Abstract

The invention relates to novel radiation-proof putty powder which consists of 3-15 parts by weight of polyvinyl alcohol, white latex and polyurethane or allylthiourea-modified carboxymethylcellulose which are used as adhesives, 100 parts by weight of white cement, barium sulfate and ash-calcium-powder which are used as aggregate, and 1-2 parts by weight of a mixture of palm oil and acrylamide-modified carboxymethylcellulose which is used as an anti-cracking additive. The paint, namely the novel radiation-proof putty powder can effectively shield radioactive substances; after the putty powder disclosed by the invention is coated to be 0.4-0.5mm, the index of the radioactive substances is reduced to 0.2-0.4baker/Kg; moreover, the novel radiation-proof putty powder has the characteristics of high hardness, cracking prevention and washing durability and never fades away.

Description

A kind of radioprotective putty powder
Technical field
The present invention relates to a kind of formula of radioprotective putty powder, this formula strengthens the anti-aging of putty powder, high rigidity and water tolerance.
Background technology
NSJF-2A type high hard water-fastness putty rubber powder system white powder thing, adopt Germany technology to process through science, nontoxic, tasteless, "dead", cold water can be dissolved in rapidly, have dissolve fast, consumption is little, viscosity is high, film forming is fast, suspension, moisturizing, antienzyme, ageing-resistant, the shelf time long, easy to use, steady performance.With the putty powder of its preparation, not rolling up skin, film forming is fast, hardness is high, water-tolerant, anti crack performance are good when easy construction, use, is the new green environment protection type putty powder of a kind of energy water modulation.The height be made into this rubber powder is hard, water-proof putty powder can increase the bonding force of putty with exterior wall, and reduce the usage quantity about 20% of exterior coating, water resistance is good, can be more and more harder in water, and the cost of preparation putty powder will reduce about 30% than other rubber powder.Product application scope: 1. mainly make putty rubber powder in building putty powder, hard, the water-fastness putty powder for exterior wall of processing height, the colored spackling of outdoor tile, the aspects such as outdoor tile tamanori use, quality is high, effective, obtains promote the use of rapidly in national building putty powder industry.2. in building trade for the manufacture of building mortar.This product adds in the slurry of cement, sand or lime, has good agglutinating value(of coal), and is easy to mixing and condensation, and made goods are hard and unduly shrink.Control cement slurry time of coagulation, improve flexural strength and compressive strength, reduce the aspects such as shrinking percentage and there is unusual effect.As height is hard, laundry-resistant mosaic (ceramic tile) exterior wall NSJF-2A rubber powder 1.5 ~ 1.9%, white cement (black cement) 40%, dry powder 20 ~ 40%, sierozem power 20 ~ 30%, the anticracking of resistance to think of additive 1 ~ 3%, silica powder (180# sand) 20%, production method: add dry powder in putty powder stirrer, then the high hard water-fastness putty rubber powder of major ingredient NSJF-2A type and Nai Si anticracking additive mixing 2 ~ 3 minutes is added, finally add cement, sierozem power, (silica powder), forward stirs 10 minutes, reverse agitating function 10 minutes, can pack as finished product.This putty powder has following effect: 1. easy to use, add water i.e. use, according to powder: the stirring that adds water of the ratio of water=1:0.4 can construct (1 kilogram of putty powder adds water about 0.4 kilogram).Also can according to the service requirements of individual, adding water is modulated to suitable denseness and can constructs, batching can rare can be thick.The available hand blender of extensive construction stirs, better effects if.2. putty is criticized and is scraped twice its 48 hours primary solidification in surface rear, and hardness improves, and water tolerance improves.
But research and development Novel radiation-protection, anti-aging, laundry-resistant putty powder are be in bottleneck always.
Summary of the invention
The object of the present invention is to provide a kind of radiation-resistant putty powder, through scientific formula and proportioning, the obtained putty powder with high radioprotective, anti-aging, water-fastness effect.
The present invention realizes above-mentioned purpose like this:
A kind of radioprotective putty powder, comprise caking agent, aggregate, anticracking additive, counts by weight, and aggregate is 100 parts, caking agent 3-15 part, anticracking additive 1-2 part.Being more preferably aggregate is 100 parts, caking agent 12 parts, anticracking additive 1.6 parts.
Described caking agent is one or more in the carboxymethyl cellulose of polyvinyl alcohol, white glue with vinyl, urethane, Allyl thiourea modification.
Described aggregate, for being milled to 300-400 object white cement, barium sulfate and sierozem power, is counted by weight, and white cement is 10-22 part, barium sulfate 40-80 part, sierozem power 5-15 part.Preferred white cement is 20 parts, 65 parts, barium sulfate, sierozem power 15 parts.
Described anticracking additive is the mixture of plam oil and acrylic amide modified carboxymethyl cellulose, counts by weight, and plam oil is 0.1 ~ 0.8 part, and acrylic amide modified carboxymethyl cellulose is 1.0 ~ 1.2 parts.Preferred plam oil is 0.6 part, and acrylic amide modified carboxymethyl cellulose is 1.0 parts.
A preparation method for radioprotective putty powder, after white cement, barium sulfate, sierozem power fully being mixed, adds caking agent, adds anticracking additive after stirring 2-7min, and the 25-30min that reverses after rotating forward 25-30min obtains.
After adopting radioprotective putty powder of the present invention to be coated in surface of wall, its radioactive substance can be shielded effectively to greatest extent, after the putty powder of the present invention of coating one deck 0.4mm-0.5mm, near 0.2-0.4 Bake under its radioactive substance index after testing/kilogram, (penetrate in country the standard of index be < 1 Bake/kilogram), blaue fixe just uses as auxiliary material by tradition radioprotective putty powder, and blaue fixe uses as aggregate by the present invention, add appropriate high-quality white portland cement simultaneously, its effect is better than traditional radioprotective putty powder greatly, major advantage is: shielding is stronger, high hard, anticracking, water-fastness, will never fade, it is the optimal selection of finishing material in vast building property, the best of high-risk Working environment is first-selected especially, (as various big hospital, scientific research institution etc.).
