Embodiment 1

[0029] Embodiment one: a kind of preparation method of silk-natural latex composite foaming sponge material comprises the following steps:

[0030] Step 101: Preparation of silk suspension

[0031] After the silkworm cocoons are decontaminated and impurity removed, they are cut into pieces with a machine to obtain silk segments with a length of 0.5 cm, and then the silk segments are put into 20 times the weight of deionized water, boiled at 60°C for 20 minutes, cooled and precipitated, and removed. Part of the supernatant was removed, and after ultrasonic dispersion treatment, a mixed suspension of sericin and silk fibroin was obtained. It was determined that sericin accounted for 8% of the total weight of the suspension, and silk fibroin accounted for 8% of the total weight of the suspension. The percentage is 35%.

[0032] Step 102: Preparation of mature latex

[0033] Select the concentrated latex from Hevea brasiliensis, in parts by mass, mix 1.0 parts of potassium hydro...

Embodiment 2

[0038] Embodiment two: a kind of preparation method of silk-natural latex composite foaming sponge material comprises the following steps:

[0039] Step 101: Preparation of silk suspension

[0040] After the silkworm cocoon is decontaminated and impurity removed, cut it into pieces with a machine to obtain a silk segment with a length of 0.5cm, and then put the silk segment into 30 times the temperature of 65°C for 30 minutes under deionized water, then precipitate it, and remove the supernatant A mixed suspension of sericin and silk fibroin is obtained through ultrasonic dispersion treatment. It is determined that sericin accounts for 5% of the total weight of the suspension, and silk fibroin accounts for 30% of the total weight of the suspension.

[0041] Step 102: Preparation of mature latex

[0042] Select the concentrated latex from Hevea brasiliensis for use, in parts by mass, mix 1.5 parts of potassium hydroxide with a concentration of 10% and 167 parts of concentrated...

Embodiment 3

[0047] Embodiment three: a kind of preparation method of silk-natural latex composite foaming sponge material comprises the following steps:

[0048] Step 101: Preparation of silk suspension

[0049] After the silkworm cocoon is decontaminated and impurity removed, cut it into pieces with a machine to obtain a silk segment with a length of 1.0 cm, and then put the silk segment into 20 times the temperature of 60 ℃ deionized water and cook for 30 minutes, then precipitate and remove the supernatant , the silk fibroin suspension is obtained through ultrasonic dispersion treatment, wherein the weight percentage of the sericin in the suspension is 4.0%, and the content of the silk fibroin is 25%.

[0050] Step 102: Preparation of mature latex

[0051] Select the concentrated latex from Hevea brasiliensis, in parts by mass, mix 2.0 parts of potassium hydroxide with 170 parts of concentrated natural latex with a dry rubber content of 60%, add 2.5 parts of sulfur and 2.5 parts of ac...

Abstract

The invention discloses a preparation method of a silk-natural latex composite foam sponge material. The preparation method includes the steps of 101, partially removing latex from a silk section andperforming dispersing treatment to obtain a suspension, wherein sericin content in the suspension is 4%-8%, and silk fibroin is 25%-35%; 102, evenly mixing a latex stabilizer with concentrated naturallatex by adding a vulcanizing agent, a promoter and an anti-aging agent with even stirring to obtain cured latex after standing and curing; 103, adding 4.0-8.0 parts of the suspension to pretreated cured latex with even mixing, adding a first coagulant, a foam stabilizer and a filler with even stirring, adding a foaming agent with mechanical stirring, and then adding a second coagulant and an active agent with even stirring to obtain a foaming precursor; 104, subjecting the foaming precursor to curing and forming to obtain the silk-natural latex composite foam sponge material. The preparationmethod is simple in process and low in cost, and the prepared composite material is good in resilience and mechanical property and is a superior bedding material.

Description

technical field [0001] The invention relates to the technical field of natural latex products, in particular to a silk-natural latex composite foaming sponge material and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards and the increasing awareness of health, latex pillows, latex mattresses and other products are all the rage. Latex pillows / mattresses are made of pure natural latex juice. No harmful substances are added during the production process. They are naturally environmentally friendly and pollution-free. They have a certain anti-mite and anti-bacterial ability. The heat generated, its unique soft touch and high elasticity of latex can conform to the contours of the body, relying on the human spine, making the spine into the best straight line without any burden, so as to achieve a healthy, stable and comfortable sleep, so it has become the most popular bedding in recent years The filling ...
