The Chinese patent publication number is that the compound usefulness of the disclosed a kind of thin slabstone of CN1850931 is epoxy binder modified, and it is made of A, B two components, and the A component is by Resins, epoxy, modified epoxy, reactive thinner, ultraviolet screening agent, inorganic powder preparation; The B component is by modified amine, promotor, coupling agent, inorganic powder preparation; Modified amine curing agent in the B component is made by aliphatic cyclic amine, aliphatic amide, glycidyl ether stepwise reaction.After this tackiness agent room temperature reaction solidified, bonding strength height, minimum, ageing-resistant, the anti-xanthochromia of shrinking percentage, freeze-thawing resistant were widely used in the bonding of stone material, cement, glass, metal, are particularly useful for the compound of marble thin plate and porcelain plate, stone matter base material.Its shortcoming is cost height, not environmental protection, poor durability.
Summary of the invention
One of technical problem to be solved by this invention is to provide a kind of epoxy cement-based adhesive, this epoxy cement-based adhesive adopts the oil-in-water epoxy emulsion that forms through special emulsifying process, given full play to the high cohesive force of Resins, epoxy, aqueous, environmental protective, the advantage that is easy to construct add inorganic coagulation material cement and have strengthened the gluing weather resistance of stone material again.
Two of technical problem to be solved by this invention is to provide the preparation method of above-mentioned epoxy cement-based adhesive.
Epoxy cement-based adhesive as first aspect present invention is characterized in that, is made up of epoxy emulsion, solidifying agent, powder three components, and the weight ratio between the three is 100: 0.05-0.1: 270-330.
In epoxy cement-based adhesive of the present invention, the solids content of epoxy emulsion is preferably 25-30.Described epoxy emulsion is an aqueous epoxy emulsion.
In epoxy cement-based adhesive of the present invention, described solidifying agent is mixed by triethylene triamine and low molecule pa resin, and both weight ratios are 1-3: 1-3.Perhaps described solidifying agent is mixed by triethylene tetramine and low molecule pa resin, and both weight ratios are 1-3: 1-3.
In epoxy cement-based adhesive of the present invention, described powder is made up of silicate cement, quartz sand, Vltra tears, lignocellulose and water reducer, and the weight ratio between them is a silicate cement: quartz sand: Vltra tears: lignocellulose: water reducer 120-150: 150-180: 0.6-0.9: 0.3-0.9: 0.6-0.9.
Described quartz sand is 40-60 order quartz sand.
Described silicate cement is preferably early-strength type 42.5 ordinary Portland cements.Described water reducer is a naphthalene water reducer.
As epoxy cement-based adhesive preparation method of the present invention, comprise the steps:
1, the preparation of epoxy emulsion
Epoxy emulsion is diluted to solids content to 25-30;
2, the preparation of solidifying agent
Triethylene triamine or triethylene tetramine and low molecule pa resin be mixed in proportion make solidifying agent;
3, the preparation of powder
A, take by weighing Vltra tears, lignocellulose, naphthalene water reducer weight sum 30-50 quartz sand doubly and put into the ball mill mixing 3-5 minute with Vltra tears, lignocellulose, naphthalene water reducer;
B, remaining quartz sand and the silicate cement that takes by weighing in proportion put into together carry out the dried 3-5 of stirring minute in the mortar mixer;
C, the compound of step a gained is put in the compound of step b gained, stirred;
4, the epoxy emulsion of step 1 gained, the solidifying agent of step 2, the powder of step 3 are packed separately, mixed during use and get final product.
Oil-in-water epoxy emulsion of the present invention is a response type because of having epoxy group(ing) and hydroxyl to give emulsion, makes the cured article of emulsion have very strong force of cohesion and bonding force, and ehter bond and hydroxyl are polar groups, help to improve wetting property and bonding strength.Ehter bond and C-C key make macromole have snappiness.Phenyl ring is given polymer emulsion with heat-resisting, freeze-thawing resistant and rigidity.The bond energy height of-C-O-key, thus the alkali resistance of emulsion improved.The Water Soluble Compound solidifying agent is soluble in the emulsion of water-based, also changes its set of dispense ratio because of construction environment or changes of seasons, to adapt to different requirements.Cement, high grade quartz sand have been given the intensity, weather resistance of epoxy cement-based stone adhesive, lower shrinkage value.Water reducer gives tackiness agent mix, intensity height, characteristics that wetting property is good.
The present invention can reach the metal when saving stone material dry suspending, stops that volatile matter is easy to after the use clean to the murder by poisoning of workman's health in the oiliness stone adhesive, prevents the accumulation of salt in the surface soil of wet combining stone material.The present invention is health environment-friendly in use, economizes on resources, safe ready.
