Problems solved by technology

[0003] However, because the existing latex products are made of pure natural latex, the latex products are easily weathered with the passage of time, and then the surface of the product will be damaged, which seriously affects the quality of the product
In addition, since the existing latex products are made of pure natural latex, their cost is relatively high

preparation example Construction

[0037] The present invention also provides a method for preparing milk cotton, the milk cotton is the milk cotton as described in any of the above embodiments, please refer to figure 1 , the preparation method of described milk cotton comprises the steps:

[0038] S110: Stir and mix the polyether polyol, silicone oil, amine catalyst, tin catalyst, crosslinking agent and water for the first time to obtain a first mixture;

[0039] In this embodiment, the temperature of the first stirring and mixing operation is 18°C-26°C. In this way, the various components can be mixed well.

[0040] In one of the embodiments, the step 110 is specifically: put polyether polyol, silicone oil, amine catalyst, tin catalyst, crosslinking agent and water into the stirred tank for the first stirring and mixing operation to obtain the first mixture ; Thus, by putting polyether polyol, silicone oil, amine catalyst, tin catalyst, crosslinking agent and water into the stirring tank, the stirring and m...

Embodiment 1

[0049] A kind of milk cotton comprises each component of following mass parts:

[0050]

[0051] Among them, the crosslinking agent is zinc chloride, the tin catalyst is stannous octoate, and the amine catalyst is tetramethylethylenediamine, wherein tetramethylethylenediamine is an aqueous solution with a concentration of 2%, that is, the amine catalyst is tetramethylethylenediamine. An aqueous solution of ethylenediamine at a concentration of 2%. Water is deionized water.

[0052] Milk cotton preparation method is as follows:

[0053] Put polyether polyol, silicone oil, amine catalyst, tin catalyst, crosslinking agent and water into the stirred tank for the first stirring and mixing operation to obtain the first mixture; during the first stirring and mixing operation, control the temperature of the stirring tank The temperature is 22 degrees Celsius, the stirring speed is 550 rpm, and the stirring time is 3 minutes.

[0054] Add isocyanate to the first mixture to carry ...

Embodiment 2

[0057] The difference from Example 1 is that the temperature of the first stirring and mixing operation is 17 degrees Celsius, and the temperature of the second stirring and mixing operation is 17 degrees Celsius.

Abstract

Disclosed are a latex-like cotton and a preparation method thereof. The latex-like cotton is composed of, by weight part, 65-68 parts of polyether polyols, 28-31 parts of isocyanate, 0.1-0.4 part of silicone oil, 0.1-0.14 part of amine catalyst, 0.02-0.06 part of tin catalyst, 1.2-1.5 parts of crosslinking agent and 2-2.5 parts of water. The latex-like cotton made of the components above can achieve good resilience and have a good touch feeling like latex. Meanwhile, due to the fact of containing no natural latex materials, the latex-like cotton is less prone to weathering, long in service life and comparatively low in cost.

Description

technical field [0001] The invention relates to the technical field of materials, in particular to milk cotton and a preparation method thereof. Background technique [0002] Sponge is a porous material with good touch and elasticity, and has been widely used in various industries. Latex products, also called latex sponge, as a new application material in recent years, have breathable honeycomb pores, high elasticity, shock absorption, resistance to compression fatigue, good load-carrying capacity, comfort and durability, etc. Compared with the existing traditional sponge, latex products have better touch and resilience, so they are more popular among consumers. [0003] However, the existing latex products are made of pure natural latex. As the use time goes on, the latex products are very easy to weather, and then there is a problem of product surface loss, which seriously affects product quality. In addition, since the existing latex products are made of pure natural la...
