Description

A kind of plasticity-matrix material

Technical field

The invention provides a kind of plasticity-matrix material, belong to building decoration art work field.

Background technology

In existing building decoration, some common relief shapes and artistic sculpture often use the materials such as gypsum, cement, stone material, timber, and plastering intensity is low, easily damages; Cement products weight is large, and surface irregularity is of low grade; Stone material weight is large, and quality is hard, and tooling cost is high; The processibility of timber is good, but it is high to environmental requirement, weathering resistance is poor, needs time-based maintenance, and some plane deformation mould boards often use shaving board, and shaving board in process of production, generally can use carboxaldehyde radicals tackiness agent, its finished product can discharge free formaldehyde more or less, when free formaldehyde content is more than a definite limitation, HUMAN HEALTH can be affected, the infringement person.

Summary of the invention

The object of this invention is to provide a kind of plasticity-matrix material, make moulding or sheet material with this technologic material, its processibility is good, and cost is low, asepsis environment-protecting.

Technical scheme of the present invention is: a kind of plasticity-matrix material, it is characterized in that: be made up of compound and binding agent, compound and the complete packing of binding agent, be mixed into plastic material by the volume ratio of setting during use, and the preparation of raw material that described compound comprises following weight part becomes:

Wherein the granularity of corn stalk powder is 10 ~ 80 orders; The granularity of water-sand-powder is 50 ~ 80 orders; The filament length of straw silk is 0.5 ~ 2 centimetre, string diameter 20 ~ 30 order;

Described binding agent is made up of the raw material of following volume part:

A () degree Beaume is the sodium silicate solution 5 ~ 10 parts of 0.35 ~ 0.52

(b) waterproofing agent of organosilicon 0.001 ~ 0.002 part

Wherein sodium silicate solution and waterproofing agent of organosilicon are commercial goods.

When the matrix material of this technology uses, compound and cakingagent are mixed in proportion into plastic soft walk, can be used as the raw material of molding products; Can be used as the raw material of relief shape, artistic sculpture product; Pile up the raw material of moulding product.By compound and cakingagent packing, can be used as the printing product material of three-dimensional printer.After compound and cakingagent mixing, spontaneous curing is shaping, and advantage is: the moulding made of this technologic material or sheet material, and its processibility is good, and cost is low, asepsis environment-protecting simple for the technique that makes finished product, applied range; Owing to using corn stalk powder and straw silk powder as major ingredient, goods lightweight, cost is low, major ingredient is that fine powder can make finished surface smooth, alternative timber or building stones, using sodium silicate solution as the cakingagent of compound, nonpoisonous and tasteless, safety and environmental protection, the water-resisting agent of interpolation can solve the not water-fast defect of sodium silicate solution.
