Embodiment 1

[0020] (1) 19.85kg of tetrabromobisphenol A-diallyl ether, 3.35kg of styrene, 4.4kg of acrylic acid, 17.5kg of butyl acrylate, and 2.9kg of methyl methacrylate were premixed to obtain mixed monomers. First, add 0.5kg sodium lauryl sulfate, 1.4kg nonylphenol polyoxyethylene ether and 16kg deionized water into the reactor, start stirring and raise the temperature, and add 1 / 3 mixed monomer for pre-treatment when the temperature rises to 82°C. Emulsify for 30 minutes, then add the remaining mixed monomers and all the initiators dropwise, and finish dropping in 90-120 minutes. Make sure that the monomers are dropped before the initiators, and at the same time raise the temperature to 85°C-87°C. After dripping, keep warm for 40-60 minutes to get milky white styrene-acrylic emulsion with strong blue light.

Abstract

The invention discloses a flame-retardant adhesive for timer and a preparation method thereof. The adhesive comprises the following compositions in percentage by mass: 80.0 to 85.0 percent of bromocarbon styrene-acrylic emulsion, 1.0 to 2.0 percent of diantimony trioxide, 4.0 to 8.0 percent of chlorinated paraffin, and 10.0 percent of deionized water. The preparation method comprises the following steps: adding a proper amount of the deionized water, the diantimony trioxide, the chlorinated paraffin and the titanium pigment orderly into a multi-purpose dispersion mill for high-speed dispersion for 30 to 60 minutes; reducing the stirring speed, adding the bromocarbon styrene-acrylic emulsion into the mixture, and dispersing the mixture for 20 to 40 minutes once again; and grinding the obtained product to a needed fineness by a cone mill, adding the powder into the multi-purpose dispersion mill to be dispersed for 10 to 20 minutes, and obtaining the flame-retardant adhesive for the timer.

Description

technical field [0001] The invention relates to a flame-retardant adhesive, in particular to a method for preparing an environment-friendly flame-retardant adhesive for wood. Background technique [0002] Adhesives commonly used in wood panel processing include urea-formaldehyde resin, phenolic resin and vinyl resin. Urea-formaldehyde resin is the most consumed type of adhesive in my country's wood processing industry due to its low price, but this type of adhesive exists. The shortcomings of poor water resistance and large formaldehyde release. With the increasingly stringent environmental protection regulations and the improvement of people's health awareness, the control requirements for free formaldehyde release in adhesives are becoming more and more stringent. However, the mole of formaldehyde / urea in urea-formaldehyde resin Therefore, the urea-formaldehyde adhesives are limited in wood processing and application, while the vinyl resin adhesives are affected by water res...
