Abstract
本实用新型公开了一种复合水泥模板，包括一木塑复合刨花板层，在木塑复合刨花板的一面或双面覆上木材加强板层，其间涂有胶层，所述的木材加强板层可采用成品木材单板层、竹条层积板、竹编席板，所述的木塑复合刨花板的芯层刨花为农业秸秆或竹材刨花。其抗弯强度及弹性模量大幅度提高，可满足建筑水泥模板的使用要求。
The utility model discloses a composite cement formwork, which comprises a wood-plastic composite particle board layer, one or both sides of the wood-plastic composite particle board are covered with a wood reinforcement board layer, and an adhesive layer is coated therebetween. The wood reinforcement board layer can be Finished wood veneer layers, bamboo strip laminated boards, and bamboo woven mat boards are used, and the core layer shavings of the wood-plastic composite particle board are agricultural straw or bamboo wood shavings. Its flexural strength and elastic modulus are greatly improved, which can meet the requirements for the use of building cement formwork.
Description
Technical field
The utility model relates to a kind of complex cement template.
Background technology
Known with wood materials or non-lignocellulose plant fibre material and the compound production wood-plastic composite artificial board of plastics technology.Chinese patent ZL95105921.1 describes timber or non-lignocellulose plant fibre wood shavings and plastics in detail or reclaims the process of plastics laminated particle-board, and this kind laminated particle-board has the advantages such as free formaldehyde in water-tolerant, good toughness, the no ordinary particle board.Can be used for various furniture, finishing, decorative boards.But in some high strength, performance application, as be used for building building cement template aspect, the flexural strength of this kind sheet material and modulus of elasticity can not satisfy instructions for use far away.Thereby limited the use of this kind wood-plastic composite panel aspect the building building cement template.
Summary of the invention
The purpose of this utility model provides a kind of flexural strength and the higher complex cement template of modulus of elasticity.
For achieving the above object, the utility model is taked following design scheme: this complex cement template, comprise a wood-plastic composite particleboard layer, and strengthen flaggy at the one side or the two-sided timber that is covered with of wood-plastic composite particleboard, scribble glue-line therebetween.
Described timber is strengthened flaggy can adopt finished product wood single-plate layer, the long-pending plate of bamboo strip layer, bamboo mat plate.
The sandwich layer wood shavings of described wood-plastic composite particleboard are agricultural stalk or bamboo wood wood shavings.
The utility model has the advantages that: flexural strength and modulus of elasticity increase substantially, and can satisfy the instructions for use of building building cement template.
Description of drawings
Fig. 1 is the utility model structural representation
The specific embodiment
As shown in Figure 1, the utility model complex cement template comprises a wood-plastic composite particleboard sandwich layer 1, strengthens flaggy 2 at the one side or the two-sided timber that is covered with of wood-plastic composite particleboard sandwich layer, scribbles adhesive phase 3 therebetween.
Described wood-plastic composite particleboard sandwich layer 1 is that plastics and wood particle mixing hot pressing form (plastic content is from 5%-95%), wherein plastics can also be polypropylene, polyethylene, polystyrene, polyvinyl chloride and other thermoplastics, and wood shavings are agricultural stalk, bamboo wood wood shavings.
The all right fiber of wood-plastic composite particleboard sandwich layer, wood powder and flake form substitute.
It is the long-pending plate of finished product wood single-plate layer, bamboo strip layer, bamboo mat plate that described timber is strengthened flaggy 2.
Described adhesive 3 is water-soluble binder, oil-soluble adhesive, hot-melt adhesive.
