Abstract
The invention discloses an anti-fracture compression-resistant board and a preparation method thereof. The anti-fracture compression-resistant board consists of the following components in parts by weight: 32 to 36 parts of silicate cement powder, 11 to 13 parts of lignocelluloses, 3 to 4 parts of hydroxypropyl starch, 5 to 6 parts of polyurethane, 12 to 15 parts of bromide epoxy resin, 12 to 14 parts of polyvinyl chloride and 12 to 14 parts of water. The anti-fracture compression-resistant board is prepared in steps of mixing, heating, stirring, board forming and the like. The prepared board is good in anti-fracture and compression-resistant performance.
Description
Technical field
The present invention relates to a kind of sheet material and preparation method thereof, particularly relate to a kind of anti-folding and anti-pressing sheet material and preparation method thereof.
Background technology
The concrete composition of sheet material and the condition of plate forming have larger impact to the fracture resistance of sheet material and compressive property.Wherein, solids component is too much, and sheet material compressive property is better, if viscous substance is too much, the fracture resistance of sheet material has larger lifting.Ultimate compression strength is too low, can produce deformation to a certain degree, affect the use of sheet material when sheet material bears high pressure.Folding strength is too low, when being subject to external impacts, easily the phenomenons such as bending occurring, affecting the performance of sheet material.Therefore need to possess higher fracture resistance and compressive property simultaneously.
Summary of the invention
The technical problem solved: common sheet material fracture resistance, the problem that compressive property is low.
Technical scheme: the invention discloses a kind of anti-folding and anti-pressing sheet material, anti-folding and anti-pressing sheet material is made up of according to weight ratio following composition: silicate cement powder is 32 ~ 36 parts, lignocellulose is 11 ~ 13 parts, hydroxypropylated starch is 3 ~ 4 parts, urethane is 5 ~ 6 parts, brominated epoxy resin is 12 ~ 15 parts, polyvinyl chloride is 12 ~ 14 parts, water is 12 ~ 14 parts.
A kind of anti-folding and anti-pressing preparation of plates method, preparation method comprises the following steps: stirred pot temperature is set as 70 ~ 80 DEG C by (1), add that urethane is 5 ~ 6 parts, brominated epoxy resin is 12 ~ 15 parts, polyvinyl chloride is 12 ~ 14 parts wherein, stir; (2) in tank body, add that silicate cement powder is 32 ~ 36 parts, lignocellulose is 11 ~ 13 parts, hydroxypropylated starch is 3 ~ 4 parts, water is 12 ~ 14 parts again, stir; (3) poured into by the mixture after stirring and carry out shaping in sheet-forming machine, Heating temperature is 80 ~ 90 DEG C, and pressure is 0.07 ~ 0.08Mpa.Anti-folding and anti-pressing sheet material is obtained after cooling.
Beneficial effect: the folding strength of the sheet material that the present invention prepares is 11.3 ~ 12.6Mpa, and ultimate compression strength is 13.2 ~ 14.6Mpa.There is good fracture resistance and compressive property, can building materials field be widely used in.
