Problems solved by technology

[0003] Currently commonly used epoxy resin flame retardant technologies include halogen-containing flame retardants and intumescent flame retardants. However, in view of the great harm of halogen elements to the environment and the human body, halogen-containing technologies are gradually being eliminated. As for IFR (intumescent flame retardant Although it is widely praised for its environmental protection and smoke suppression, higher additions usually lead to deterioration of mechanical properties. Therefore, it is of great significance to promote the development of flame retardant technology in the direction of high efficiency, smoke suppression, and environmental protection;

preparation example Construction

[0035] M(OH)(OCH 3 ) is prepared as follows:

[0036] Ni(OH)(OCH 3 ), Co(OH)(OCH 3 ) or Mg(OH)(OCH 3 ) The preparation method has been recorded and prepared in the existing literature, and will not be described too much here;

example 1

[0037] Example 1, the preparation of M(OH)(OCH containing Ni and Co two elements 3 ), the M(OH)(OCH 3 ) is expressed as CoNi(OH)(OCH 3 ), and its preparation process includes as follows: cobalt acetate tetrahydrate and nickel acetate tetrahydrate are premixed according to the molar ratio of Ni:Co of 1:9 and then dissolved in methanol, and the precursor is obtained after vigorous stirring for 12h. The body was sealed in a Teflon reactor, and it was placed in an oven at 180 degrees Celsius for 48 hours, and then filtered three times with methanol to obtain the first product, which was dried overnight in a 60 degrees Celsius oven for 8-12 hours to obtain CoNi(OH)(OCH containing Ni and Co 3 ) lavender uniform powder, at this time CoNi(OH)(OCH 3 ) in the ratio range of Ni:Co is 0.1-1;

example 2

[0038] Example 2, the preparation of M(OH)(OCH containing Mg and Co two elements 3 ), the M(OH)(OCH 3 ) is expressed as MgCo(OH)(OCH 3 ), the preparation process includes the following steps: cobalt acetate tetrahydrate and magnesium acetate tetrahydrate are premixed in a molar ratio of Mg:Co of 1:9 and then dissolved in methanol, and the precursor is obtained after vigorously stirring for 12 hours. The body was sealed in a Teflon reactor, and it was placed in an oven at 180 degrees Celsius for 48 hours, and then filtered three times with methanol to obtain the first product, which was dried overnight in a 60 degrees Celsius oven for 8-12 hours to obtain MgCo(OH)(OCH) containing two elements of Mg and Co 3 ) uniform powder, at this time MgCo(OH)(OC H 3 ) in the ratio range of Mg:Co is 0.1-1;

Abstract

The invention relates to the technical field of flame retardants or composite materials, in particular to a flame retardant, a flame-retardant and smoke-suppression composite material and a preparation method, and provides the following scheme that the flame retardant comprises the following components: a substance obtained by modifying M (OH) (OCH3) by using transition metal, transition metal inorganic salt and/or nitrogen and phosphorus flame-retardant groups, wherein M comprises any two or one of Mg, Ni and Co, the flame retardant is applied to preparation of the flame-retardant and smoke-suppression composite material. The substance obtained by modifying M (OH) (OCH3) by using transition metal, transition metal inorganic salt and/or nitrogen and phosphorus flame-retardant groups can be used as the flame retardant or an effective flame-retardant component of the flame retardant, and the flame-retardant and smoke-suppression composite material can be prepared by mixing the substance obtained by modification with a matrix resin material. In the embodiment, M (OH) (OCH3)-coated Ni obtained by modifying M (OH) (OCH3) and M (OH) (OCH3) are respectively added into the pure epoxy resin, and both the M (OH) (OCH3)-coated Ni and the M (OH) (OCH3) can play a role in flame retardance and smoke suppression on the pure epoxy resin.

Description

technical field [0001] The invention relates to the field of flame retardants or composite materials, in particular to a flame retardant, a flame-retardant and smoke-suppressing composite material and a preparation method. Background technique [0002] As one of the most important synthetic polymer materials, epoxy resin has been widely used in integrated circuits, adhesives, laminates, industrial tools and other fields due to its excellent properties such as low shrinkage, high stability, and corrosion resistance. Oxygen resin is easy to burn, which seriously reduces its fire safety and reliability. What is more serious is that it will release a large amount of toxic smoke during the combustion process, which is very harmful to the environment and human body. Nowadays, with With the continuous improvement of environmental protection awareness and safety production standards, ensuring good flame retardancy and smoke suppression has become an important prerequisite for the ap...
