Embodiment 1

[0028] 1. Surface modification of aluminum hydroxide and magnesium hydroxide

[0029] Preheat the magnetic stirrer to about 100°C, put the aluminum hydroxide powder into the magnetic stirrer, divide the NDZ-201 titanate coupling agent with an amount of 1.5% aluminum hydroxide into three parts, and add one part to the hydroxide In the aluminum, start the mixer and beat on low speed. Add one portion every minute, stir at high speed for about 2 minutes after adding all three portions, take it out and put it in a beaker for later use.

[0030] Preheat the magnetic stirrer to about 100°C, put the magnesium hydroxide powder into the magnetic stirrer, divide the KH570 silane coupling agent with an amount of 1.5% magnesium hydroxide into three parts, add one part to the magnesium hydroxide, and start With mixer, blend on low speed. Add one portion every minute, stir at high speed for about 2 minutes after adding all three portions, take it out and put it in a beaker for later use. ...

Embodiment 2

[0034] Preparation of flame-retardant coatings for wood-plastic composites containing inorganic flame retardants

[0035] Preheat the magnetic stirrer to about 60°C, add 100 parts of aluminum hydroxide (ATH), 50 parts of magnesium hydroxide (MH) and 100 parts of epoxy resin (E-44), 10 parts of aluminum oxide, After 5 parts of microcapsule red phosphorus, 20 parts of expandable graphite, and 8 parts of zinc borate, keep stirring for 30 minutes. After the powder is mixed evenly in the resin, filter, add curing agent (T31) and ethanol, and stir for 10 minutes to mix evenly. Can be painted outside, all the other are identical with embodiment 1.

Embodiment 3

Abstract

The invention relates to a wood-plastic composite inflaming-retarding coating containing inorganic fire retardant, comprising the following ingredients according to parts by weight: 100 parts of epoxide resin, 10-20 parts of ethanol, 0.9-1.5 parts of NDZ-201 titanate coupling agent, 0.45-0.75 part of KH570 silane coupling agent, 25-30 parts of curing agent, 60-100 parts of aluminium hydroxide, 30-50 parts of magnesium hydroxide, 10 parts of alumina, 5-15 parts of microcapsule red phosphorus, 10-20 parts of expanded graphite, and 4-12 parts of zinc borate. The wood-plastic composite inflaming-retarding coating has the advantages that pollution to environment is reduced owning to the usage of a low-smoke nontoxic halogen-free inflaming-retarding agent, and in the wood-plastic composite inflaming-retarding coating, the disadvantage that as the magnalium fire retardant has overhigh filler quantity, the processing property or physical property of the material can be reduced is overcome owning to the wood-plastic composite inflaming-retarding coating, and the inflaming-retarding coating has high surface hardness, so that the inflaming-retarding coating has good abrasive resistance, chemical resistance and aging resistance. The fineness of the inflaming-retarding coating is less than 90mum, the adhesive force is zero level, the surface drying time is less than 1.5h, and the hard drying time is less than 24h.

Description

technical field [0001] The invention relates to a flame-retardant coating containing an inorganic flame retardant applied to wood-plastic composite materials, and belongs to the technical field of flame-retardant coatings. Background technique [0002] Wood-plastic composite materials are mainly composed of hydrocarbon elements, which are easy to burn when exposed to open flames or heated. Therefore, the application of wood-plastic composite materials is limited in many aspects. In order to expand the use and market of wood-plastic composite materials, wood-plastic composite products It should be developed in the direction of flame retardancy. With the enhancement of people's awareness of environmental protection and safety, low-smoke, non-toxic, halogen-free flame retardants have become the development trend of flame retardants. Among them, inorganic flame retardants have good thermal stability, do not produce corrosive gases, are non-volatile, and have excellent Durable, ...
