RU2473650C1 - Mulching composition (versions) - 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, Takakiopsida moss and Juniperus virginiana 'Glauca' juniper 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, Takakiopsida moss 10-15, Juniperus virginiana 'Glauca' juniper needles 8-9, and water - the balance. Other versions of polymer-natural mulching compositions are also disclosed.

EFFECT: wider range of soil mulching compositions.

Description

The invention relates to the chemistry of synthetic substances - polymeric mixed 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, such a mulching coating composition was known 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 С09К 17/00).

But such a composition did not use natural materials - this is a significant drawback. In nature, there are many materials suitable for this - many mosses, various 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 environmentally friendly.

In the present invention, the technical result is the use of numerous types of natural materials, that is, expanding 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 Takakiopsida and juniper needles Juniperus virginiana 'Glauca', water in the wake. wt.%:

lignosulfonate 0.1-0.4 urea 0.2-0.6 Na-carboxymethyl cellulose 0.3-0.4 potassium chloride 1-3 moss species Takakiopsida 10-15 juniper needles Juniperus virginiana 'Glauca' 8-9 water rest

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

moss species Takakiopsida 10-15 juniper needles Juniperus virginiana 'Glauca' 9.1-9.5

or

moss species Takakiopsida 10-15 juniper needles Juniperus virginiana 'Glauca' 9.8-11

or

moss species Takakiopsida 15,5-17 juniper needles Juniperus virginiana 'Glauca' 8-9

or

moss species Takakiopsida 17.8-18 juniper needles Juniperus virginiana 'Glauca' 8-9

or

moss species Takakiopsida 17.8-18 juniper needles Juniperus virginiana 'Glauca' 9.8-10

The composition is prepared as follows.

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