Problems solved by technology

In such a silk latex quilt, silk and latex hinder each other, and the advantages of the two cannot be fully utilized; and silk and latex are essentially a two-phase separation system, which leads to poor mechanical properties of the quilt and is completely unsuitable for machine washing, resulting in The actual use effect of this kind of silk latex quilt is very poor
In addition, the silk latex quilt disclosed in the prior art must use complete and fresh silk, and a large amount of silk debris produced during the reeling process cannot be effectively utilized, which also causes a waste of resources.

preparation example

[0031] Mix and wash the silk and silk leftovers according to the weight ratio of 1:1. Get 100g of silk raw material, drop into 150mL of .5wt.% sodium carbonate aqueous solution, stir at 110°C for 25min, filter to remove insolubles, put the filtrate into 1.55L of 40wt.% calcium chloride:ethanol=1:2 In the mixed solution of volume ratio, it was processed at 50° C. for 60 minutes overtime, and filtered to obtain the fibroin filtrate from which sericin was removed.

[0032] Concentrate the fibroin filtrate under reduced pressure until the fibroin content is 7.5wt.%, then use hydrochloric acid to adjust the pH of the system to 7.5, add 32g of alkaline protease, stir at 55°C for 120min, put in excess activated carbon, and stir again , filtered after standing to obtain silk hydrolyzate.

Embodiment 1

[0034] 100kg of natural latex concentrate (solid content ≥ 60%), 15kg of silk hydrolyzate prepared in Example 1, 0.2kg of OP-10, 1kg of sulfur, and 1.2kg of vulcanization accelerator M are dropped into the mixing kettle, mixed evenly, and then dropped into The amount of anti-aging agent, pigment and inorganic filler is appropriate, and the mixed material liquid is cast into a flat cuboid mold, sent to an oven for vulcanization at 120°C for 8 minutes, and the latex silk quilt is obtained after demoulding.

Embodiment 2

[0036] Add water to the redispersible natural latex powder to prepare natural latex liquid with a solid content of 75wt.%. Take 100kg and mix it with 20kg of the silk hydrolyzate prepared in Example 1. When mixing, add 0.2kg of Span-60.2kg, 1.2kg of sulfur, and two Add 1.1kg of zinc ethyl dithiocarbamate, and then put in appropriate amount of anti-aging agent, pigment and antibacterial agent, and mix well to form the impregnation solution.

[0037] Soak the cotton cloth in the aforementioned soaking liquid, stack 5 layers of soaked cotton cloth, heat-press at 80°C for 20s, cut the edge, send it to a flat vulcanizer, and heat-press at 95°C for 30 minutes to obtain a latex silk quilt.

Abstract

The invention belongs to the field of beddings, specifically relates to a silk latex quilt, and further relates to a preparation method of the silk latex quilt. The silk latex quilt is prepared from the following raw materials in parts by weight: 100 parts of natural latex solution, 15 to 20 parts of silk hydrolysate, 0.1 to 0.3 part of surfactant, 1.0 to 1.5 parts of sulfur and 1.0 to 1.5 parts of vulcanization accelerator. According to the improved silk latex quilt provided by the invention, the silk latex quilt is capable of comprehensively utilizing the advantages of latex and silk, and homogeneous-phase combination of the silk and the latex can be achieved by utilizing the silk hydrolysate, so that the mechanical property of the silk latex quilt is further improved, namely, the silk latex quilt is more suitable for daily washing, storage and use.

Description

technical field [0001] The invention belongs to the field of bedding, and in particular relates to a silk latex quilt, and further relates to a preparation method thereof. Background technique [0002] There are various types of separate latex quilts and silk quilts on the market, each with its own advantages and disadvantages. The silk quilt is made of high-quality silk, and with its novel fiber structure, the water vapor can circulate freely. In addition, the unique air permeability and moisture permeability of silk itself make the silk quilt feel smoother, cool but not warm, warm but not dry, known as " The reputation of "the second skin of the human body" and "fiber queen". Latex has the effect of anti-mite, anti-bacteria and breathable. Because the oak protein in latex can inhibit the latent germs and allergens, it meets the requirements of environmental protection, can inhibit the breeding of germs and mites, and has no static electricity. Thousands of exhaust holes ...
