Problems solved by technology

[0002] Vegetative blanket is a kind of geotechnical material that has been widely used in the field of ecological protection and restoration. It is a water and soil conservation product with a certain thickness that combines plant fibers or synthetic fibers of certain specifications with seed vegetation belts. However, the existing There are defects in the material structure, processing method and plant species selection of the vegetation blanket, especially for the application of the underwater vegetation blanket. The plant seeds in the planting blanket also have disadvantages that seriously affect the ecological restoration effect, such as the low germination rate caused by the defects of the existing processing technology, and the seeds are prone to mildew during storage.

Embodiment

[0022] Take 70 parts of polylactic acid, 20 parts of limonene, 8 parts of anhydrous glycerin, and 2 parts of Tween-80. First, homogenize the polylactic acid, limonene, and Tween-80 at room temperature and at a speed of 20,000 rpm for 3 minutes. chemical treatment, and wait for the air bubbles to be eliminated. Then add anhydrous glycerin and stir for 30 minutes to prepare bioadhesive.

[0023] Subsequently, the skeleton layer and the protective layer are bonded by hot-melt method, and the concentration of 30% bio-adhesive is coated below the protective layer, and the bio-adhesive is diluted with limonene, and then the seeds are treated with a certain amount of Mix 5 g / m2 of sodium polyglutamate, spread it on the bio-adhesive, then cover the tissue paper layer on the material covered with plant seeds, and press lightly with a soft roller. The flat vacuum negative pressure equipment is used to absorb the layers of the material, and complete the glue at room temperature without ...

Abstract

The invention relates to the field of materials for phytoremediation in bank slopes and wading areas, in particular to a plant growing blanket capable of resisting current scour and a preparation method thereof. The plant growing blanket capable of resisting the current scour comprises a skeleton layer, a protecting layer, a plant growth regulating agent layer and a tissue paper layer. The plant growing blanket capable of resisting the current scour is characterized in that the protecting layer, the plant growth regulating agent layer and the tissue paper layer are sequentially arranged underthe skeleton layer from top to bottom, wherein the skeleton layer is a gridding-shaped fabric formed by interlacing warp yarn and weft yarn; and the warp yarn is composed of first warp yarn, second warp yarn, third warp yarn, fourth warp yarn, fifth warp yarn, sixth warp yarn, seventh warp yarn and eighth warp yarn, and the weft yarn is composed of first weft yarn, second weft yarn, third weft yarn and fourth weft yarn. According to the plant growing blanket capable of resisting the current scour and the preparation method thereof, compared with the prior art, the plant growing blanket is bonded through hot melting and ecological adhesives, an integrated carrier which can resist large water flow scour and bear plant seeds, and does not destroy the plant growing environment, and used for implantation, germinating and growing of plants is formed in a combination mode; the structure is simple, the biocompatibility of materials is high, the engineering implementation is convenient, contained plant seeds can be customized according to engineering areas, so that the adaptability is high.
