Description

It is a kind of to mould the preparation method that rattan hanging basket uses coating
Technical field
The present invention relates to technical field of coatings, and in particular to a kind of modeling rattan hanging basket uses the preparation method of coating.
Background technology
Rattan plaited typically by beat rattan (pruning the knot on rattan), pick rattan, wash rattan, shine rattan, stubborn rattan, draw rattan (digging rattan), cut rattan, More than ten procedures such as bleach, dye, weaving, painting.Rattan plaited is main using rattan branch, rattan core or bamboo as skeleton, then with rattan peel or Tender rattan core braiding is formed, the characteristics of giving full play to rattan softness, be not easily broken.
On color, mostly using the light yellow of former rattan, or processing, bleaching are white, ivory white, it appears soft elegance, Some are then equipped with coffee color, brown etc..Rattan furniture is using thick rattan as skeleton, through following closely frame, then with rattan peel, the braiding of rattan core Into finally painting or paint.
Rattan-weaved products is increasingly liked because of its elegant, simple outward appearance by masses.It is to utilize plastic extrusion to mould rattan The plastic products for the similar Rattan-shaped being made.Due to natural rattan plaited material, supply falls short of demand, so many products are using modeling now The rattan imitating of rattan etc carries out being compiled into rattan woven ware imitation product to meet the market demand.In order to ensure the service life for moulding rattan article, So coating can be used to smear modeling rattan.
