Summary of the invention
The base material that the objective of the invention is to solve prior art any abrasive band does not have the technical problem of grinding function.A kind of preparation method based on the polishing emery cloth of burlap that contains matte that is suitable for machine mill is provided.The method is easy and simple to handle and cost is low, grinding capacity that the burlap fiber has itself and the sponginess of burlap have been utilized, can add sand or corresponding chopped strand dipping or scrape and soak, make in grinding process the utilization to base material more abundant, and the method arranges matte by the back side at corresponding emery cloth or sand paper, its matte easily with the hook face stickup of VELCRO, easy to loading and unloading, grinding efficiency is high, can carry out translation grinding or rotary grinding, satisfies the multiple needs such as mechanical grinding.
The objective of the invention is to realize by following technical proposal: a kind of preparation method based on the polishing emery cloth of burlap that contains matte for machine mill comprises the following steps:
Flocking forms matte after a cementing of burlap; The another side of burlap is made as grinding face.
In technique scheme, described grinding face is for being coated with primer on the burlap face, and the abrasive material that forms at the face uppper sand embedding that is coated with primer.
In technique scheme, described burlap floods or scrapes to soak and processed through glue.
In technique scheme, described flood or scrape to add in the glue that soaks abrasive material is arranged, namely adopt contain the sand dipping or to scrape and soak.
In technique scheme, described flood or scrape to add in the glue that soaks the corresponding chopped strand of this burlap is arranged.
In technique scheme, described burlap is wherein a kind of of sisal hemp cloth, gunny cloth, linen, piemarker cloth, ramie cloth, etramee, or the blended cloth of multiple fiber crops and cotton blended cloth.
In technique scheme, described primer and glue are one or more in following material: urea aldehyde and modified resin thereof, phenolic aldehyde and modified resin thereof, epoxy and modified resin thereof, acrylic acid and modified resin thereof.
Can find out from technical characterictic of the present invention, the invention has the advantages that: the method is easy and simple to handle and cost is low, grinding capacity that the burlap fiber has itself and the sponginess of burlap have been utilized, can add sand or chopped strand dipping or scrape and soak, make in grinding process the utilization to base material more abundant, and the method arranges matte by the back side at corresponding emery cloth, its matte easily with the hook face stickup of VELCRO, easy to loading and unloading, grinding efficiency is high, can carry out translation grinding or rotary grinding, satisfy the multiple needs such as mechanical grinding.The mixed and disorderly friendship structure of burlap short fiber has improved the shock resistance while burlap short fiber energy synchronous consumption of glue-line, has reduced again use cost so improved performance.Burlap generally has two kinds of forms: the one, and contain the glue of sand and solidify each position that relief sand bonds to sisal hemp cloth by dipping and then utilize this material to carry out grinding, but the relevant issues of bringing due to the determined weave of material property of sisal hemp cloth itself are as only depending on the bonding mechanical property that improves of bonding agent single-point limited, thereby the random of sisal hemp short fiber can realize the effectively bonding utilization rate that has greatly improved mechanical property and improved material of multiple spot; The 2nd, plant the sand final curing after containing the glue of sand and be coated with primer by dipping, thereby utilize the sand be implanted in inside surface and fiber to participate in together grinding, and base material does not wash destarch with water and will save widely cost and environmental contamination reduction.
Description of drawings
The present invention is described further below by accompanying drawing, wherein:
Fig. 1 is producing principle schematic diagram of the present invention;
Reference numeral 1 is that burlap 2 is that matte 3 is primers
The 4th, abrasive material.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing and embodiment:
As shown in Figure 1, take sisal hemp cloth as example, the flocking after a gluing of the present invention's sisal hemp cloth after treatment forms matte, be beneficial to paste with the hook face of VELCRO, another side can directly be made as the grinding face with grinding function, such as by the dipping or scraping to soak to add has abrasive material or the glue of chopped strand to make the one side of sisal hemp cloth possess grinding function, also can be by being coated with primer at another side, and have grinding function by planting sand formation abrasive material, then be made into required polishing emery cloth by techniques such as curing cut.Wherein sisal hemp cloth can or be scraped by dipping and be immersed in its inner abrasive material or chopped strand implanted, and strengthens its every mechanical property and planarization, and makes it possess certain grinding capacity in the process of using, and improves the utilization rate of base material.In the present invention, can directly use to contain sand or burlap chopped strand and scrape the sisal hemp cloth that soaks or flood and no longer apply primer as grinding face and plant sand.Described matte can be processed in order to allow suede that endurance is more arranged through glue.
In above-mentioned manufacturing process, described burlap can be wherein a kind of of sisal hemp cloth, gunny cloth, linen, piemarker cloth, ramie cloth, etramee, or the blended cloth of multiple fiber crops and cotton blended cloth, can reach above-mentioned performance requirement.
In technique scheme, described primer and glue are one or more in following material: urea aldehyde and modified resin thereof, phenolic aldehyde and modified resin thereof, epoxy and modified resin thereof, acrylic acid and modified resin thereof.
Disclosed all features in this specification except mutually exclusive feature, all can make up by any way.
Disclosed arbitrary feature in this specification (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
The above is only preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., within all should being included in protection scope of the present invention.
