogel belongs to inorganic materials, is incombustible in air, and can improve the fireproof performance of latex foam when added into the latex foam. Thus being particularly suitable for manufacturing mattresses, pillow cores, soles, gloves, toys or rubber tubes.
3. SiO is added into the latex foam 2 Aerogel, its tensile strength reinforcing, compression resilience improves. And the bubbles in the latex foam become more uniform due to the nucleation effect of the aerogel, a tableThe surface folds and the mesoporous structure form slits, and the energy barrier required by the nucleation of bubbles on the surface of the foam is reduced, so that the average pore diameter of the foam is reduced. Thus being particularly suitable for manufacturing mattresses, pillow cores and soles.
4. The natural latex is added into the natural latex, so that the production cost of the natural latex product can be reduced, the oxidation resistance of the natural latex product under ultraviolet irradiation can be improved, and the service life of the natural latex product can be prolonged. Thus being particularly suitable for manufacturing rubber pipes.
