Problems solved by technology

However, because nano-silver is only simply mixed in the latex mattress and evenly distributed in the mattress, the concentration of nano-silver on the surface of the mattress is consistent with that inside; but in actual use, bacteria are usually distributed on the surface of latex mattresses in large numbers , and the nano-silver on the surface of the mattress will gradually lose during use as people clean the mattress. Therefore, the concentration of nano-silver on the surface of the nano-silver antibacterial latex mattress made by this method decreases faster during use. , leading to a shorter duration of antibacterial effect, it is difficult to achieve long-term antibacterial effect
In addition, if the content of nano-silver is increased, a large amount of nano-silver ions in the early stage of use will easily release excessive silver ions during the dissolution or oxidation process, which will cause cytotoxicity and affect the health of users

preparation example Construction

[0029] The invention provides a kind of preparation method of long-acting antibacterial latex mattress, and its preparation process is as follows figure 1 described, including the following steps:

[0030] S1. Preparation of antibacterial agent: preparation of nanometer mesoporous TiO 2 , and the nanomesoporous TiO 2 Mix with silver nitrate solution according to the preset molar ratio to prepare silver-loaded nano-mesoporous TiO 2 ; For the silver-loaded nanometer mesoporous TiO 2 Carry out silanization treatment, and the silver-loaded nanometer mesoporous TiO after treatment 2 Mix with polyethyleneimine, disperse in methanol, and perform tertiary amination reaction; after the reaction, mix the product with hexadecane bromide and disperse in methanol for quaternization reaction; after the reaction, wash the product Dry to obtain quaternized silver-loaded nano-mesoporous TiO 2 , and then disperse it in deionized water to obtain an antibacterial agent;

[0031] S2. Prepara...

Embodiment 1

[0044] see figure 1 , the present embodiment provides a kind of preparation method of long-acting antibacterial latex mattress, comprises the steps:

[0045] S1, preparation of antibacterial agent

[0046] Preparation of Nano Mesoporous TiO 2 , and the nanomesoporous TiO 2 Mix with silver nitrate solution at a molar ratio of 1:3 to prepare silver-loaded nano-mesoporous TiO 2 ; The silver-loaded nanometer mesoporous TiO 2 Mix with ethanol and γ-aminopropyltriethoxysilane at a mass volume ratio of 1g:40mL:0.5mL, stir and react at 50°C for 12h, centrifuge the product, wash with absolute ethanol, and store at 50°C After drying under vacuum, the silanized silver-loaded nano-mesoporous TiO 2 ; Then the silver-loaded nanometer mesoporous TiO of described silanization 2 Mix with polyethyleneimine at a mass ratio of 2:1, disperse in methanol, and react at 3°C ​​for 7 hours for tertiary amination reaction; after the reaction, mix the product with hexadecane bromide at a mass ratio...

Embodiment 2～5

[0059] Embodiment 2~5 provides a kind of preparation method of long-acting antibacterial latex mattress, compared with embodiment 1, the difference is that the reaction conditions of tertiary amination reaction and quaternization reaction in the step S1 are changed, each implementation The corresponding reaction conditions are shown in Table 2.

[0060] The reaction conditions of tertiary amination reaction and quaternization reaction in step S1 among the embodiment 2~5 of table 2

[0061]

[0062] The antibacterial properties of the long-acting antibacterial latex mattresses prepared in Examples 2 to 5 were tested under different time periods, and the results are shown in Table 3.

[0063] The antibacterial rate of the long-acting antibacterial latex mattress that table 3 embodiment 2~5 makes in different time periods

[0064]

[0065] As can be seen from Table 3, changing the relevant conditions of tertiary amination reaction and quaternization reaction has certain in...

Abstract

The invention discloses a long-acting antibacterial latex mattress and a preparation method thereof, by loading nano-silver on nano-mesoporous TiO 2 inside the pores, and on the nano-TiO 2 Perform quaternization to prepare an antibacterial agent with excellent antibacterial effect and slow-release effect; and use the prepared antibacterial agent in the two processes of preparation and finishing of latex mattresses to obtain latex with long-lasting antibacterial effect Mattress. Through the above method, the present invention can make nano-silver loaded on nano-mesoporous TiO 2 The holes can play a slow-release effect and ensure the continuous and stable output of antibacterial ingredients; the present invention can also make nano-mesoporous TiO 2 It has the antibacterial effect of quaternary ammonium salt, thereby effectively improving the antibacterial effect of antibacterial agents. At the same time, by finishing the latex mattress, the present invention can not only load more antibacterial ingredients on the surface of the mattress, improve the antibacterial effect; but also reduce the antibacterial ingredients on the surface of the mattress, prolong the time of antibacterial action, thereby achieving long-acting antibacterial Effect.

Description

technical field [0001] The invention relates to the technical field of latex mattresses, in particular to a long-acting antibacterial latex mattress and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, there are higher requirements for the quality of life and daily necessities. As an indispensable article of daily use in people's daily life, mattresses are closely related to people's sleep and health, so they have received extensive attention. Existing mattresses mainly include palm mattresses, spring mattresses, sponge mattresses and latex mattresses. Among them, latex mattresses are widely accepted for their soft touch, good air permeability, hygroscopicity and high elasticity. Consumer favorite. However, ordinary latex mattresses do not have antibacterial effects. During use, bacteria are easy to breed and affect people's health. Therefore, it is of great significance to conduct antibacteria...
