Abstract
The invention discloses a wallpaper coated with a flame retardant and antistatic coating. The wallpaper consists of base paper and modified waterborne polyurethane coating coated on the surface of the base paper. The prepared coating material not only adheres to the no toxicity, heat resistance, environmental protection and other characteristics of waterborne polyurethane coating, but also has the advantages of water resistance, stain resistance, and slippery handfeel, etc. The added cationic starch-nano activated alumina composite dispersion liquid taking polyvinyl alcohol as the protective colloid has good affinity with polyurethane emulsion, can endow the coating with excellent tackifying, heat resistance, flame retarding, waterproofing and reinforcing efficacy, also has certain antistatic effect, and can improve the safety of the wallpaper. The wallpaper made from the coating is safe and durable, wear-resistant, can be scrubbed repeatedly, and has very strong market competitiveness.
Description
Technical field
The present invention relates to environmental protection wall paper technical field, particularly relate to a kind of wallpaper applying flame-retardant and anti-static type coating.
Background technology
Wallpaper has another name called wallpaper, because of it, to have color various, pattern enriches, luxurious style, safety and environmental protection, easy construction, the advantages such as affordable are applied more and more extensive in house ornamentation, mostly by hanging raw stock and blade coating, the coating in body paper surface forms wallpaper, and the character of coating determines the function of wallpaper greatly, current indoor decoration wallpaper mainly tends to environmental protection, the developing direction of safety, the selection of coating material is also with environmental protection, safety is main, market is also emerged in large numbers the Environment-friendlywallpaper wallpaper of diversified Mobyneb coating decoration, such as polyvinyl chloride resin coating, flame retardant coating, diatomite purification coating etc., but still there is inadequate environmental protection in these coatings in the use of reality, poor with base material laminating degree, affected by environmently easily to peel off, problem that difficulty of construction is higher etc., construction and instructions for use cannot be met safely.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of wallpaper applying flame-retardant and anti-static type coating.
The present invention is achieved by the following technical solutions:
A kind of wallpaper applying flame-retardant and anti-static type coating, this wallpaper is made up of base paper and the modified aqueous polyurethane coating that is coated on base paper surface, described modified aqueous polyurethane coating is made up of the raw material of following weight portion: isophorone diisocyanate 25-30, PTMG 12-15, dihydromethyl propionic acid 4-6, BDO 6-8, triethylamine 4-5, polyether silicone oil 1-2, nano active aluminium oxide 4-6, cationic starch 1-2, polyvinyl alcohol 0.4-0.5, neopelex 0.01-0.02, deionized water are appropriate.
Described modified aqueous polyurethane coating production is:
(1) first neopelex, polyvinyl alcohol, cationic starch being dissolved in completely 20-30 weight portion temperature is in the deionized water of 50-60 DEG C, be mixed with mixed solution, subsequently nano active aluminium oxide is added in solution, leave standstill after high speed shear dispersion 40-50min, making with polyvinyl alcohol is that the cationic starch-nano aluminium oxide dispersion liquid of protecting colloid is for subsequent use;
(2) in four-hole bottle, PTMG is added, it is 120 DEG C in temperature, vacuum is the 1-2h that dewaters under the condition of-0.05-0.09MPa, room temperature is cooled to after dehydration terminates, then isophorone diisocyanate is added, and be heated to 70-75 DEG C, dihydromethyl propionic acid is added after hybrid reaction 50-60min, 1, 4-butanediol, continue hybrid reaction 3-4h, polyether silicone oil reaction 25-35min is added after reaction terminates, room temperature is cooled to after reaction terminates, add triethylamine neutralization, add nano-powder dispersion liquid prepared by appropriate deionization hydration step (1) subsequently, high speed shear emulsification obtains the polyether silicone oil modified aqueous polyurethane emulsion that solid content is 40-45%, obtain described coating paste.
Advantage of the present invention is: the present invention has prepared a kind of aqueous polyurethane coating slurry of polyether silicone oil modification, this coating material has not only acted on the features such as nontoxic, heat-resisting, the environmental protection of aqueous polyurethane coating, also there is smooth etc. the advantage of water-fast, resistant, feel, the cationic starch using polyvinyl alcohol as protecting colloid added-nano active alumina composite dispersion liquid, good with polyaminoester emulsion compatibility, the excellent thickening of coating, heat-resisting, fire-retardant, water-fast, enhancing effect can be given, also there is certain antistatic property simultaneously, improve the security of wallpaper; The wallpaper safety durable prepared with this coating, wear-resistant, repeatedly can clean, there is the very strong market competitiveness.
