Abstract
The present invention discloses a highway normal-temperature quickly-blacktopping concrete. It is made up by using aggregate, modified tar and polyurethane performed polymer according to the weight portion ratio of 94:4:2 through the proces sof mixing and stirring treatmen at normal temp. and normal pressure. Before use the modified tar and polyurethane performed folymer are respectively stored, and when it is used for field construction, the above-mentioned two materials and aggregate are mixed according to the above-mentioned weight portion ratio and stirred so as to obtain the invented product with good elasticity, toughness, oil resistance and antifriction property. Said product can be used for blacktopping of road and highway, etc.
Description
Technical field
The present invention relates to that a kind of highway shop is black uses material, particularly a kind of highway normal temperature quick-paveing is deceived concrete.
Background technology
At present, the modified bitumen that uses is deceived in the highway shop both at home and abroad, although added various dissimilar modifier such as SBS, SBR, PE, it remains the thermoplastic body, be used for the highway shop and deceive when constructing the fusing of modified bitumen must being heated, the preheating of will gathering materials, mix under 150 ℃ of-170 ℃ of conditions, and carry out heat and roll.Construction technology complexity like this, the equipment needed thereby costliness expends the energy, and can not construct at low temperature season.
Summary of the invention
Purpose of the present invention is intended to improve above-mentioned deficiency, provides a kind of malleable good, and the black concrete of the highway normal temperature quick-paveing that can construct at normal temperatures and pressures.
The object of the present invention is achieved like this: a kind of highway normal temperature quick-paveing is deceived concrete, it by gather materials, modification tar and base polyurethane prepolymer for use as be to mix together at 94: 4: 2 with weight portion at normal temperatures and pressures.Modification tar is to be that to vacuumize dehydration back and weight portion under 100 ℃ of temperature be that 10 the short connection of rubber agent mixes at normal temperatures and pressures and forms for 100 coal tar by weight portion.The agent of the short connection of rubber is to be 3 of 30-40% by percentage by weight, 3 '---dichloride base---4,4 '---diaminodiphenyl-methane, percentage by weight are that PPOX dihydroxylic alcohols and the acrylic acid of 60-70% is heated under the normal pressure to 60 ℃ of mixing in reactor, reduce to normal temperature then and form.Acrylic acid volume be 3,3 '---dichloride base---4,4 '---the 0.2-5% of diaminodiphenyl-methane and PPOX dihydroxylic alcohols gross weight.Base polyurethane prepolymer for use as is to be that the PPOX trihydroxylic alcohol of 60-80% and toluene di-isocyanate(TDI) that percentage by weight is 20-40% are heated under the reactor normal pressure to 80 ℃ by percentage by weight, and pre-polymerization 4 hours is reduced to normal temperature and formed.The PPOX trihydroxylic alcohol will be heated in advance to 100 ℃.
Highway normal temperature quick-paveing of the present invention is deceived concrete application, it be with gather materials, modification tar and base polyurethane prepolymer for use as be by weight at normal temperatures and pressures mix at 94: 4: 2 stir after, the cast-in-site construction rolls, 1-2 hour initial solidification, curing in 24 hours finishes.
PPOX trihydroxylic alcohol among the present invention is a stock, linearity molecular structure; Toluene di-isocyanate(TDI) is the lengthening linear structure, 3,3 '---dichloride base---4,4 '---diaminodiphenyl-methane is a crosslinking agent.
The present invention does the agent of short connection with acrylic acid, mainly is that to utilize the acrylic acid itself be a monomer, and self just can polymerization, and a unsaturated bond CH is arranged
2=CHCOOH, it has played the bridging effect in urethane crosslinks, played the promotion crosslinked action.The modification tar that forms after it and the coal tar blend also has good fluidity, advantages such as malleable is good, bonding force is strong, oil resistivity is good, abrasion resistance is good, good airproof performance.What of acrylic acid volume can be adjusted hardening time and speed.
The specific embodiment
Embodiments of the invention are as follows:
The production method of base polyurethane prepolymer for use as is among the present invention:
With the content toluene di-isocyanate(TDI) that is weight percentage to 20-40% for the PPOX trihydroxylic alcohol of 60-80% and content that is weight percentage is raw material, drop in the reactor, under normal pressure reactor is heated to 80 ℃, normal temperature generating polyurethane performed polymer is reduced in pre-polymerization 4 hours.
Its reaction equation is as follows:
Before the reaction, the PPOX trihydroxylic alcohol will be heated in advance to 100 ℃.
The production method of the short connection of rubber agent is among the present invention:
Content is weight percentage is 3 of 30-40%, 3 '---dichloride base---4,4 '---diaminodiphenyl-methane, content be weight percentage for the PPOX dihydroxylic alcohols of 60-70% and acrylic acid be raw material, drop in the reactor, under normal pressure, reactor is heated to 60 ℃ of mixing, reduce to normal temperature and become the agent of the short connection of rubber.
The production method of modification tar among the present invention:
Be that to vacuumize dehydration back and weight portion under 100 ℃ of temperature be that 10 the short connection of rubber agent mixes at normal temperatures and pressures and forms modification tar for 100 coal tar with weight portion.
Before the use, modification tar and base polyurethane prepolymer for use as are stored respectively.
During on-the-spot the use, at normal temperatures and pressures, will gather materials by weight, modification tar and base polyurethane prepolymer for use as mixed by 94: 4: 2 and stir, the cast-in-site construction rolls, and 1-2 hour initial solidification, solidifies in 24 hours and finishes.
After modification tar and base polyurethane prepolymer for use as mix, form tar rubber cross body, its structure is:
Normal temperature and pressure is construction down, uses product of the present invention, and the various aspects of performance index all exceeds the functional parameter of present modified bitumen.
