Description

A kind of frie retardant coating for timber

Technical field

The present invention relates to a kind of frie retardant coating for timber, belong to paint field.

Background technology

Now a lot of work and the environment of life are all in the environment of high temperature, and timber easily produces fire, so fire prevention is more and more taken seriously.Burning is a kind of violent oxidizing reaction having flame to occur fast, react very complicated, burning generation and carry out possessing following three conditions simultaneously, combustiblesubstance, ignition dope and burning things which may cause a fire disaster, in order to stop the carrying out of burning, any one in the three elements in combustion processes must be cut off, such as reduce temperature, isolated air or combustiblematerials, and frie retardant coating is exactly by by the surface of paint brush at those inflammable materials, but present frie retardant coating is on the market also very single, technology awaits improving.

Summary of the invention

For the deficiencies in the prior art, the problem to be solved in the present invention is, provides a kind of frie retardant coating for timber, and viscosity is thinner, coating is thinner, easy construction, has good fire resistance and decorate properties.

For solving prior art problem, technical scheme provided by the invention is, a kind of frie retardant coating for timber, and it is made up of the raw material of following parts by weight:

Magnesium hydroxide 7-11 part, novolac epoxy 6-10 part, kaolin 3-5 part, redispersable latex powder 4-7 part, titanium dioxide 3-7 part, rare earth adhesive 2-5 part, macromole siloxanes 4-6 part, cobalt naphthenate 5-8 part, N-CYCLOHEXANE maleimide 5-11 part, polysiloxane 3-5 part, butylacetate 2-7 part, butanols 3-5 part, organic acid phosphoric acid salt 1-2 part, emulsion 3-4 part, barium sulfate 1-2 part.

The invention has the beneficial effects as follows: the frie retardant coating for timber of the present invention, viscosity is thinner, coating is thinner, easy construction, has good fire resistance and decorate properties.
