Description

An antistatic natural latex pillow

technical field

The invention relates to the field of latex sponges, in particular to an antistatic natural latex pillow.

Background technique

In the field of latex sponges, the static electricity of natural latex sponges not only affects the user experience of subsequent latex milk products, but also cannot open the market for anti-static clothing for special operations, and often causes vicious combustion and explosions in some factory operating places due to static electricity hazards. ACCIDENT. Therefore, it is necessary to improve the antistatic performance of latex products. As a latex pillow, because the latex sponge itself is non-conductive and has static electricity, this characteristic affects the daily use of latex pillows, and cannot meet people's ever-increasing pursuit of quality of life.

Contents of the invention

In view of the above problems, the present invention provides a kind of anti-static natural latex pillow which is easy to process, reliably prevents static electricity and provides high quality.

The technical scheme of the present invention is: include graphene-modified latex sponge thin layer as the outer layer of the pillow core (that is, the surface where the pillow contacts the head and neck), the inside of the pillow center is a carbon fiber reinforced latex sponge core, and the bottom of the pillow is Metal fiber woven cloth; they are bonded together by natural glue, an environmentally friendly material.

The preparation method of described latex sponge core is:

Mix natural latex, sulfur, vulcanization accelerator, zinc oxide, potassium ricinoleate, potassium vegetable oleate, potassium hydroxide, carbon fiber, and 2-hydroxycyclodextrin with a high-speed disperser to form a mixed solution, and keep the temperature in a water bath at 28°C Mature under conditions for 8-12 hours, then mix sodium fluorosilicate and foam it through a high-speed foaming machine, pour it into a pillow mold, vulcanize in a steamer at 100°C for 30 minutes, and then wash and dehydrate, microwave dry and electric blast dry.

It also includes shellac resin sodium salt and halloysite nanotubes, the shellac resin sodium salt is formulated into a solution of shellac resin sodium salt with a concentration of 4wt% to 8wt% (that is, shellac resin sodium salt is dissolved in water), and the The halloysite nanotubes are added to the sodium salt solution of lac resin to form a dispersion of halloysite nanotubes with a concentration of 10 wt% to 25wt%; a high-shear emulsifier is used for emulsification to obtain stably dispersed halloysite nanotubes -The shellac resin sodium salt dispersion is ready for use; wherein, the rotating speed of the high shear machine is 10000rpm, and the shearing time is 15min.

The weight part of the halloysite nanotube-lac resin sodium salt dispersion is 3-10 parts, which is added into the mixed solution and stirred evenly;

In this way, the halloysite nanotube-lac resin sodium salt dispersion is introduced into the mixed solution for the first time before foaming,

The halloysite nanotubes are emulsified and dispersed by polyhydroxyl oligomer shellac resin sodium salt, which has a Gemini-like surfactant structure, which can form aggregates to coat halloysite nanotubes. The dispersibility of the halloysite nanotubes is improved; at the same time, due to the presence of hydroxyl groups on the surface of the halloysite nanotubes, hydrogen bonds can be formed with the sodium salt of the shellac resin, so that the dispersion in the natural latex is improved.

The addition of sodium fluorosilicate during the foaming process promotes the transformation of the amphiphilic molecule shellac resin sodium salt into shellac resin, and then assembles into nanovesicles. Based on its special asymmetric Gemini-like surfactant structure, the formation of The hydrophobic chains between the vesicles are prone to "bonding" to form a three-dimensional hydrogel, and the gel-wrapped halloysite nanotubes are filled in the natural latex sponge to form an elastic support, which has a greater support for the cells of the natural latex sponge , The ability of the foam to restore its original shape is strong, so that the compression permanent deformation is small.
