RU2473597C1 - Mulching composition - Google Patents

Abstract

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry of synthetic substances - polymer substances in a mixture with organic and natural substances, for example, for urban and agricultural purposes, or to compositions for mulching different types of soil, lawn and parking areas. The mulching composition is characterised by that it contains lignosulphonate, carbamide, NA-carboxymethyl cellulose, potassium chloride and, as natural additives, Andreaeopsida moss and Pinus koraiensis pine needles, and water in the following ratios, wt %: lignosulphonate 0.1-0.4; carbamide 0.2-0.6; NA-carboxymethyl cellulose 0.3-0.4; potassium chloride 1-3; Andreaeopsida moss 10-15; Pinus koraiensis pine needles 8-9; water - the balance.

EFFECT: wider range of soil mulching compositions.

Description

The invention relates to the chemistry of synthetic substances - polymeric in a mixture with organic and natural substances, for example, for urban and agricultural purposes, or to compositions for mulching various types of soils, lawns, park areas.

Previously known was the composition of the mulching coating in which polyacrylamide, urea, lignosulfonate, potassium chloride and water were used, in the following ratio, wt.%: Polyacrylamide 0.25-0.75, lignosulfonate 0.5-1.5, urea 0 , 4-0.8, potassium chloride 1-3, water the rest (Russian patent No. 2034899 C1, 1995, class of international classification of patents C09K 17/00).

But such a patent did not use natural materials - this is a significant drawback. In nature, there are many materials suitable for this - many mosses, different types of wood waste: bark, shavings, wood chips. Moreover, different types of wood can be combined with different types of synthetic materials - polymers, their waste - if they are harmless to the environment.

In the invention, the technical result is the use of numerous types of natural materials, that is, the expansion of the arsenal of compositions for mulching soils.

This result is achieved in that the composition of the mulching coating according to the invention contains lignosulfonate, urea, Na-carboxymethyl cellulose, potassium chloride, and as natural additives moss of the species Andreaeopsida and pine needles Pinus koraiensis, water, wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss species Andreaeopsida 10-15 pine needles Pinus koraiensis 8-9 water rest

As options, the following compositions were invented, in which important ratios for moss and needles were changed (selected):

moss species Andreaeopsida 10-15 pine needles Pinus koraiensis 9.1-9.5

or

moss species Andreaeopsida 10-15 pine needles Pinus koraiensis 9.8-11

or

moss species Andreaeopsida 15,5-17 pine needles Pinus koraiensis 8-9

or

moss species Andreaeopsida 17.8-18 pine needles Pinus koraiensis 8-9

or

moss species Andreaeopsida 17.8-18 pine needles Pinus koraiensis 9.8-10

The composition is prepared as follows.

These ingredients are individually milled and then mixed in an aqueous medium.
