Embodiment 1

[0033] 1. Obtain collagen fibers from wet blue hide waste.

[0034] (1) Cut the waste wetblue hide into strips of 2×5 cm and soak them in a weakly alkaline aqueous solution containing sodium hydroxide. The percentages are respectively: sodium hydroxide is 0.1%, acetamide is 0.2%, glycerin is 0.1%, fatty alcohol polyoxyethylene ether is 0.5%, and the immersion time of this wet blue leather waste in this weak alkaline aqueous solution is 30 hours;

[0035] (2) drying the soaked wet blue hide waste with a spin dryer, and the moisture content of the dried wet blue hide waste reaches 70%;

[0036] (3) Send the dried wet blue hide waste into a licker-in roller opener for opening and tearing to obtain collagen fibers, the fiber pile length of which is 5 mm, and the fiber bundle linear density is 1.1 dtex;

[0037] (4) Send the collagen fibers into an antiseptic solution for antiseptic treatment. The preservative used in the antiseptic solution is a mixture of sodium sorbate and ethyl...

Abstract

The invention discloses an environment-friendly building material and a preparation method thereof, and relates to the field of new building materials. The middle layer of the environment-friendly building material is a collagen fiber net, and the upper and lower layers are woven fabrics, and the collagen fiber is extracted from wet blue leather waste. The preparation method of the collagen fiber thermal insulation material provided by the invention, by simplifying and shortening the extraction of the collagen fiber in the wet blue hide waste material and the network reinforcement process, prepares the collagen fiber thermal insulation material with good use strength, and achieves the goal of using the wet blue hide waste material. The low-cost and large-scale utilization of collagen fibers in wet blue hide waste, on the one hand, provides a good way for tanning companies to reduce the burden of waste and turn waste into treasure; It has many advantages such as moisture and breathability, light weight, warm in winter and cool in summer, and flame retardant. It is easy to install on site. It is an environmentally friendly building material and provides an ideal choice for modern buildings that pursue environmental protection and comfort.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to an environment-friendly building material and a preparation method thereof. Background technique [0002] my country is a large leather-making country. According to statistics in 2011, there are more than 850 leather-making enterprises above designated size in my country, with more than 200,000 employees, a total industrial output value of more than 120 billion yuan, and an output of more than 700 million square meters of finished leather, accounting for 20% of the world's total finished leather production. However, my country's tanning industry has always adopted the traditional wet-blue leather process. Enterprises produce more than 1.4 million tons of wet-blue leather waste every year, accounting for almost one-half of the world's total. Now the main methods of processing wet-blue leather waste are incineration and The method of landfill, but both all can have persistent d...
