Abstract
The present invention relates to an adhesive and its preparation method. Said adhesive is formed from water-glass, high-temperature toughening agent and water. The modulus of said water-glass is greater than or equal to 2, the high-temperature toughening agent is saccharide. Its preparation method is characterized by that the high-temperature toughening agent and water-glass are added in the water, and uniformly dissolved, and the honey as a component is added in the adhesive, so that the precoated layer coated by using said adhesive can not be cracked or damaged.
Description
Technical field
The present invention relates to a kind of caking agent and preparation method thereof, relate in particular to a kind of precoated layer caking agent that is used for the self-fluxing alloyed powder coating and preparation method thereof.
Background technology
In mechanical manufacturing field, the method that the surface through being commonly used in mechanical component adds alloy coat improves surface strength, surface abrasion resistance, the surface hardness of mechanical component and does corrodibility.Method commonly used be with methods such as laser, induction, plasma, oxygen-acetylene torch and vacuum sinterings with the self-fluxing alloyed powder cladding in the metal machinery part surface.These methods all need prior at the mechanical precoated layer that needs to make on the part surface self-fluxing alloyed powder of metal, common employing oxygen-acetylene torch spraying method, plasma spraying method and hypersonic flame spraying method in making the precoated layer process.These methods all can cause the huge waste of powdered alloy, and the effective rate of utilization of powdered alloy only is 30～70%, and the precoated layer that these methods are made had ablation phenomen, and the quality of cladding coating is had disadvantageous effect.
This just needs a kind of method, can make powdered alloy be coated in the metal machinery part surface equably, waste simultaneously little, the utilization ratio height.A kind of method that has now is to use water glass to mix with powdered alloy as caking agent and soak into, and then it evenly is applied to the metal machinery part surface, again through seasoning or dry the formation precoated layer.The shortcoming of this method is because the dried fragility of water glass makes the coated precoated layer intensity of metal machinery part surface low, very easily damages or cracking, can't reach the result of use of expection.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this invention is to provide a kind of caking agent and preparation method thereof.This caking agent can be coated on the metal machinery part surface efficiently with powdered alloy, and the intensity height, do not ftracture, not fragile.
The objective of the invention is to be achieved through the following technical solutions:
A kind of caking agent is made up of water glass, the agent of high temperature toughness and water, and its weight percent is:
Water glass 15%～20%;
High temperature toughness agent 0.2%～0.9%;
Water surplus.
The modulus of described water glass is more than or equal to 2.
The agent of described high temperature toughness is a carbohydrate, can select honey or brown sugar for use.
A kind of preparation method of described caking agent is characterized in that, making processes comprises:
The agent of high temperature toughness and the water glass of predetermined weight per-cent are added in the water of predetermined weight per-cent, make its uniform dissolution.
Described caking agent manufacturing processed also comprises:
The high temperature toughness agent of predetermined weight per-cent and water glass are added in the water of predetermined weight per-cent, heat then and make its uniform dissolution.
Described caking agent manufacturing can also be following method:
A, from the water of predetermined weight per-cent, get some and be heated to more than 50 ℃;
B, adding high temperature toughness agent in this hot water make its uniform dissolution;
C, the water glass of above-mentioned solution and predetermined weight per-cent is added in the remaining water, stir.
Mixes with self-fluxing alloyed powder with the caking agent for preparing during use and soak into, then it is evenly coated in metal machinery and needs the part surface, through seasoning or dry the formation precoated layer.And then with methods such as laser, induction, plasma, oxygen-acetylene torch and vacuum sinterings with the self-fluxing alloyed powder cladding in the metal machinery part surface.Thereby obtain high strength, high-wearing feature and high corrosion resistance at workpiece surface.
By above technical scheme caking agent of the present invention as can be known, to form by water glass, the agent of high temperature toughness and water, the modulus of water glass is more than or equal to 2.The agent of high temperature toughness is a carbohydrate, can be honey or brown sugar.Making method is that the high temperature toughness agent of predetermined weight per-cent and water glass are added in the water of predetermined weight per-cent, makes its uniform dissolution.Because of added the agent of high temperature toughness in this caking agent, the agent of high temperature toughness is that its major ingredient of honey, brown sugar or asccharin is carbohydrate, has viscosity and toughness when high temperature.So the precoated layer that coats can not ftracture, damage.
Embodiment
The specific embodiment of its composition of a kind of caking agent of the present invention and preparation method thereof is:
A kind of caking agent is made up of water glass, the agent of high temperature toughness and water, and its weight percent can be (seeing Table 1):
The modulus of optional water glass is 3, is example with embodiment 3, and its preparation method comprises:
Step 1, from the water of predetermined weight per-cent, get an amount of some and be heated to more than 50 ℃;
Step 2, to add weight percent in this hot water be 0.55% honey, makes its uniform dissolution;
Step 3, be that 17.5% water glass adds in the remaining water, stir above-mentioned solution and predetermined weight per-cent.
The modulus of above-mentioned water glass requires just can use more than or equal to 2;
Above-mentioned high temperature toughness agent can also be adopted other glucides such as brown sugar except adopting honey.
